Most of the time at least part of my visual field is continuous TV-static-like tiny flickering dots. Sometimes it expands to cover my entire visual field. This is officially called visual snow. I always thought it was part of my migraines. Perhaps it is. But it turns out that visual snow can occur independently of migraine. If you do have visual snow and migraine aura, this increases your likelihood for a whole host of fun visual weirdnesses!

Like:

  • palinopsia: the persistence or recurrence of a visual image after the stimulus has been removed
  • spontaneous photopsia: the presence of perceived flashes of light when nothing is actually happening?
  • photophobia: THE LIGHT IT BURNS
  • nyctalopia: night blindness

I get all of these except the night blindness. Luckily, most are non-existent to background noise outside of a migraine, though the visual snow gets annoying fast when I try to meditate. If I focus on it the wrong way, it gives me a migraine :/

Any visual snow, etc with your migraine?
