—The multitude of signs and symptoms in migrainous vasculopathy ranges from the common visual prodromes and transient hemicephalic syndromes of cephalgia with sensory and motor losses to the permanent sequelae of complicated migraine.1 The latter may be due to retinal or optic nerve ischemia; more commonly, there is compromise of the posterior circulation of the brain, producing cortical ischemia and hemianopia. Permanent monocular impairment of visual acuity and visual field loss, often accompanied by an afferent pupillary defect, have been reported in cases of anterior ischemic optic neuropathy, central retinal or ophthalmic artery constriction, and hemicranial vasoconstriction.2
