Question: What is an eye stroke?
Answer: According to Dr. Eleanor E. Faye, M.D., FACS, “The term “eye stroke” is misleading. The word “stroke” in diagnosing such an eye condition is not scientific and has other connotations related to brain activity that are scary to a lay person. Some ophthalmologists use the term as a simple (and I think misleading) diagnosis for an occlusion of a major eye vessel.
blood clot or spasm of a vessel in the eye cuts off the blood supply and causes the retinal area fed by that vessel to die off, which leads to loss of vision in that part of the retina.
Most eye vessel occlusions are secondary to hypertension or some blood dysfunction. That means the person needs to see a medical doctor, have his or her blood pressure checked and have some blood studies done to rule out a blood clotting disorder or some other blood problem such as leukemia. The occlusion is usually permanent but rarely results in total blindness. It is usually unilateral as well and has no other systemic effects (unlike a stroke in the brain).”
