what is an eye stroke and what causes it

Eye strokes occur when blockages (occlusions) occur in arteries or veins in the retina, causing vision loss. The severity of vision loss depends on the extent and location of the occlusion(s) and loss of blood flow.

Just as strokes occur in other parts of the body because blood flow is blocked, your eye also may suffer damage when vital structures such as the retina and optic nerve are cut off from nutrients and oxygen flowing through your blood.

Besides having an eye exam to detect signs of an eye occlusion, you’ll also need your family doctor or internal medicine physician to evaluate you for high blood pressure, artery disease or heart problems that may be responsible for the blockage.

If a blockage is found, the type of retinal artery or vein occlusion you have is categorized by its location
