Visual MigraineVisual Migraine
A visual migraine, or [Opthalmic Migraine]?Create, is the result of a vasospasm, a spasm of arteries behind the eye, resulting in blood flow being shut off to the optic nerve.
Visual Migraine is a partial blindness that comes on often with no warning. It is a graying out, sometimes involving bright spots or flashing lights, not a blacking out of the vision, and it is partial, not total blindness. Episodes usually last from 10-40 minutes, but hers were almost always a minimum of 40 minutes up to nearly 50 minutes. It is a neurological problem, not an eye problem.
Visual migraines may also be caused as a stress reaction, although some think it could be an allergic reaction.
People who see flashes of lights that appear as jaggaed lines or “heat waves” lasting 10-20 minutes, may be caused by a spasm of blood vessels in the brain, called migraines. If a headache follows the flashes, it is called a migraine headache. Sometimes these symptoms may occur with or without a opthalmic migraine.
