While this is one of the best Migraine sites I've seen so far, it does not say more than a cursory mentioning of retinal migraine which is disappointing. Still, it gives a good listing of symptoms of Retinal Migraine that is hard to find elsewhere. This is an audio/visual presentation by a drug company, but is quite thorough and extremely well-done in an entertaining english-type accent. No doubt if it was as thorough with retinal migraine as with headache in general, I would have eagerly given it a 5 star standing ovation.
