Imaging plays an important role in the diagnosis and management of trauma to the eye. In addition to computed tomography, which is the primary imaging modality used for orbital trauma, ultrasound and optical coherence tomography are less-invasive techniques to assess the structures of the eye. This activity reviews the imaging techniques used in the setting of trauma to the eye and orbit. It describes the key findings for various vision and life-threatening conditions, including orbital fractures, foreign bodies, open-globe injuries, retinal detachment, and anterior-segment injuries. Objectives: Describe the imaging techniques indicated for various settings of trauma to the eye and orbit. Review the anatomy of the eye and orbit, focusing on the most commonly implicated structures in orbital trauma. Summarize key findings that may be seen on imaging in patients with a history of orbital and ocular trauma. Explain the appropriateness of imaging techniques used by the interprofessional team in various situations, such as ocular foreign body and open-globe injuries.

Trauma to the eye makes up 3% of all emergency department visits in the United States.[1] Imaging plays a key role in medical diagnostics, decision-making, and treatment planning for ocular trauma. The use of imaging for eye complaints in the emergency setting has increased significantly over the past two decades.[2][3] Knowing when to order a test and how to interpret the results is important for patient outcomes and cost-effectiveness. This article will discuss the anatomy of the eye and orbit, common imaging modalities used to assess the relevant structures, findings of commonly seen pathology, and the indications and reasoning behind each test.
