Central Retinal Artery Occlusion and Branch Retinal Artery Occlusion
Prognosis
Patients with a branch artery occlusion may maintain good to fair vision, but with central artery occlusion, vision loss is often profound, even with treatment. Once retinal infarction occurs (as quickly as 90 minutes after the occlusion), vision loss is permanent. If underlying giant cell arteritis is diagnosed and treated promptly, the vision in the uninvolved eye can often be protected and some vision may be recovered in the affected eye.
