Retinal migraine. Retinal migraine (also known as ophthalmic migraine, and ocular migraine) is a retinal disease often accompanied by migraine headache and typically affects only one eye. It is caused by ischaemia or vascular spasm in or behind the affected eye.
Retinal migraine (ocular migraine) is an eye condition that causes brief attacks of blindness or visual problems like flashing lights in one eye. These episodes can be frightening, but in most cases they're harmless and shortlived, and eyesight goes back to normal afterwards.
