I sometimes get silver ball shapes falling continously in both of my eyes. They just fall straight down and about 10 to 20 flashes of this in each setting. I almost had to pull over one night driving home because it distracted my eyesite so badly. I use to take topamax and it would happen quite often. But I have been off of that for some time and it still happens. My doctor thought that is what was causing this. Should I see a eye doctor or a head doctor?
