Is this an ocular migraine?

Patient: Hi. A few years ago I got a blind spot on one eye and was told it was because of a migraine. Tonight, I saw flashing lights in my left eye that turned into colored flashing zig zags. I believe this is an ocular migraine but I just want to make sure that it may not be something else. Thank you

Symptoms: Flashing colored zig zag lines in left eye with light headedness

Doctor:
