My presenting symptom was nystagmus. I have never had optic neuritis. However, my nystagmus was severe and anyone walking down the street that looked at me could see it. There was about a week I say I was "blind" from the diplopia and nystagmus. I did see 20/20 but I also say 20 of everything.
Hope this helps, good luck to you
