Understanding visual perception in visual snow syndrome: a battery of psychophysical tests plus the 30-day clinical diary

Brain Communications
Patients with visual snow syndrome (VSS) experience uncountable flickering tiny dots in the entire visual field. Symptoms often persist over the years. Very little is known about altered perception in VSS.

Elucidating the Visual Snow Spectrum: A Latent Class Analysis Study

Behavioural Neurology
Objective. People with visual snow syndrome (VSS) experience a range of perceptual phenomena, in addition to visual snow (VS; flickering pinpricks of light throughout the visual field). We investigated the patterns of perceptual phenomena associated with

A Case of Unilateral Presentation of Visual Snow Syndrome

, 2022
Visual snow syndrome is an uncommon disease that is characterized by persistent positive phenomena that look like pixelated static similar to static on a television screen. Diagnostic criteria proposed by Schankin et al.
