A survey of the clinical and phenotypical characteristics of visual snow

Takeaway

  • Individuals with visual snow (VS) presented clinical characteristics that did not differ from literature reports which support the validity of the current criteria of diagnosis.

Why this matters

    VS is a neurological condition where the individual’s entire visual field is disturbed by continuous, uncountable tiny dots. Visual snow syndrome (VSS) is described as VS with visual symptoms, such as palinopsia, entoptic phenomena, photophobia and nyctalopia. The results of this study help bring greater understanding on the impacts of VS and its comorbidities in a larger cohort of individuals.
