Case Report: Visual Snow Syndrome after Repetitive Mild Traumatic Brain Injury

CONCLUSIONS Although rare, visual snow syndrome should be considered in all patients reporting continuous pixelations in their vision for more than 3 months, especially when accompanied by at least two of the following: photosensitivity, palinopsia, enhanced entopic phenomena, or nyctalopia. The pathophysiology is still unclear at this point, with evidence suggesting a link to the secondary visual cortex, specifically the lingual gyrus. More studies are needed to determine the exact cause, especially studies that separate visual snow syndrome patients with and without comorbid migraine. Because the pathophysiology is unclear, the treatment course is also unclear. Anecdotal evidence may suggest that tinted lenses may be of some value.
