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.
The cause of migraine with aura isn't clearly understood. It's believed that the migraine with visual aura is like an electrical or chemical wave that moves across the part of your brain that processes visual signals (visual cortex) and causes these visual hallucinations.
