When one of the vessels that carry blood to your eye’s retina gets blocked, it can cause you to lose your eyesight. This problem often happens suddenly and without any pain. This is called a central retinal artery occlusion (CRAO).
Context Explanation
Central retinal artery occlusion (CRAO) is an ocular emergency. Patients typically present with profound, acute, painless monocular visual loss—with 80% of affected individuals having a final visual acuity of counting fingers or worse. Central retinal artery occlusion (CRAO) is a disease of the eye where the flow of blood through the central retinal artery is blocked (occluded). There are several different causes of this occlusion; the most common is carotid artery atherosclerosis.

Insight Material
Central retinal artery occlusion (CRAO) and branch retinal artery occlusion (BRAO) present with acute, painless loss of monocular vision. Patients with central retinal artery occlusion (CRAO) complain of visual loss over the entire field of vision, while those with a branch retinal artery occlusion (BRAO) complain of hemifield defect. A blockage in the main artery in the retina is called central retinal artery occlusion (CRAO), which often results in severe loss of vision. However, about 25% of people who develop CRAO have an extra artery called a cilioretinal artery in their eyes. Central retinal artery occlusion (CRAO) has been known as a clinical entity since 1859, when von Graefe [1] first described CRAO due to embolism.

After that, Schweigger [2] in 1864 described it on ophthalmoscopy. It is an ophthalmic emergency because of instant, massive visual loss. Central retinal artery occlusion (CRAO) is a form of acute ischemic stroke that causes severe visual loss and is a harbinger of further cerebrovascular and cardiovascular events.
