Hi, Cat, how long has it been since you saw the ophthalmologist? If it has been awhile, I'd suggest that the next time your vision is troubling you enough to interfere with a normal day, go see him again for a second look. If something in your vision is askew, whatever it may be, this is your only set of eyes!
Personally, I never, ever walk into my doctors' offices and tell them anything but answers to their questions. When it's my turn to ask questions, I ask about different things but am careful not to appear as if I know something they don't.

Welcome to NeuroTalk!
I hope you'll find some answers soon.
