Bob, When I read about Nancy's double vision, I had to let you know that according to the speaker we had at April's PFHC meeting, PD CAN be the cause of double vision. She (Dr. Kathryn Brady-Mc Creery from Baylor's Ophthalmology dept.) said most people don't think it's from PD but it is and she was able to correct the problem using prisms in glasses or possibly implanting them. You can check with me if you want to talk to someone who successfully used her after having needless surgery to try to correct the problem. nina ROBERT A MARTONE wrote: > Reply to Bob Fink > > Bob, > > Nancy is now 5 years post PVP and continues to benefit from > the absence of dyskinesia. > > She is 55 years old and has had PD 25 years. > > Almost no circumstance or medication has been observed that > rekindles the dyskinesia that was so disabling to her. > (Unable to feed herself.)
