My advice to anyone experiencing eye problems....try your best to get to see a NEUROopthamologist. They should be able to detect activity whether it is actually syptomatic or not.

My quick story......2 years ago I got a blind spot in the center of my vision in my left eye. This was a Friday night, it got worse, and by Sunday, I was off to the emergency room. Luckily for me the Doctor immediately brought in an opthamologist who in turn immediately directed me to see a Neuro-opthamologist. With this came an immediate diagnosis of ON and an IV treatment. And within a couple weeks, a diagnosis of RRMS. The neuro obviously found the ON in my left eye that was occuring, but he also said that he saw that I had nerve fiber damage in my right eye, meaning I had an attack but obviously it was not bad enough to produce symptoms.

I've been a lurker here for some time, but just wanted to briefly share my experience and encourage everyone to see a neuro-opth...if at all possible.
