Visual Snow Syndrome (VSS): An Evolving Neuro-Optometric Clinical Perspective

Visual snow syndrome (VSS) is a relatively new diagnosis in optometry and in medicine. VSS represents a constellation of visual and non-visual problems, with the hallmark symptom being the perception of visual snow (VS) appearing in a single plane in front of and throughout the visual field. Individuals with VS describe seeing “snow”, dots, pixelated fuzz, bubbles, and “static” as found on a poorly-tuned television. In this paper, the evolving area of VSS is briefly reviewed, a VSS symptom survey is proposed, several cases and related information are presented, and current neuro-optometric therapeutic interventions are discussed.
