Hi LA, sorry you're dealing with this. Loobie's right about the site he gave, but the link didn't work for me. It's a great suggestion, though. Here's one to the page on eye issues in general: http://www.mult-sclerosis.org/mssymptoms.html
And here's a link to the page there about nystagmus, which is jerky eye movements:
Nystagmus is rapid, involuntary movements of the eyes which is often unnoticeable to people with the complaint. To others it resembles the eye movements when someone is looking at the scenery from the window of a moving train. Usually it occurs in the horizontal plane but it can also affect the vertical.
That's one of the few named symptoms my neuro could actually notice in one of my exams (I've never even been dx'd with ON), although I've whined to her about dozens.
It must be so minor in my case it doesn't seem to bother me.
Hope you find a lot of answers at that site.
