RESUMEN
We present a case report of a 17-year-old obese female with one-week onset of progressive confusion and double vision, associated with 50-pound weight loss in five months. On fundus examination, retinal hemorrhages and abnormalities of eye movements were seen. MRI showed abnormalities that were consistent with diagnosis of Wernicke encephalopathy (WE). Thiamine replacement caused gradual improvement in patient's symptoms. Peripapillary hemorrhages on fundus examination, as seen in our patient, have been rarely seen in WE. Obesity with retinal hemorrhages, diplopia, etc. can be misleading due to idiopathic intracranial hypertension being the most common presentation in this subset. Thus, fundoscopy should be part of routine examination in WE-suspected patients.
