Visual snow syndrome: Applications & Research

Visual snow syndrome (VSS) (coined by Liu et al in 1995) is a neurological condition in which the primary symptom is persistent flickering white, black, transparent, or colored dots across the entire visual field. It is distinct from the symptom of visual snow itself, which may be caused by multiple ophthalmic and vascular conditions.
