I have heard of those visual auras being a migraine without the headache...occular migraines. I haven't had them, so I am not so familiar with them. Sorry you are having them more frequently, is the Topamax/Topiramate helping? I always have headache. In fact, I have had a headache every single day for as long as I can remember. I call it a baseline headache, it is always there and at times it gets much worse or I get a migraine. I cannot remember a day that I didn't have one. I have been getting migraines since I was a kid and I am 47 now. Topamax changed my life

I am with you on the flashing/blinking lights. They will trigger a migraine instantly....strobe lights are the worst!

I just went up to the 100mg of Topiramate with the split 50/50 dosage so am hoping it helps. At 75mg only in PM I had 3 more visual auras in a cluster after only 25 days in- between. So right now I am in a lull. I am hoping this works better to spit the dosage and keep it more even in my blood stream. When they did the EEG 10 yrs ago with the Flashing Lights trying to trigger a seizure, it was so terribly painful [the strobe lights that is]. I had a "bad-for-me" headache for 2 + weeks afterwards - anyone else probably would have thought it was "moderate". Recently, I had another EEG done without the Strobe lights, and it didn't show the brain waves with spikes like that first one. I'm sure it was the strobe lights that did it! This EEG was normal.
