Course: Visual Evoked Potentials in Acute Retinal Migraine

CME Credits: 1.00

Released: 2023-06-26

A 32-year-old woman presented with monocular blurred vision and photopsia of the right eye that had started 4 hours prior. Her medical history was unremarkable except for frequent episodes of most likely tension-type headache. Her sister had a history of migraine.
Visual acuity of the affected eye was reduced, its visual field (tested by finger perimetry) was normal, and the pupils were equally rounded with a normal reaction to light. Pattern shift visual evoked potentials (VEP), registered while the patient was still symptomatic, demonstrated considerably prolonged P100 and N145 latencies on the right side ().
