I know of a woman in Wyoming who had the injections because she had virtually lost her vision. She had them at Mayo's in Scottsdale, Ariz. It sounds terrible, but I know it is well recognized -- injections of botulism. It doesn't permanently cure the problem, but I understand that it lasts 2 or 3 years. I believe that the specialists in PD feel that there is a similarity between the maladies. [log in to unmask] (Laramie, Wy)
