Get her a new neurologist, and probably find her a neuro-ophthalmologist for treating any vision related flares. Like it was said before, oral pred is NOT the treatment for optic neuritis.

I have a neuro for general MS stuff. An ophthalmologist for vision stuff, a physiatrist for when I have flares that cause me problems with getting around, and then my regular doctor for the more normal every day things that have nothing to do with the MS.

Why did they do the MRI without contrast?
