Central retinal artery occlusion

Central retinal artery occlusion usually presents as a sudden onset of painless and profound visual loss. The condition may be preceded by episodes of transient visual loss. The cause of central retinal artery occlusion is most commonly emboli from the carotid artery or the heart. This patient is showing an unusual sparing of the papillomacular nerve fiber bundle due to a patent cilioretinal artery. Approximately 1 in 4 patients with central retinal artery occlusion have significant carotid artery disease, cardiac valvular disease, or diabetes. (Contributed by Dr. Rosa Tang.)
