A 14-year-old girl with a history of migraine headaches and methylphenidate use presented with 2 episodes of prolonged but completely reversible inferior altitudinal homonymous visual field loss, lasting 5 days and 4.5 weeks, respectively. Neuroimaging studies were unremarkable. We discuss the potential causes of our patient's visual symptoms and speculate and hypothesize that it may represent an atypical manifestation of migraine, perhaps related to a channelopathy.
