Eye Stroke Care

Similar to some strokes caused by blockages in blood vessels in the brain, an eye stroke is caused by a blockage, typically a blood clot, in an artery in the eye. 

A blockage in the main artery in the retina is called a central retinal artery occlusion (CRAO). A blockage in a smaller artery is called a branch retinal artery occlusion (BRAO).

Because these arteries are responsible for supplying blood to the eye, a lack of blood flow can affect your vision. Without quick intervention, you may experience permanent vision loss or blindness.

The hallmark signs of eye stroke are sudden and painless vision loss or changes in vision -- like blurriness, floaters, a darkened area in your field of vision, decreased visual contrast, and light sensitivity -- in one eye. Although these symptoms usually come on quickly, they can appear gradually.

To definitively diagnose an eye stroke, an ophthalmologist performs an eye exam in person or reviews a special picture called a fundus photo, which images the internal parts of your eye, including the optic nerve and retina. Diagnosis should be done as soon as possible in an emergency department. 

Assessing Stroke Risk and Coronary Artery Disease Risk 
An eye stroke can increase your risk of brain stroke, and vice versa. A vascular neurologist -- a neurologist who specializes in stroke care -- will evaluate your risk factors for a future stroke. Your doctor will consider your blood pressure, cholesterol levels, weight, diet, exercise habits, whether you have diabetes or arrhythmias, and your personal and family history, among other factors.

Imaging Tests
A vascular neurologist or cardiologist may also recommend that you undergo an ultrasound or other imaging to determine whether you have or are at risk for carotid artery disease or heart disease.

Eye Care
Optometrists, ophthalmologists, or retinal specialists can treat or help prevent complications like retinal disease that can affect your eyes and vision after an eye stroke.
