Arterial insufficiencies: Central retinal artery occlusion

Central retinal artery occlusion (CRAO) is a relatively rare emergent condition of the eye resulting in sudden painless vision loss. This vision loss is usually dramatic and permanent, and the prognosis for visual recovery is poor. A wide variety of treatment modalities have been tried over the last 100 years with little to no success, with the exception of hyperbaric oxygen therapy. The optimum number of treatments will vary depending on the severity and duration of the patient’s symptoms and the degree of response to treatment. The majority of patients will stabilize within a few days after symptom onset. Utilization review is recommended for patients treated for more than three days after clinical plateau.
