For some reason my Neurologists for MS are usually Neurological Ophthalmologists although I usually have no eye problems.. Wish you had one of these doctors. My first doctor was looking at use of Ophthalmologist machine that scans back of eye (where rods and cones are) to measure changes that indicates progression of MS. My present guy had done one done and found out I had Maculear Edema. Went to an Ophthalmologist. Problem resolved. Had they not been looking closely for MS progression might never had been found at such an early stage. Don't mess around with eye stuff. Most of my Neurological Ophthalmologists have been easy on the eyes too . I am in Johns Hopkins/Baltimore area (and University of Maryland Medical) and this service exists. From NY Metro area, again this exist in large quantities. May not be so easy to find in your area. (Maryland good for crabs, NJ/NY better for bagels, like that kind of)
