Central Retinal Artery Occlusion

Purpose of ReviewThis review aims to provide a comprehensive overview of emergency department management of central retinal artery occlusion (CRAO). It examines common presentations, etiologies, workup, and various treatment options with their evidence.Recent FindingsThere is limited research on CRAO. Most treatment methods and guidelines are based on observational literature, case series, retrospective studies, and expert opinion. Many of the treatments available to the emergency provider have limited success. More advanced treatments with hyperbaric therapy or thrombolytics are becoming more established.SummaryWorkup for CRAO should focus on establishing the etiology of the event. There are many treatment options available to the emergency provider, including emergent hyperbaric oxygen therapy and thrombolytics. Emergency department care should occur in conjunction with ophthalmology and neurology. Much of the treatment is guided towards preventing future cardiovascular events.
