My system shows that you are online but you don't seem to be reviewing my posts; perhaps you have stepped away from your computer. I also see that you have used justanswer before so you understand how the system works....
Let me answer your question as I understand it:
Parkinson's disease can cause a large number of body wide problems including issues with the eyes. First of all the disease, as well as many of the medicines used to treat Parkinson's can cause dry eyes
. Your history of turned in eyelashes would tend to make this issue worse. These problems can cause double vision due to tear film
abnormalities and problems with corneal exposure. The best way to treat this is with a stepwise approach:
First, the use of natural tears 4-6+ times/day to augment your natural tear production, if this doesn’t work then you can try temporary punctal occlusion of the lower puncta, then, if needed, temporary occlusion of all 4 puncta then, if indicated, surgical ( non-reversible) closure of the puncta. The openings to your tear drainage system are called puncta and you have one opening on each lid, near your nose.
If this doesn't help with your double vision your problem may be rooted in your parkinson's disease itself causing problems with your eyes working together. This is particularly common with near vision tasks and when looking up. The best person to evaluate you for this issue would be a neuro-ophthalmologist
. Perhaps your GP would be willing to refer you.
I very much doubt that glasses or your eyelids are the root cause of your problems, as much as your optician and GP would like it to be. I suggest you have a complete eye exam by an ophthalmologist as well as review your symptoms with the doctor treating your parkinson's disease. Perhaps he can change around some of your meds.
Does this make sense to you?
