Visual Snow

|
Visual snow is a little-known condition in which people see snow or television-static in their field of vision. Usually the condition worsens in low light conditions or when closing one eye. The causes of the condition are still unknown, but some patients have associated it with stress, LSD/MDMA use, weightlifting, anti-depressant usage, panic attacks and other events. However, other patients fail to find such an event in their lives, instead saying the snow came out of nowhere or has been with them for their whole life.
People with visual snow often have floaters and some have other visual disturbances as well, like starburst, increased afterimages and trails.
Because there is little scientific data on the condition, visual snow is not diagnosed as such. Instead, it is often seen as a persistent form of acephalgic migraine.
There currently is no established treatment for visual snow, although some people claim to have benefited from the anti-seizure medicine Clonazepam or from the corticosteroid Prednisone. However, with no scientific research on the condition taking place, such treatments remain based solely on anecdotal evidence.
