Visual snow syndrome (VSS) is a rare clinical syndrome that manifests clinically with persistent positive visual phenomena, simultaneously in both eyes – multiple flickering small dots and specks, with a permanent character and involvement of the entire visual field. VSS is predominantly observed at a young age, with the onset of complaints most often in the third decade, and the female gender is more commonly affected. The pathophysiology of the syndrome has not been elucidated. Clinically, neurological and ophthalmological status are within normal limits. Magnetic resonance imaging of the brain (normal imaging finding for the age), electroencephalography (EEG) and cerebrospinal fluid examination were performed diagnostically, which did not show any pathological deviations. The differential diagnosis of the syndrome includes neurological, eye and some other diseases, use of hallucinogenic substances and medications. Therapeutically, Lamotrigine and Acetazolamide are recommended as the first line of treatment, followed by Topiramate, Lorazepam, Clonazepam and.
