My mother, who is 82 and formally diagnosed 7 years ago, is progressing rapidily. Of major concern to her is her inability to read. I accompanied her to the eye doctor several years ago and heard him theorize that her eyes were no longer focusing together because of Parkinson's affecting her eye muscles. Another eye doctor said not enough light was entering because of her cateracts, but he did not recommend removing them, they weren't severe enough. (??) Another doctor said that dry eyes might be the problem and recommended using eye drops to wet the eye surface. She is now unable to lift here eyelids far enough to allow clear vision from the pupil. Her sister also has drooping eyelids. So maybe the lid problem is not from PD? but from heredity? Does anyone else have vision problems?
