Does Parkinson's disease affect eyesight?

Haven't yet discussed it with neurologist, but plan to at the next
visit - I suspect, however, that it may be related to the muscle
weakness ofter associated to Parkinsons

@windyh, and for everyone in this discussion who is interested in learning more about how Parkinson's might affect your vision, here is a link to an article from the Davis Phinney Foundation website on this topic. After reading this article, you will see that vision can be impacted by Parkinson's. The vision may be affected in various ways, such as blurry vision, dry eyes, convergence (which might include double vision), etc.

@jatonlouise 👍🤣 to be honest I never expected AI to be “smart” more of an accumulation of what we feed it. I wish I had taken screenshots of all the hilariously wrong responses I’ve had in the past. It is getting better though, as I recently repeated a couple of questions it had failed on before and was hoping to capture-alas my entertainment was thwarted. I use it as a guide, then verify at credentialed sites.
Thank you so much for all the information you shared. I too am having sight issues particularly in one eye, that are puzzling my ophthalmologist.

I have had dry eyes and double vision long before I was finally diagnosed with Parkinsonism. Surgery only corrects the double vision for a short time. I had cataract surgery a few years ago, so my lenses are mostly prisms for the double vision. I have to have them changed out long before a year is up. I use drops for my dry eyes and ointment before bed. The article was very helpful.

@hopeful33250 : Thanks so much for the Davis Phinney link! The information was absolutely spot on!!!

@bruizersmom
I look forward to hearing from you again. Will you continue to post updates?

My husband 's eyes have become very light sensitive too and also dry. This coincides with his PD diagnosis three years ago. We keep sunglasses beside his chair and we need to close all the light blocking blinds in the living room on sunny days.

@jojok
Keeping the blocking blinds pulled on sunny days and keeping sunglasses handy are great ways to manage light sensitivity. You've provided some great suggestions! I appreciate your post.

So this might be the reason my eyesight has been deteriorating lately!

Thanks to Teresa for uploading this article; it was very helpful and helped me understand the reasons behind my increasingly blurry vision over the past few years.

Recently, even with a prescription, I couldn't get a suitable pair of glasses when I went to get new ones. The difference in vision between my two eyes was too great, and conventiona

l solutions wouldn't work.

Strangely enough, one time I casually picked up an elderly person's glasses and put them on, and suddenly the world became incredibly clear.

I was puzzled as to why my expensive glasses weren't comfortable, while these seemingly random reading glasses from a market worked perfectly. ...I later found the answer in this article: Reading glasses are more suitable than bifocals or progressive lenses because they provide a wider field of vision.

Sometimes when reading, the same line of text appears as two overlapping lines, making it impossible to see anything clearly?

Sometimes, the eyes can't judge distances. If you're feeling unwell that day (like not having slept enough), and you forget to slow down when going up or down stairs, you might easily misstep or miss a step and tumble down. You can't drive if you can't judge distances.

Among Parkinson's patients, those experiencing vision problems are relatively few (this is my personal guess), so it's rarely discussed. Unfortunately, I've encountered this myself. Now, without glasses, I can't use my phone, computer, or read books; I can't even tell if the spots on my face have faded!

Fortunately, I see an ophthalmologist regularly every year and follow the doctor's instructions for maintenance, so thankfully, my condition hasn't worsened!
