Hi jaz,
I bet you were scared, I know I would be. Complete blindness can be a symptom of Retinal Migraine (Retinal Migraine - The Basics) and is fully reversible after the Migraine is over. But here's the thing - one of the most important things you can do is to get an accurate diagnosis. To simplify matters and make it easier for people to get information and treatment, doctors usually go by the gold standard for diagnosis, the International Headache Society's International Classification of Headache Disorders, 2nd Edition (ICHD-II). Under ICHD-II, there is no diagnosis of "ocular" Migraine. We do see it used, but doctors use it differently, so it really doesn't tell anyone what type of Migraine you actually have. You can read more about this in Ocular, Optical, and Opthalmic Migraines and The Type of Migraine Does Matter.
Research is now showing that Migraine may be a progressive brain disease. We have an article you can continue reading: Migraine with Aura Linked to Late-Life Brain Lesions.
We do have a Migraine specialist in Cheyenne, WY you may want to look into. Some states don't even have one specialist, so in that respect I guess you are lucky You can see our patient recommended Migraine specialist directory HERE.
I hope this helps.
