Central retinal vein occlusion in a migraine patient

摘要

We describe a 31-year-old woman with a history of migraines without aura, who presented to our emergency department due to a monocular visual disturbance. This was misdiagnosed as being related to her migraine, however, it was subsequently found to be caused by a central retinal vein occlusion. Patients suffering from migraine can experience visual disturbances in the form of auras. The neuropathological basis for this phenomenon is thought to be a spreading depression in the visual cortex, causing a hemifield active visual phenomenon. Missing the diagnosis of central retinal vein occlusion is common, especially in the setting of an initially normal fundoscopy examination. (C) 2015 Elsevier Ltd. All rights reserved.
