Hi bamy,
First off from what I recall, if you are on Parkinson's medications, you usually will have some relief from the medications. I don't recall that Parkinson's patients had visual problems, but then again, I could be wrong. Has anyone ever discussed something called "DEVIC's Disease" with you? I do believe that some of the symptoms of both MS and Parkinson's overlap in Devic's.

You may want to contact Cherie who is an MS Certified Nurse. She may be able to help you with this type of question. May you find the answers you are looking for.

All the best to you,

Chris
