Abstract

Background: Retinal migraine is defined by fully reversible monocular visual phenomena. We present two cases that were complicated by permanent monocular vision deficits. Cases: A 57-year-old man with history of retinal migraine experienced persistent monocular vision loss after one stereotypical retinal migraine, progressing to finger-count vision over 4 days. He developed paracentral acute middle maculopathy that progressed to central retinal artery occlusion. A 27-year-old man with history of retinal migraine presented with persistent right eye superotemporal scotoma after a retinal migraine. Relative afferent pupillary defect and superotemporal visual field defect were noted, consistent with ischemic optic neuropathy. Conclusion: Retinal migraine can complicate with permanent monocular visual loss, suggesting potential migrainous infarction of the retina or optic nerve. A thorough cerebrovascular evaluation must be completed, which was unrevealing in our cases. Acute and preventive migraine therapy may be considered in retinal migraine patients, to mitigate rare but potentially permanent visual loss.
