Que es el visual snow?

Answer 1

"Visual snow is a transitory or persisting visual symptom where people see snow or television-like static in parts or the whole of their visual fields. According to the notion of hallucinatory form constants by Klüver (1942) and Siegel and Jarvik (1975), it can be conceived as a variety of visual hallucinations of random form dimension. As such, the phenomenon should not be confused with normal entoptic phenomena such as Haidinger's brush, which almost never have sufficient intensity to gain clinical significance as a source of suffering or functional impairment."
