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.
Regular migraines can also cause vision problems, called an aura, which can involve flashing lights and blind spots in your vision. But these symptoms usually appear in both eyes. See your doctor to find out if you have ocular migraines. He can rule out other conditions that can cause similar symptoms.
