Anya - Yesterday, the nystagmus came back again. I've only gotten a 2 day reprieve from it. UGH! So this morning I googled nystagmus in MS and found this article. I thought of you and decided to share this link. I can certainly share some of your frustration. For me though, it is only eye pain and a jittery eye that affects my vision but it has been going on since the end of December. Based on this article, it appears that what I am experiencing is saccadic intrusions which, from what I gather from the article, these are not caused by the optic nerve but a lesion in the brainstem or cerebellum, which I do have. I thought it interesting because we always associate eye trouble in MS as being an optic nerve issue but, based on this article, that doesn't seem to always be the case.
