lately my vision got problem when off., either out focus or double vision . Is this one of the symptoms?

[Boscoejean]

this is a possibility

"People with Parkinson's disease often experience vision problems like double vision, blurry vision, dry eyes, difficulty moving the eyes smoothly, problems with color perception, and sometimes visual hallucinations, all stemming from impaired eye muscle control due to the disease's impact on the nervous system; these issues can make tasks like reading or navigating challenging.

Key vision problems associated with Parkinson's:

Double vision (diplopia): Caused by difficulty coordinating eye movements, leading to seeing two images of the same object.

Blurred vision: Can occur due to issues with eye movement control or decreased blinking leading to dry eyes.

Dry eyes: Reduced blinking frequency is common in Parkinson's, causing discomfort and blurry vision.

Difficulty with eye movement: Problems initiating eye movements or tracking moving objects smoothly.

Convergence insufficiency: Difficulty focusing on close objects, leading to double vision when reading.

Color vision impairment: Difficulty distinguishing between certain colors.

Visual hallucinations: Seeing images or people that aren't there, which can be a symptom of advanced Parkinson's.

Why does Parkinson's affect vision?

Dopamine depletion:

The brain chemical dopamine plays a vital role in eye movement control, and its loss in Parkinson's leads to impaired eye coordination.

Neurological damage:

The areas of the brain responsible for visual processing are affected by the degenerative process in Parkinson's.

What can be done about vision problems in Parkinson's?

Eye exams: Regular checkups with an ophthalmologist to monitor vision changes and address any concerns.

Prism glasses: Can help correct double vision by adjusting the way light enters the eye.

Artificial tears: Eye drops to alleviate dryness.

Medication adjustments: In some cases, adjusting Parkinson's medication may help alleviate visual symptoms.

Visual rehabilitation therapy: Exercises to improve eye movement control and visual perception. "

Let me emphasize one point in the comprehensive reply from Boscoejean. My ophthalmologist told me to put eye drops for dry eyes 4 times a day. He said this is necessary to prevent damage to the surface of the eye. So we shouldn't wait until we feel discomfort, which is what I was doing before he told me this,

Can happen 1.Ocular muscles can be "off" mode

2. Embedded involuntary muscles can be affected by autonomic dysfunction.

But don't assume that it is just PD.

Get it checked out especially IOL or intraocular pressure.

I have had nystagmus since childhood, possibly birth. It has definitely been getting much worse since my diagnosis.

Thank you ! Did you read this whole thing? I couldn't. I fall asleep when there is technical writing this long. Is there a tldr version?

[Boscoejean in reply to gomelgo]

I will try to see if I can find the abstract on that. Try this

I have eye problems, just seen a specialist last Friday and had scans done. Maybe it could also be because mitochondria can be abnormal in PD. I have abnormal mitochondria and now I am getting ptosis. Just a thought.
