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.
Causes of retinal migraine. Retinal migraine is caused by the blood vessels to the eye suddenly narrowing (constricting), reducing the bloodflow to the eye. Afterwards the blood vessels relax, bloodflow resumes and sight returns. Usually there are no abnormalities within the eye and permanent damage to the eye is rare.
