Gardenpeace,
I think your dr is right in saying it's eye migraine, or also called a migraine aura. I had it the first time this summer, and am dealing with it now about 4 times a week, together with cluster headaches (stabbing pain in 1 eye). My neurologist says they are like brother and sister, they often come together.
When I feel it coming up while driving (I never think of it, it starts by rubbing my eyes cause I feel something is covering them, and then it starts full force, sometimes switches from one eye to the other halfway) I need to pull over and wait for about 45 minutes for it to go away. Driving while have an aura is suicide.
I tried Topamax, but I had too many side effects, now I will be trying Propranolol. It lowers blood pressure, and works like a betablokker (confirmed by my neurologist this morning), so not suitable for everyone.
For the other posters: aside from the above, I have floaters (MANY of them), blurred vision, after-images, flashing lights in peripheral vision (half moons passing by, or white waves in the corners of my eyes), pressure on eyeballs. I'm severely myopic, and get my eyes tested every year, and the dr says that they are in great condition, apart from the fact that I'm almost blind
