I am also from the MS forum. PastorDan and I have what sounds like the same thing going on. Several bout of eye pain when I move eye. Started Jan 08 in L eye Opto said no ON, mildly abnormal visual field test, VEP done several months later and it was Neg. During that year, 2 more times with eye pain not as bad got checked once no ON. And just recently R eye pain had to see different Opto, mine was on vacation, this one felt ON, only because I am suspescious(spelling) for MS. Visual field test normal. Based on what I have read I am not sure that this was ON. I have not had another VEP since the first one. But if not ON what could it be? Oh BTW no real blurred vision or color disturbance with any of this. Any comments would be great.
