I have had opthalmic migraines off and on for 18 years - had the first one during my first pregnancy (VERY scary). I can go years without one, than have 5 in a week. Doctors have said not to worry, no MRI. Triggers can be stress, chocolate, hormones etc. - all the typical triggers for many things. Aside from causing anxiety, the strangest part for me is that I can still see the patterns with my eyes closed.
