Sudden vision loss without pain is the most common symptom of a stroke involving your eye. An eye stroke, or anterior ischemic optic neuropathy (AION), is a condition in which blood flow either becomes blocked or reduced to the tissues of the front part of the optic nerve

An eye stroke can cause sudden loss of peripheral vision, distorted vision, and blind spots in your vision, and while it may be frightening, prompt medical attention can prevent or limit vision loss.

Eye stroke is caused by poor circulation in the blood vessels that supply the front portion of the optic nerve. The optic nerve is the cable that connects the brain to the eye and carries millions of nerve fibers and blood vessels.

Although an eye stroke can occur from a total blockage of a blood vessel that feeds the optic nerve, it is more commonly caused by a lack of pressure or perfusion of the tissue. Blood pressure may change relative to the eye pressure and the normal flow of blood is reduced.

If the optic nerve’s nutrient and oxygen supply are cut off, nerve tissue is damaged and lost, resulting in vision loss.

Whenever you experience sudden blindness or any sudden loss of vision, you need to see an eye specialist straight away. Treatment will depend on the cause, but in most cases the earlier you are treated, the better your chance of a good outcome.
