| Glowing disks
When I'm in a dark room and I move my eyes left or right, I see a large glowing disk. It's in both eyes, meaning that I can shut either eye and still see the disk in the other eye.
Does anyone have any idea what this might be? It's been going on for about a year (I've also had some undiagnosed neurological problems - something similiar to MS, but all MS testing has been normal.)
