Everything You Need to Know About Retinal Artery Occlusion


A retinal artery occlusion is a blockage in one or more of the arteries of your retina. Read on to learn about this condition, its symptoms and treatment options.


What Is Retinal Artery Occlusion?

Retinal artery occlusion happens when a blockage occurs in one or more of the arteries in the retina. It is caused by a clot or a build-up of cholesterol in an artery.

There are two different types of retinal artery occlusions: Central retinal artery occlusion (CRAO) and branch retinal artery occlusion (BRAO). CRAO refers to a blockage in the central artery in the retina. BRAO blocks the small arteries in your retina. Both are forms of stroke in the eye.

Retinal Artery Occlusion Symptoms

What Are the Symptoms of Retinal Artery Occlusion?

The most common symptom of retinal artery occlusion is sudden and painless vision loss. In the case of central retinal artery occlusion, it affects the entire retina of one eye; in the case of branch retinal artery occlusion, it affects parts of the retina of one eye.

Other symptoms of retinal artery occlusion include blind spots, distorted vision, and loss of peripheral vision. People with this condition must seek a specialist’s care to prevent vision loss, stroke and/or heart attack.
