Abstract

Visual snow syndrome is characterized by the continuous presence of a visual disturbance, described as dynamic dots throughout the visual field, combined with at least two other symptoms, including palinopsia, enhanced entoptic phenomena, photophobia and nyctalopia. Migraine and tinnitus are the most prevalent comorbidities. We report the case of a 51-year-old patient with a recent onset of visual snow syndrome with enhanced entoptic phenomena, photophobia and nyctalopia. The patient had a history of migraine without aura, tinnitus and sporadic episodes of vertigo, and developed visual snow following episodes of visual aura. He also reported photopsia triggered by head movements. Lamotrigine therapy partially improved symptoms. Considering the extant literature, this case is discussed to draw attention to this recently described syndrome that is often misinterpreted as a non-organic disorder.
