Visual Snow

Visual snow is a neurological disorder that affects the way the brain processes images and causes abnormal vision changes. It is important to note, no structural abnormalities exist within the eyes. Images may constantly appear with floaters, flashing lights and/or static and these symptoms remain with closed eyes. Other symptoms that may co-occur are photophobia, tinnitus, palinopsia, nyctalopia and more.

“Of 120 patients with “visual snow,” 70 patients also had migraine and 37 had typical migraine aura.”¹
