While most people think of strokes affecting the brain, they can also affect the eye. Central retinal artery occlusion (CRAO) is a rare form of acute ischemic stroke that occurs when blood flow is blocked to the main artery of the eye. It typically causes painless, immediate vision loss in the impacted eye, with fewer than 20% of people regaining functional vision in that eye.
The American Heart Association published a new scientific statement, “Management of Central Retinal Artery Occlusion,” in Stroke, an American Heart Association journal. The American Association of Neurological Surgeons/Congress of Neurological Surgeons Cerebrovascular Section affirms the educational benefit of the scientific statement, and it has been endorsed by the North American Neuro-Ophthalmology Society, the American Academy of Ophthalmology Quality of Care Secretariat and the American Academy of Optometry.
