Hello, I'm an expert in medical science with a focus on ophthalmology. I can provide you with information on the topic you're asking about.
A stroke typically refers to an event in the brain where there's a loss of blood supply, either due to a blockage or a rupture in a blood vessel. However, the term "stroke" can sometimes be used metaphorically to describe similar events in other parts of the body, including the eye.
In the eye, a condition that is often referred to as an "ocular stroke" is more accurately known as an occlusive vascular event. This can happen when the blood supply to the retina, the light-sensitive tissue at the back of the eye, is interrupted. There are two main types of these events:
1. Arteriolar Occlusion: This is when a small artery that supplies blood to the retina becomes blocked. It can occur due to a blood clot or other embolus (a particle that moves through the blood).
2. Venous Occlusion: This happens when a vein that drains blood from the retina is blocked, often leading to swelling and bleeding in the retina.
While these conditions are not technically "strokes" in the same sense as a cerebral stroke, they can have serious consequences for vision and are considered medical emergencies.

A branch retinal artery occlusion usually occurs suddenly. While typically painless, a BRAO can cause an abrupt loss of peripheral vision. In some cases, you may also lose central vision. If you have sudden vision loss or other symptoms of an "eye stroke," see your doctor immediately.
