MY MOM USED TO SEE ZIG ZAG LINES (SEMI CIRCLE)IN HER VISION. SHE IS TAKING MEDICINE FOR HIGH BLOOD PRESSURE. IS THAT DUE TO BLOOD PRESSURE?
Its not your medication. Use the search feature and searach "TIA and transient ischemic attack" and "eye migraines and ophthalmic migraine".
Your problem could be due to disease of the eye, brain, heart or blood vessels. Only after these have been excluded can it be called an Eye Migraine (which don't have headaches).
