So much doubt exists as to our aches, pains, strains, unusual symptoms in a day in the life of a PWP, that we often ask : Is this due to my Parkinson's per se? or Is it a reaction to one of my medications? or Did I simply overstrain a muscle? Symptoms concerning vision and eye movement are particularly difficult to fathom. Would our Ophthalmologist, Dr.Jacquie Winterkorn, please shed a little light on how Parkinson's and the medications affect vision. Thank you, Doctor. [log in to unmask] (Mary Manfredi)
