Parkinson’s disease: Eye symptoms include dry, colour vision, double and fluttering

0

Parkinson’s disease is the second most common neurodegenerative disease, affecting over 10 million people worldwide. Your eyes and vision may hold clues pertaining to your risk to the condition.

Double vision

Double vision is when a person sees two images of a single object either some or all of the time.

The two images may appear on top of one another or side by side – sometimes a mixture of both.

The charity says: “This is often caused by problems moving the eyes.”

It adds that some people with Parkinson’s experience ‘tracking’.

“This is when the eyes do not move smoothly across a line or from one object to another,” it explains, “for example moving across a page when reading, or up and down”.

A refractive error can be picked up by an ophthalmologist or optometrist.

In order to diagnose an eye movement problem however, different types of evaluations need to be done that may not be performed at a routine visit with an ophthalmologist.

Therefore, if you are having visual problems and a trip to the ophthalmologist with a new lens prescription does not solve the problem, ask for a referral to a neuro-ophthalmologist.
