Hi Mike.....I too had optic neuritis back in the "dark ages" -- 1976 and again about a year later. In hindsight, it was the beginning of my MS, but didn't get the official diagnosis until 1990. When the ON was active, I had a blind spot eliminating my peripheral vision. Had a wicked pain over my eye and it was painful to move my eyeball. Eventually this all cleared up.

Now, 34 years later, my vision is quite blurry, especially when I'm tired or the MS is flaring. I have pain behind my eyes if I have to look straight up and severe dizziness if I move my eyes too quickly. Perhaps your flare is causing your eye problem too?? As others have said, find a new neurologist asap.

Take care......
