um, yes. there are things you can do. medications (like topamax, etc) to prevent the onset of migraines. you need to be talking to your primary care physician or neurologist. this is not an "eye" problem...
Are there things I can do to avoid or minimize the impact of these? I can't identify any common trigger, except for general stress level. I do expereince regular migraines that last over several days and do not respond to OTC pain medications.
I am less concerned after this response, but if it were to reoccur while driving that would be pretty scary!
YES. ocular migraine. classic ocular migraine symptoms. very UNlikely to be any retinal problem that you need to have checked out.
