Abstract:
A systematic review of visual snow syndrome(VSS)was introduced in this article. Scientists don't know what caused visual snow syndrome for sure, but studies have shown that patients with VSS experience continuous television-static-like tiny flickering dots in the entire visual field and additional visual symptoms such as palinopsia, entoptic phenomena or photophobia or nyctalopia. Literature in recent years on the clinical and pathophysiological researches of VSS was reported, and in the latest literature, the VSS was more inclined to be seen as a visual processing disorder. It should be distinguished from the migraine and other diseases. In terms of treatment, current studies focused on experimental studies. Some case reports showed that anti-Seizure medications, antidepressants, or acetazolamide and colored filter-sheet may be effective in eliminating symptoms.
