Central retinal artery occlusion (CRAO) is a vascular ophthalmic emergency. Often caused by a sudden interruption of blood flow to the eye, with profound and painless vision loss, resulting in irreversible cell damage. An impacted embolus at the narrowest part of the central retinal artery is the most common cause.

Cardioversion is a medical procedure used to restore a normal heart rhythm in individuals with atrial fibrillation (AF). In some cases, cardioversion can lead to thromboembolic complications. If an embolus reaches the central retinal artery, it can block the blood flow to the retina, resulting in CRAO and subsequent vision loss.
