Visual snow is a symptom described as the continuous perception of tiny flickering dots in the entire field of vision, similar to static of an analog television. Visual snow syndrome is a cluster of symptoms found highly prevalent in patients that present with visual snow. While most of these symptoms appear to be visual in nature, approximately 63% of patients studied also report continuous bilateral tinnitus. The high correlation of visual-snow-syndrome patients presenting with tinnitus suggests that they may share a common underlying pathophysiology.
