title: Visual disturbances in migraine.
abstract: Abnormal visual sensations are the most common and characteristic features of migraine. In some patients, they are the only features. The major visual disturbance associated with migraine is scotoma; less common are distortions in size, shape, and color of viewed objects; photophobia; and diplopia and polyopia. Sudden loss of vision occurs in retinal migraine, and paralysis, usually of the third nerve, in ophthalmoplegic migraine. Paresis also may be found with cluster headache.
