A stye, or hordeolum, is an acute, painful ocular infection involving the sebaceous glands of the upper or lower eyelid. This lesion presents as a localized, pustular swelling with erythema and tenderness along the eyelid margin. While generally self-limiting and benign, hordeola can result in considerable discomfort and functional impairment. Styes are commonly caused by bacterial infection, most often Staphylococcus aureus, which invades the sebaceous glands of the eyelid. Risk factors include poor eyelid hygiene, chronic blepharitis, immunosuppression, and conditions like diabetes. The lesion evolves from the obstruction and subsequent infection of the eyelid's sebaceous glands, leading to localized purulent inflammation and pustule formation. Diagnosis is primarily clinical, based on the characteristic appearance of the eyelid. Treatment typically involves warm compresses, proper eyelid hygiene, and, in persistent cases, antibiotic ointments or oral antibiotics. Rarely, surgical drainage may be necessary. The prognosis is generally favorable, with most cases resolving within a week to 10 days without complications. This activity for healthcare professionals is designed to enhance learners' proficiency in evaluating and managing hordeola.

A stye or hordeolum is a common problem involving the eye seen in primary and urgent care settings. Styes are manifestations of upper or lower eyelid infection. Classically, the lesion appears as a small pustule along the eyelid margin. Hordeola may be differentiated from a chalazion, which tends to involve less inflammation and follows a more chronic course.[1][2] A hordeolum involves an acute, localized infection of the sebaceous glands of the eyelid. The lesion often becomes a red, swollen, and tender nodule, typically near the eyelid margin. Styes are categorized into external hordeola, involving the glands of Zeis or Moll, located at the base of the eyelashes, and internal hordeola, affecting the deeper meibomian glands within the tarsal plate.[3] Styes are a common condition across all age groups, primarily caused by Staphylococcus aureus. Self-limiting, untreated, or improperly managed styes usually lead to complications, such as chalazia, preseptal cellulitis, and, rarely, orbital cellulitis.[4] The anatomy of the eyelid plays a crucial role in the development of styes: Glands of Zeis: Sebaceous glands at the base of eyelash follicles. These glands may develop external hordeola (see Image. External Hordeolum of the Upper Eyelid). Glands of Moll: Modified sweat glands near the eyelash follicles that may also develop external styes. Meibomian glands: Sebaceous glands embedded in the tarsal plate that produce the lipid layer of the tear film. These glands are often blocked or infected in internal hordeola. Orbital septum: A fibrous barrier separating the superficial and deep structures of the orbit, helping to prevent the deeper spread of infection.[5] Styes generally develop over a few days due to gland blockage and subsequent bacterial colonization. In most cases, the lesion progresses to form a small abscess, draining spontaneously or resolving with conservative treatment. Untreated or recurrent styes may evolve into a chalazion, a chronic, noninfectious granulomatous lesion.[6]

Styes generally develop over a few days due to gland blockage and subsequent bacterial colonization. In most cases, the lesion progresses to form a small abscess, draining spontaneously or resolving with conservative treatment. Untreated or recurrent styes may evolve into a chalazion, a chronic, noninfectious granulomatous lesion.[6] Styes can spread in different ways, potentially leading to complications if not properly managed. In localized hordeola, the infection remains confined to the affected gland and surrounding eyelid tissues.[7] If untreated, the infection can progress to preseptal cellulitis, involving the tissues around the eye. In rare cases, the infection may cross the orbital septum and cause orbital cellulitis, which requires urgent medical intervention.[8] Recurrent styes are often linked to underlying conditions such as blepharitis, rosacea, and diabetes.[9][10]

Hordeola arise from an acute bacterial infection of the sebaceous glands of the eyelid. Around 90% to 95% of the lesions are due to Staphylococcus aureus, with Staphylococcus epidermidis being the 2nd most common cause. An external hordeolum represents a localized abscess formation of the follicle of an eyelash, whereas an internal hordeolum is an acute bacterial infection of the meibomian glands of the eyelid.[11][12] In contrast, a chalazion is an acute or chronic eyelid inflammation secondary to an obstruction of the tarsal plate's oil glands (meibomian or Zeis) alongside a foreign body reaction to sebum. Conditions that block the normal drainage of sebaceous glands, such as hordeola, acne rosacea, and blepharitis, can contribute to the development of chalazia.[13] Hordeolum Risk Factors The key factors contributing to stye formation: Bacterial infection: S aureus is the primary causative organism for most styes. However, other bacteria, such as S epidermidis or, less commonly, streptococcal species, may also be involved. Glandular involvement: An external hordeolum results from an infection of the glands of Zeis (sebaceous glands at the base of eyelash follicles) or Moll (modified sweat glands). An internal hordeolum is a deeper infection involving the meibomian glands within the tarsal plate. Predisposing factors: Conditions that increase a person's vulnerability to hordeolum formation include: Inadequate cleaning of the eyelid margins promotes bacterial colonization and blockage of sebaceous glands. Chronic eyelid conditions like blepharitis and meibomian gland dysfunction can also cause hordeola. Blepharitis leads to obstruction of eyelid glands. Meibomian gland dysfunction also contributes to stye formation.[14] Systemic conditions that may increase susceptibility to stye formation include diabetes and rosacea. Diabetes increases susceptibility to infections due to impaired immune function. Chronic inflammation in rosacea affects meibomian gland function. Improper contact lens hygiene introduces bacteria to the eyelid margin, raising the risk of styes.[15] Frequent eye makeup use blocks sebaceous glands. Poor eye makeup removal practices encourage bacterial growth. Stress weakens the immune system, predisposing individuals to styes. Similarly, immunosuppression from conditions like HIV or chemotherapy heightens vulnerability.[16] Mechanism of Stye Formation

Improper contact lens hygiene introduces bacteria to the eyelid margin, raising the risk of styes.[15] Frequent eye makeup use blocks sebaceous glands. Poor eye makeup removal practices encourage bacterial growth. Stress weakens the immune system, predisposing individuals to styes. Similarly, immunosuppression from conditions like HIV or chemotherapy heightens vulnerability.[16] Mechanism of Stye Formation The combination of gland obstruction, whether due to meibomian dysfunction, debris, inflammation, or bacterial colonization, results in acute inflammation of the gland. A localized abscess also forms, manifesting with redness, swelling, and tenderness. By addressing the underlying causes and predisposing factors, clinicians can effectively prevent styes and manage recurrent cases.[17]

While hordeola are very common, the exact incidence is unknown. Every age and demographic is affected, although a slightly increased incidence is observed among patients aged 30 to 50. Prevalence differences among populations worldwide are unknown. Patients with chronic conditions such as seborrhoeic dermatitis, diabetes, and hyperlipidemia may also be at increased risk.[18][19] Prevalence in Different Regions Styes are common worldwide, affecting individuals of all ages. While the exact prevalence is not well-documented, the occurrence is significantly influenced by risk factors such as poor eyelid hygiene, blepharitis, and meibomian gland dysfunction. Styes are more frequently observed in regions with poor access to healthcare or suboptimal hygiene practices.[20] Sex Distribution Styes are slightly more common in female individuals. This trend is attributed to the frequent use of cosmetics and eye makeup in this group, which can block gland ducts and exacerbate bacterial colonization.[21] Age Distribution Styes can occur in all age groups, but certain factors increase the risk for some individuals. Frequent eye rubbing and inadequate eyelid hygiene can make children and adolescents vulnerable to developing a stye. Conditions that increase susceptibility to hordeolum formation in adults include chronic blepharitis, rosacea, and meibomian gland dysfunction. Age-related changes in meibomian gland function and tear production can cause recurrent styes in older adults.[22] Associated Risk Factors Styes are more frequent in individuals with the following conditions: Blepharitis, which causes chronic eyelid inflammation Diabetes, which impairs the immune response Rosacea, which affects meibomian gland function and increases susceptibility to eyelid infections [23] By understanding the epidemiology of styes, healthcare providers can better identify at-risk populations and emphasize preventive strategies, including proper eyelid hygiene and timely treatment of underlying conditions.[24]

S aureus infection contributes to the development of a hordeolum, the manifestations of which depend on which of the eyelid gland types is affected. Involvement of the Zeis and Moll glands, also known as the ciliary glands, causes pain and swelling at the base of the eyelash, often with localized abscess formation. This condition, termed "external hordeolum," produces the typical appearance of a stye, with a localized pustule at the eyelid margin. The meibomian glands, which are modified sebaceous glands located within the eyelid's tarsal plate, produce an oily layer that helps maintain proper eye lubrication. Acute meibomian gland infection produces an internal hordeolum. Due to its deeper location within the eyelid, an internal hordeolum has a less defined appearance compared to an external hordeolum.[25] By comparison, chalazia develop due to mechanical obstruction and dysfunction of the meibomian glands, leading to stasis and blockage of sebum release. Lesions typically have a subacute to chronic course, presenting as painless nodules within the eyelid or along the lid margin.[26] External and internal hordeola lead to blockage of the eyelid gland ducts, followed by neutrophilic infiltration, causing localized inflammation, abscess formation, and tenderness. The most common findings include redness, swelling, and tenderness localized to the eyelid margin. Occasionally, a visible pus point or discharge may develop, particularly in external hordeola. Timely management can prevent progression to complications like preseptal cellulitis or chalazion formation.[27]

Key Features Histopathological examination is not routinely performed for styes but may be considered in atypical, persistent, or recurrent cases to rule out malignancy or other underlying conditions. The key histological features typically observed in a stye include: Acute suppurative inflammation: Evidence of acute suppurative inflammation includes neutrophilic infiltration in and around the affected gland. The sebaceous glands of Zeis are involved in external hordeola, while the meibomian glands are affected in internal hordeola. Abscess formation with central necrosis may also be observed in advanced cases.[28] Edema and vascular congestion: Swelling and engorgement of nearby blood vessels occur due to the acute inflammatory response. Fibrosis: This feature is found in chronic or recurrent cases. Chronic inflammation is characterized by granulomatous reaction, and lipid-laden macrophages may be seen if the stye progresses to or coexists with a chalazion. Epithelial changes: Associated hyperplasia of the ductal epithelium or glandular tissue may arise due to chronic irritation. Debris or keratin plugs may occasionally block the gland openings.[29][30] Differential Diagnoses Based on Histopathology Histopathology can help differentiate a stye from other conditions. A chalazion is characterized by granulomatous inflammation and macrophages with minimal acute inflammation. Sebaceous gland carcinoma presents with atypical sebaceous cells, high mitotic activity, and infiltrative growth patterns, and it may clinically mimic a recurrent stye or chalazion. Basal cell carcinoma is identified by nodular or infiltrative basal cell proliferation with palisading nuclei at the lesion margins. When to Perform Histopathology Histopathological analysis is warranted for persistent or nonresolving lesions despite standard therapy, recurrent lesions in the same location, and atypical presentations suggesting malignancy, such as lack of tenderness, abnormal pigmentation, or lash loss. While histopathology is rarely necessary for typical styes, confirming the diagnosis and identifying complications or malignancies in atypical or suspicious cases remains crucial.

History Patients with styes typically complain of a confined burning, tender swelling on one eyelid. Either the upper or lower lid may be involved (see Image. Lower Eyelid Hordeolum). In some cases, the complaint may start as generalized edema and erythema of the lid that later becomes localized. Patients frequently have a history of similar prior lesions of the eyelid. With an external hordeolum, pain, edema, and swelling are localized to a discrete eyelid area tender to palpation. The stye generally appears as a pustule with mild erythema of the lid margin. Pustular exudate may be present.[31] Given the relatively larger size of a meibomian gland, patients with an internal hordeolum present with more diffuse tenderness and erythema of the lid. Diagnosis may be made by everting the lid to reveal a small pustule on the conjunctival surface. When the gland is infected without obstruction, an internal hordeolum may appear similar to an external hordeolum. Treatment for internal and external hordeola is the same, so differentiation of the lesions is not of significant clinical importance.[32] In contrast to hordeola, chalazia have a more indolent and chronic presentation. Patients complain of nontender nodules of the eyelid with minimal to no surrounding erythema. In a persistent chalazion, chronic skin changes can develop around the underlying nodule.[33] Patients with a hordeolum typically present with the following: Chief complaint: Patients with an internal hordeolum commonly have localized swelling, redness, and tenderness of the affected eyelid. Pain is often described as mild to moderate and confined to the area of the lesion. Many also report a foreign body sensation or irritation in the affected eye.[34] Associated symptoms: Accompanying manifestations include tearing, also known as epiphora, or watery discharge. Sensitivity to light, or photophobia, may occur in some cases. Blurred vision can arise if the swelling mechanically disrupts the visual axis.[35]

Sensitivity to light, or photophobia, may occur in some cases. Blurred vision can arise if the swelling mechanically disrupts the visual axis.[35] Risk factors: Patients should be asked about contributing factors to internal hordeolum formation, such as poor eyelid hygiene, frequent eye rubbing, a history of blepharitis or meibomian gland dysfunction, and the use of eye makeup or contact lenses. Systemic conditions such as rosacea and diabetes mellitus also increase susceptibility. Weakened immunity due to stress or recent illnesses, such as an upper respiratory tract infection, can further predispose individuals to this condition. Chronicity: Establishing the onset of the condition is essential. The symptoms of an internal hordeolum are typically acute, lasting a few days to a week. However, recurrent episodes may indicate an underlying condition, such as chronic blepharitis or meibomian gland dysfunction.[36] Physical Examination A thorough eyelid and ocular examination often reveals the following findings: External inspection: Localized, red, and tender swelling is observed at the margin of the eyelid. An external hordeolum involves the glands of Zeis or Moll and appears as a superficial swelling near the lash line. An internal hordeolum involves the meibomian glands, presenting as a deeper swelling within the tarsal plate.[37] Palpation: The lesion is tender to touch and may feel fluctuant if pus is present. In cases of associated chalazion development, the lesion may feel firm upon palpation.[38] Examination of the conjunctivae and sclerae: Mild bulbar conjunctival injection, or redness, may be noted. Adjacent scleral areas are typically unaffected unless the infection has extended beyond the initial site.[39] Examination of the lid margin and gland openings: Signs of blocked meibomian gland openings or crusting may be observed, which is common in cases associated with blepharitis.[40]

Examination of the conjunctivae and sclerae: Mild bulbar conjunctival injection, or redness, may be noted. Adjacent scleral areas are typically unaffected unless the infection has extended beyond the initial site.[39] Examination of the lid margin and gland openings: Signs of blocked meibomian gland openings or crusting may be observed, which is common in cases associated with blepharitis.[40] Visual acuity: Visual acuity is typically normal unless mechanical ptosis or significant swelling interferes with the visual axis.[41] Regional lymphadenopathy: Mild preauricular lymphadenopathy may occur in cases of associated secondary infection, though it is rare.[42] Key differentiators include pain and tenderness, which are characteristic of styes and help distinguish them from a chalazion, which is painless and chronic. The acute onset of symptoms further sets styes apart from other chronic conditions, such as blepharitis and benign eyelid masses. By taking a detailed history and performing a focused physical examination, clinicians can confidently diagnose a stye and rule out other conditions that mimic its presentation.[43]

The evaluation of a stye is primarily clinical, relying on a detailed patient history and physical examination. However, additional diagnostic tests may be warranted in atypical or complicated cases to rule out other conditions or assess for complications. Below is a structured approach. Clinical Examination The primary diagnostic tool for styes is a careful clinical examination. History should include questions about the duration, pain, swelling, and any prior episodes. Risk factors such as eyelid hygiene, contact lens use, makeup practices, and any systemic conditions like diabetes or rosacea must be reviewed. During the physical examination, the eyelid must be inspected for a localized, tender, and swollen nodule. Look for signs of inflammation, including erythema, warmth, and purulent discharge. Also, evaluate for associated conditions like blepharitis or meibomian gland dysfunction.[44] Laboratory Tests Laboratory tests are rarely needed for uncomplicated styes but may be helpful in recurrent, atypical, or complicated cases. Microbiological testing is indicated if an atypical infection is suspected or the response to treatment is poor. Swabs from the lesion for gram stain and bacterial culture can identify causative organisms such as S aureus, and fungal cultures should be considered in immunocompromised patients.[45] Blood glucose or hemoglobin A1c (HbA1c) testing is recommended in patients with recurrent or severe styes to rule out undiagnosed diabetes.[46] A lipid profile may also be indicated in patients with recurrent chalazia or styes to assess for underlying dyslipidemia, which can contribute to meibomian gland dysfunction.[47] Imaging Studies Imaging is rarely required but may be useful in atypical or complicated cases. Ultrasound biomicroscopy may be helpful for evaluating deeper or atypical eyelid lesions when malignancy or abscess is suspected. Computed tomography (CT) or magnetic resonance imaging (MRI) is indicated when complications such as preseptal cellulitis and orbital cellulitis are suspected. CT with contrast is particularly valuable for differentiating between preseptal and orbital cellulitis.[48] Differential Diagnosis Assessment

Computed tomography (CT) or magnetic resonance imaging (MRI) is indicated when complications such as preseptal cellulitis and orbital cellulitis are suspected. CT with contrast is particularly valuable for differentiating between preseptal and orbital cellulitis.[48] Differential Diagnosis Assessment If a stye does not respond to typical treatment, additional evaluation may be necessary to rule out other conditions. For instance, sebaceous gland carcinoma may require a biopsy for a persistent or atypical lesion that fails to resolve with standard treatment. Additionally, chronic, nontender nodules could indicate a chalazion, which may need further assessment to confirm the diagnosis.[49] National and International Guidelines National and international guidelines provide a framework for the evaluation and management of styes to ensure effective diagnosis and treatment. The American Academy of Ophthalmology (AAO) recommends clinical evaluation as the primary method for diagnosing styes, reserving additional tests for atypical or recurrent cases. The Royal College of Ophthalmologists (RCOphth) suggests microbiological testing for cases with prolonged infections or poor response to antibiotics. The World Health Organization (WHO) emphasizes the importance of addressing underlying risk factors, such as hygiene and systemic conditions, to prevent recurrent styes.[50] Overall, adherence to these guidelines prioritizes patient safety, accurate diagnosis, and the prevention of complications.[51] Other Considerations Clinical examination suffices for the diagnosis and management of uncomplicated styes. For recurrent and atypical cases, laboratory tests (eg, cultures and glucose testing) and imaging (eg, CT and MRI) may be required.

For recurrent and atypical cases, laboratory tests (eg, cultures and glucose testing) and imaging (eg, CT and MRI) may be required. Differentiating a stye from a chalazion requires only a history and physical examination. No diagnostic tests are typically required or useful in their diagnosis. Colonization with noninvasive bacteria is common, and bacterial cultures of discharge from the area usually do not correlate with clinical improvement or aid in treatment. A recent chalazion may be challenging to differentiate from an internal hordeolum, but fortunately, management is the same.

Uncomplicated Hordeola A stye is usually a self-limiting condition, with resolution occurring spontaneously within a week. Internal and external hordeola are treated similarly. Warm compresses and erythromycin ophthalmic ointment applied twice a day are usually sufficient to hasten recovery and prevent the spread of infection. Little evidence demonstrates a benefit from topical antibiotics, but erythromycin ointment for 7 to 10 days has been recommended. Warm compresses should be applied for 15 minutes at least 4 times daily. Gentle massage of the nodule has also been suggested to assist in expressing the obstructed material. Oral antibiotics are rarely indicated unless significant surrounding erythema is present and periorbital cellulitis is a concern. Referral to an ophthalmologist is appropriate for very large hordeola, for which incision and drainage are considered. Reevaluation within 2 to 3 days is appropriate to assess treatment response.[52][53][54] Chalazia Conservative treatment is the mainstay of therapy for chalazia. Warm compresses and washing the affected eyelid with a gentle cleanser, such as baby shampoo, are usually the only measures required. Antibiotics are unnecessary since the etiology is inflammatory and not infectious. For cases that are recurrent or refractory to conservative treatment, combining intralesional corticosteroid injection with incision and curettage may be needed. These procedures necessitate referral to an ophthalmologist. Patients with chalazia should be referred to an ophthalmologist for nonurgent evaluation.[55] Severe or Persistent Styes Treatment for severe or persistent hordeola includes conservative measures, medical therapy, and surgical intervention. Below is a structured approach following both national and international guidelines. Conservative management

Below is a structured approach following both national and international guidelines. Conservative management For severe or persistent styes, conservative management remains the 1st-line approach. Applying a warm compress to the affected eyelid for 10 to 15 minutes, 3 to 4 times daily, helps promote drainage and relieve discomfort. The compress must be clean and not too hot to avoid burns. Maintaining eyelid hygiene by cleaning the eyelid margins with diluted baby shampoo or a commercial lid scrub can reduce debris and bacterial load. Patients should avoid touching or squeezing the lesion to prevent the spread of infection. Patients should also be advised to avoid using eye makeup and contact lenses while the infection has not resolved to prevent contamination and irritation.[56] Medical treatment Medical therapy is recommended for lesions that are moderate or associated with secondary infection. Topical antibiotics, such as erythromycin 0.5% or bacitracin, may be prescribed and applied 2 to 4 times daily to the eyelid margin to treat secondary bacterial infection. However, topical antibiotics are not always necessary for isolated styes.[57] Systemic antibiotics are indicated for preseptal cellulitis or widespread infection, with common choices including amoxicillin-clavulanate (500–875 mg orally twice daily) and doxycycline (100 mg orally once or twice daily). Doxycycline is also effective for associated meibomian gland dysfunction or rosacea.[58] Treatment typically lasts 7 to 10 days. Pain may be managed with over-the-counter analgesics, such as ibuprofen and acetaminophen.[59] Surgical intervention

Pain may be managed with over-the-counter analgesics, such as ibuprofen and acetaminophen.[59] Surgical intervention Surgical intervention is reserved for persistent or severe cases that do not respond to conservative or medical therapy. Incision and drainage may be performed by an ophthalmologist if the stye develops into an abscess or fails to resolve within 1 to 2 weeks. This procedure involves making a small incision to drain pus, offering immediate relief. For persistent lesions, particularly those evolving into chalazion, intralesional corticosteroid injection can be considered. Triamcinolone acetonide (0.05–0.2 mL of 10–40 mg/mL solution) can help reduce inflammation and expedite resolution. Recurrent Styes Addressing the underlying risk factors is important for patients with frequent recurrences. Long-term lid hygiene practices, such as regular warm compresses and cleaning, are essential for managing blepharitis or meibomian gland dysfunction. In chronic cases, low-dose doxycycline (eg, 20–40 mg once daily) may be considered. Rosacea should be managed with systemic antibiotics, such as doxycycline, and dietary modifications, including increased intake of ω3 fatty acids. For patients with diabetes, optimizing glycemic control is crucial to reduce the risk of infection. International Guidelines

For patients with diabetes, optimizing glycemic control is crucial to reduce the risk of infection. International Guidelines Standards for the proper treatment and prevention of styes improve the quality of care given to affected individuals and reduce unnecessary medical interventions. The American Academy of Ophthalmology recommends conservative measures as the 1st-line treatment and emphasizes the limited role of antibiotics for uncomplicated styes. The Royal College of Ophthalmologists advises that incision and drainage should only be performed if conservative management fails. The World Health Organization highlights the importance of hygiene and public education to prevent infections related to poor eyelid hygiene.[60] Key Points Important points to remember when caring for patients with hordeola include the following: Most styes resolve within 1 to 2 weeks with proper conservative care. Escalation to antibiotics or surgical intervention is warranted only in severe cases or those that fail the 1st-line treatment. Patient education on hygiene and risk factor management is critical to preventing recurrence. Styes can be effectively managed with minimal complications by adhering to this approach.

A stye presents as a localized, painful, red, and swollen lesion on the eyelid. Conditions that can mimic this clinical entity must be ruled out to ensure accurate diagnosis and management. Below is a list of key differential diagnoses. Chalazion: A chalazion is a chronic, nontender, firm nodule resulting from the blockage of a meibomian gland. Chalazia are typically painless and do not present with acute inflammation, which distinguishes them from styes, which are acute. Chalazia are chronic and often follow the resolution of a hordeolum. Preseptal cellulitis: Preseptal cellulitis is a bacterial infection of the eyelid and periorbital tissues anterior to the orbital septum. This condition is characterized by diffuse eyelid swelling, redness, and tenderness but lacks a localized nodule or abscess. Unlike chalazia, preseptal cellulitis does not present with a fluctuant nodule or pus discharge and may be accompanied by systemic symptoms such as a low-grade fever.[61] Orbital cellulitis: This severe bacterial infection affects the tissues posterior to the orbital septum. Orbital cellulitis is distinguished by significant proptosis, restricted extraocular movement, and vision changes. Systemic symptoms such as high fever and malaise often accompany this pathology, making immediate imaging and hospitalization essential. Sebaceous gland carcinoma: This rare but serious malignant tumor of the sebaceous glands often mimics a recurrent chalazion or hordeolum. Key differentiating features include a persistent or recurrent lesion that does not respond to appropriate treatment and the presence of eyelid margin abnormalities such as loss of eyelashes (madarosis). A biopsy is required for definitive diagnosis.[62] Blepharitis: This condition involves inflammation of the eyelid margin, often due to bacterial infection or meibomian gland dysfunction. Blepharitis is characterized by diffuse redness and scaling along the lid margins, often involving both eyes. This chronic condition is marked by irritation and crusting rather than acute painful swelling. Dermoid cyst: This congenital lesion is commonly found along the orbital rim. A dermoid cyst is distinguished by being painless and noninflammatory, presenting as a firm and well-circumscribed mass.[63]

Dermoid cyst: This congenital lesion is commonly found along the orbital rim. A dermoid cyst is distinguished by being painless and noninflammatory, presenting as a firm and well-circumscribed mass.[63] Dacryocystitis: This condition involves infection of the lacrimal sac following obstruction of the nasolacrimal duct. Dacryocystitis presents with swelling, redness, and tenderness localized to the inner corner of the eye near the lacrimal sac, often accompanied by tearing or purulent discharge.[64] Herpes simplex and zoster ophthalmicus: Herpes simplex is caused by the herpes simplex virus, while herpes zoster ophthalmicus arises from the reactivation of the varicella-zoster virus. These viral infections lead to inflammation of the eyelid. Herpes simplex is characterized by vesicles on the eyelid, while herpes zoster presents as a vesicular rash along the trigeminal nerve distribution, often accompanied by crusting and pain.[65] Molluscum contagiosum: This viral infection is caused by the molluscum contagiosum virus, presenting as dome-shaped, pearly papules on the eyelid. The lesions are painless and feature a central umbilication, distinguishing them from other conditions. Unlike styes and chalazia, molluscum contagiosum lesions do not show signs of inflammation or acute tenderness.[66] Accurate identification of the condition is essential to avoid inappropriate management, particularly with serious conditions like orbital cellulitis and sebaceous gland carcinoma, which require urgent treatment. When in doubt, referral to an ophthalmologist and additional investigations such as imaging or biopsy may be required. This structured approach ensures proper diagnosis and treatment while minimizing the risks of mismanagement.

Ongoing Studies Currently, radiation therapy is not recommended for the treatment of styes, as this condition is typically managed with conservative measures or minor surgical interventions. However, managing styes is the focus of various ongoing investigations. Topical and systemic antibiotics Topical and systemic antibiotics have shown promise in managing styes, with a study published in Ophthalmology demonstrating the effectiveness of topical erythromycin or bacitracin ointment in preventing secondary infections. Research continues to focus on developing new antibiotic formulations to improve treatment outcomes while minimizing side effects, particularly for patients experiencing recurrent styes.[67] Warm compresses and conservative measures Warm compresses and conservative measures remain a 1st-line approach for treating mild cases. Clinical guidelines, including those from the American Academy of Ophthalmology, emphasize their role in treating styes without the need for surgery. Studies indicate that conservative measures successfully manage over 70% of cases within 1 to 2 weeks.[68] Intralesional steroid injections Intralesional steroid injections, particularly with triamcinolone, have been shown in studies to effectively treat chalazia or chronic stye cases that do not respond to other treatments. The success rate for steroid injections is approximately 77%, and the procedure is associated with minimal recurrence.[69] Incision and drainage Surgical management, specifically incision and drainage, has proven effective for larger styes or abscesses that do not respond to conservative measures. Data indicate that surgical resolution rates exceed 90%, and complications are minimal when the procedure is conducted by experienced practitioners.[70] Studies on addressing underlying conditions and preventive care Treating underlying conditions, such as rosacea and meibomian gland dysfunction, has been supported by trials that demonstrate the benefits of long-term use of low-dose doxycycline or ω3 supplementation to reduce stye recurrence in patients with these associated conditions.[71] Preventive care studies emphasize the importance of maintaining proper lid hygiene to prevent stye recurrence, with findings supporting the use of commercial lid scrubs or diluted baby shampoo as effective measures.[72] Future Directions

Treating underlying conditions, such as rosacea and meibomian gland dysfunction, has been supported by trials that demonstrate the benefits of long-term use of low-dose doxycycline or ω3 supplementation to reduce stye recurrence in patients with these associated conditions.[71] Preventive care studies emphasize the importance of maintaining proper lid hygiene to prevent stye recurrence, with findings supporting the use of commercial lid scrubs or diluted baby shampoo as effective measures.[72] Future Directions For recurrent styes, ongoing studies are exploring the role of innovative modalities, such as laser-based heat therapies, in treating meibomian gland dysfunction, a common predisposing factor. For antibiotic stewardship, trials examine optimal antibiotic use to minimize resistance while maintaining efficacy in managing secondary infections.[73] Conclusion Although radiation therapy is not relevant to stye management, the evidence from existing studies underscores the importance of conservative measures, targeted antibiotics, and minor surgical interventions for effective resolution and recurrence prevention. These findings support current clinical guidelines for managing styes.

While hordeola are not traditionally staged in a formal classification system, the condition's progression may be understood in terms of clinical presentation and severity. Below is an informal staging system based on the progression of the disease. Early or initial stage (Stage 1): Early disease is characterized by mild localized redness, tenderness, and swelling along the eyelid margin. This stage arises from blockage and infection of the sebaceous glands (Zeis or meibomian glands) or hair follicles. Management typically includes warm compresses, lid hygiene, and observation, which are often sufficient for resolution. Progression or inflammatory stage (Stage 2): This stage is marked by increased redness and swelling, along with the formation of a small, tender, pus-filled nodule. Associated symptoms may include tearing, irritation, or mild pain. The inflammatory stage involves worsening inflammation and abscess formation within the infected gland. Management requires continuing with warm compresses. Topical antibiotics may be considered if the condition becomes severe or unresponsive. Advanced or complicated stage (Stage 3): The advanced stage presents with significant eyelid swelling and tenderness, as well as a persistent or enlarging lesion that may indicate secondary complications, such as preseptal cellulitis. This stage can lead to visual obstruction or discomfort due to mechanical ptosis. The pathophysiology involves chronic infection, abscess rupture, or deeper tissue involvement. Management may include incision and drainage along with systemic antibiotics if the infection spreads.[82] Resolution or chronic phase (Stage 4): The resolution or chronic phase is marked by a decrease in pain, swelling, and redness as the stye resolves. A chalazion may form in some cases. The pathophysiology in this stage involves the resolution of infection, potentially leading to scarring or gland dysfunction. For chalazion, management may include steroid injections or surgical removal if the nodule persists. While not formally staged, understanding the progression can guide treatment strategies and anticipate complications. Early intervention during stage 1 or 2 typically prevents progression to more severe stages. Clinicians can tailor their management approach to optimize outcomes and minimize complications by categorizing stye progression.[83]

The prognosis for a stye is generally excellent with appropriate management. Most cases resolve spontaneously or require only conservative treatment and do not produce significant complications. Short-term prognosis for styes varies depending on severity. Most uncomplicated styes resolve within 1 to 2 weeks with warm compresses and proper eyelid hygiene, and mild cases may not require additional medical treatment.[84] However, persistent or large styes may necessitate incision and drainage or topical antibiotics for resolution, with prompt treatment generally leading to favorable outcomes. To determine long-term prognosis, recurrence risk and potential complications must be considered. Patients with underlying conditions such as blepharitis, meibomian gland dysfunction, or rosacea face a higher risk of hordeolum recurrence, making long-term management strategies like lid hygiene and dietary changes (eg, ω3 fatty acids) crucial for prevention. While rare, unresolved styes can lead to complications such as chalazion formation or secondary infections like preseptal cellulitis or orbital cellulitis, which early treatment can help minimize. Chronic or recurrent cases may sometimes result in cosmetic concerns or eyelid scarring, which are typically managed with surgical correction. Key factors influencing prognosis include the following: Timeliness of treatment: Early intervention with conservative measures significantly improves outcomes and prevents complications. Patient compliance: Adherence to hygiene practices, warm compresses, and follow-up care ensures better resolution rates and fewer recurrences. Underlying conditions: Proper management of systemic or eyelid-related factors, such as diabetes or chronic blepharitis, enhances the overall prognosis. In summary, most patients fully recover without any lasting effects with appropriate care. Long-term outcomes depend on addressing acute issues and predisposing factors to prevent recurrence.

Complications that may arise from a hordeolum include the following: Chalazion formation: If a stye does not resolve completely, it may evolve into a chalazion, a chronic, nontender nodule resulting from blocked meibomian glands. Chalazia often require surgical intervention for resolution.[85] Preseptal cellulitis: The spread of infection to the surrounding soft tissues of the eyelid can lead to preseptal cellulitis, a condition characterized by redness, swelling, and tenderness of the eyelid. This condition requires systemic antibiotics to prevent progression.[86] Orbital cellulitis: Rarely, untreated or severe infections can extend beyond the orbital septum, leading to orbital cellulitis, a potentially life-threatening condition requiring immediate hospitalization, intravenous antibiotics, and possibly surgical drainage.[87] Recurrent styes: Recurrences may occur due to underlying conditions such as blepharitis, meibomian gland dysfunction, or systemic conditions like diabetes mellitus. Frequent episodes can lead to patient frustration and a need for long-term management. Corneal involvement: Prolonged eyelid inflammation can irritate the cornea, causing keratitis or corneal abrasions, which may impair vision and require additional treatment.[88] Scarring and cosmetic concerns: Multiple recurrences or improperly managed infections can cause eyelid scarring or deformities, which can impact the patient’s appearance and require surgical correction.[89] Prompt treatment with warm compresses and lid hygiene can prevent escalation. Close monitoring and early medical or surgical intervention for persistent or worsening cases can reduce the risk of severe complications. Addressing underlying conditions (eg, blepharitis, diabetes) and lifestyle factors (eg, makeup hygiene and contact lens use) is essential for minimizing recurrences. By recognizing and managing complications early, healthcare providers can improve outcomes and prevent more serious consequences associated with styes.

When to Consult an Ophthalmologist Indications for consulting an ophthalmologist for a hordeolum include the following: Recurrent or persistent styes: A consultation with an ophthalmologist is recommended if the stye does not resolve with conservative treatments such as warm compresses and lid hygiene after 1 to 2 weeks. Recurrent styes may indicate underlying conditions such as meibomian gland dysfunction, blepharitis, or systemic conditions like rosacea or diabetes.[96] Suspected complications: Signs of preseptal cellulitis or orbital cellulitis, including worsening redness, swelling, fever, or pain with eye movement, require immediate referral for systemic antibiotic therapy or further evaluation. Suspected chalazion formation or deeper abscess may require incision and drainage by an ophthalmologist.[97] Vision impairment: A specialist consultation is necessary if the stye causes significant visual disturbance due to mechanical ptosis or corneal involvement.[98] Atypical presentations: Cases with unusual features, including the lack of response to treatment or abnormal growth, warrant a referral to rule out more serious conditions like sebaceous gland carcinoma or other neoplastic processes.[99] Role of Other Specialists Other medical professionals that may be involved in the care of patients with hordeola include, but are not limited to, the following: Dermatologist: A dermatologist may help patients with conditions like rosacea or chronic blepharitis manage systemic skin-related factors contributing to styes.[96] Endocrinologist: Patients with poorly controlled diabetes may benefit from endocrinology consultation to address systemic factors that increase the risk of recurrent infections.[100] Primary care physician: Collaboration with the patient’s primary care physician may be necessary to address systemic conditions or risk factors contributing to recurrent styes. Interprofessional Collaboration Ophthalmologists, primary care providers, and specialists, such as dermatologists and endocrinologists, should work together to ensure comprehensive patient management, addressing both local and systemic factors that may contribute to stye development and recurrence. This collaborative approach ensures prompt and effective care while preventing complications or recurrences.

Deterrence Strategies Measures that can help prevent hordeolum formation include the following: Eyelid hygiene: Clinicians should educate patients on the importance of regular eyelid cleaning using diluted baby shampoo or commercial lid scrubs to prevent blockages in meibomian glands. Providers should reinforce the necessity of thorough hand washing before touching the face or eyes.[101] Avoidance of sharing personal items: Patients must be advised against sharing towels, washcloths, or makeup products to minimize the risk of bacterial contamination.[102] Replacement of old eye makeup: Providers should recommend disposing of eye makeup every 3 to 6 months to prevent bacterial buildup. Proper contact lens hygiene: The importance of cleaning and disinfecting contact lenses and adhering to replacement schedules should be stressed. Overnight lens wear, unless prescribed for specific therapeutic reasons, must be discouraged.[103] Addressing predisposing factors: Providers must discuss managing conditions like blepharitis, rosacea, or meibomian gland dysfunction, which can predispose patients to recurrent styes. For patients with diabetes, the importance of glycemic control in reducing the risk of infections should be highlighted. Patient Education Other important points to emphasize when counseling patients with hordeola include the following: Self-care instructions: Clinicians should teach patients the benefits of warm compresses (3–4 times daily) to alleviate symptoms and facilitate drainage. They should also explain how gentle lid massage after compresses can promote gland function.[104] When to seek medical care: Patients should be instructed to seek immediate care under the following circumstances: The stye does not resolve within 1 to 2 weeks. Worsening pain, swelling, or redness is present, which may indicate complications like preseptal cellulitis or a deeper infection. Vision changes or systemic symptoms like fever develop.[105] Lifestyle modifications: Providers may suggest dietary supplementation with ω3 fatty acids to support meibomian gland health. They should also encourage patients to stay hydrated and maintain a balanced diet for overall eye health.[106] Compliance and long-term prevention: Adherence to preventive measures and follow-up care must be reinforced, especially in patients prone to recurrent styes.

By addressing prevention and education, patients can effectively reduce the risk of styes and manage symptoms promptly, ensuring improved outcomes and fewer recurrences.

Other Issues Although it occurs uncommonly, an untreated stye may evolve into localized cellulitis of the eyelid and surrounding skin. Periorbital, or rarely, orbital cellulitis, may ensue if the infection is allowed to progress. Any worsening erythema and edema beyond a localized pustule should be monitored closely for cellulitis, which may require systemic antibiotics. For infections that are not well localized, blood tests, including a complete blood count with differential and blood cultures, may be needed. An orbital CT scan may be ordered if orbital cellulitis is suspected.[107] Blepharitis is a related condition involving inflammation of the eyelid margin characterized by erythematous, pruritic eyelids, conjunctival injection, crusting or matting of the eyelids, and occasionally flaking of the eyelid skin. In contrast to hordeolum and chalazion, blepharitis should not have a discrete nodule within the eyelid. Treatment involves warm compresses and gentle washing of the eyelids with warm water or diluted baby shampoo. If these attempts are unsuccessful, a topical antibiotic such as erythromycin may be tried.[108] Pearls The most important points to remember when managing styes include the following: Early intervention: Warm compresses applied 3 to 4 times daily can help resolve most styes without invasive intervention. Compliance with this simple measure is crucial. Lid massages following warm compresses can assist in draining clogged glands.[109] Hygiene focus: Eyelid hygiene is a cornerstone of prevention and management. Regular use of diluted baby shampoo or commercial lid scrubs is recommended to clean the eyelid margins. To prevent exacerbation, patients should be educated about avoiding makeup or contact lenses during an active stye. Associated conditions: Consider evaluating for underlying conditions such as blepharitis, meibomian gland dysfunction, or rosacea, which can predispose patients to recurrent styes. Patients with diabetes are at higher risk of infections and may require more aggressive management.[110] When to refer: Persistent or recurrent styes despite treatment should prompt referral to an ophthalmologist. A suspected chalazion, preseptal cellulitis, or deeper orbital involvement requires further evaluation and possible surgical or systemic therapy.[111]

A suspected chalazion, preseptal cellulitis, or deeper orbital involvement requires further evaluation and possible surgical or systemic therapy.[111] Disposition: Most styes are self-limiting and resolve within 1 to 2 weeks with conservative management. Severe cases with significant swelling, pain, or recurrent episodes may require incision and drainage or intralesional corticosteroid injection by an ophthalmologist.[112] Pitfalls Differentiating between a stye and a chalazion is critical. While a stye is an active infection with tenderness, a chalazion is a chronic, nontender inflammatory lesion. Failure to recognize preseptal cellulitis or orbital cellulitis may delay critical systemic antibiotic therapy. Routine antibiotic use is unnecessary for uncomplicated styes. Overprescription contributes to antibiotic resistance. Antibiotic ointments, if used, should target the specific bacterial pathogens typically associated with styes, most commonly Staphylococcus aureus. Patients often discontinue compresses too soon. The need for consistent application over several days for effective resolution must be reinforced. Prevention Patients must be educated on proper hand hygiene, especially before touching the face or eyes. Patients should be instructed to avoid sharing towels, pillowcases, or makeup products that may harbor bacteria.[113] Proper lens hygiene and replacement schedules must be emphasized to minimize bacterial contamination. Patients should avoid wearing lenses overnight unless explicitly advised.[114] Patients should address environmental irritants such as dry or dusty air, which can exacerbate gland dysfunction. A balanced diet with ω3 fatty acids is recommended to promote healthy meibomian gland function.

A hordeolum may be encountered by the emergency department physician, nurse practitioner, internist, or primary care provider. Most styes may be managed conservatively by these healthcare professionals, but if the diagnosis is doubtful, the patient should be referred to an ophthalmologist. Styes respond rapidly to warm compresses and erythromycin ointment. However, the patient must be seen again within 48 to 72 hours to ensure healing. The outcomes for most individuals with a stye are excellent.[115] Effectively managing a stye requires a collaborative, patient-centered approach involving various healthcare professionals. This teamwork ensures improved patient outcomes, enhanced safety, and optimized care delivery. Below are the key aspects:[116] Skills and Strategy Effective management of styes relies on diagnostic accuracy, tailored treatment strategies, and coordinated care. Physicians and advanced practitioners should use clinical judgment to distinguish styes from similar conditions like chalazion and preseptal cellulitis. Treatment involves educating patients on warm compresses, lid hygiene, and the appropriate use of antibiotics or incision and drainage when necessary. Nurses and ophthalmic technicians support noninvasive care by providing daily care instructions and emphasizing adherence to reduce recurrence. Ethics and Responsibilities Ethical management of styes requires informed consent, equitable access, and patient advocacy. Patients should be fully informed about treatment options, including conservative management, procedural interventions, and potential risks. Efforts must be made to ensure accessible and affordable care, particularly in underserved populations where recurring styes may result from inadequate hygiene or limited resources. Pharmacists and nurses play a key role in advocating for affordable medications or suggesting over-the-counter alternatives when prescriptions are not financially feasible.[117][118] Interprofessional Communication

Pharmacists and nurses play a key role in advocating for affordable medications or suggesting over-the-counter alternatives when prescriptions are not financially feasible.[117][118] Interprofessional Communication Effective interprofessional communication is essential for managing styes. Physicians and nurses collaborate to implement warm compress protocols, while pharmacists provide guidance on the proper use of topical antibiotics or oral medications and ensure no contraindications or allergies are present. Referral coordination is critical, with advanced practitioners or general physicians directing patients with recurrent or atypical styes to ophthalmologists. Detailed documentation of treatment plans and follow-ups ensures continuity of care across the healthcare team.[119] Care Coordination Care coordination focuses on tailoring interventions to individual patient needs, considering factors like lifestyle, occupation, or underlying conditions such as diabetes and rosacea. Regular follow-ups are essential to monitoring unresolved styes and identifying complications like abscess formation or deeper infections that may require surgical intervention. Preventive strategies, including proper eyelid hygiene, avoiding makeup during active infection, and replacing contaminated contact lenses, should be emphasized by all members of the healthcare team.[120] Outcomes, Patient Safety, and Team Performance Coordinated care leads to improved outcomes, including faster symptom resolution, fewer complications, and reduced recurrence rates. Shared decision-making enhances patient safety by preventing the overuse of antibiotics and avoiding unnecessary surgical interventions. Interprofessional reviews for complex or recurring cases optimize team performance by refining protocols and enhancing care delivery.
