The prevalence of visual snow syndrome in the UK is
1.4%–3.3%. Visual snow syndrome is associated with
tinnitus and, possibly, to a lesser degree with mood
impairment and headache. It is of note that unprimed
laypeople with visual snow syndrome in the general
population are on average older than those seeking
medical attention and, perhaps, less concerned.
Although prospective follow-up data are needed,
visual snow syndrome is very unlikely to be a progres-
sive disorder. We suggest that reassuring information
can be given to those seeking medical attention for
visual snow syndrome.
