While most people think that strokes affect only the brain, they can also affect the eye. Central Retinal Artery Occlusion (CRAO) is a rare form of acute stroke that occurs when blood flow is blocked to the main artery of the eye. It typically causes painless, immediate vision loss, and fewer than 20% of those affected regain functional vision in the impacted eye. Because eye strokes are less common, they are often not diagnosed quickly, and often not referred for emergency care. While there is uncertainty in the medical community as to exactly what causes CRAO, and the best way to treat it, CRAO can be a warning sign of future brain strokes and heart attacks. As a potential early indicator for these vascular events, anyone experiencing CRAO should undergo urgent screening and treatment for cardiovascular risk factors.
