Parkinson’s disease symptoms: Three warning signs found in a person’s eyes

People with Parkinson’s disease often experience problems with their eyes and eyesight as a result. What are three warning signs of the disease found in a person’s eyes?

Parkinson’s disease is a progressive nervous system disorder which sadly cannot be cured.

Having said that, the earlier one picks up warning signs, the better it is for management and medication.

Symptoms of Parkinson’s are mainly related to movement, but other areas of the body are also affected.

The eyes could show many different and unusual signs warning that something is not quite right, according to Parkinson’s UK. 

Dry eyes

Parkinson’s disease sufferers may blink less often than other people, the charity advised.

Blinking is a way to help remove dust and dirt, so when a person blinks less, these particles can build up.

This in turn makes the eyes become more dry and painful.

Dry and sore eyes do have many other health reasons so it’s best to discuss with an optometrist if suffering with this condition.

Eyelid apraxia

Eyelid apraxia occurs when the muscles that open the eyelids have trouble opening, explained the charity.

It continued: “This often happens during speech and sometimes the eyelids might close completely and stop you being able to see properly

“In mild cases of eyelid apraxia, simply rubbing the eyelids might help.

“Sometimes, injections of botulinum toxin (botox) are used to treat eyelid apraxia.

“Speak to your specialist for advice.”

Double vision

Double vision is when you see two images of a single object at once.

Parkinson’s UK said: “This can happen for varying amounts of time.

“The two images you see may be on top of each other, side by side, or a mix of both.

“Some people with Parkinson’s experience ‘tracking’ and this is when the eyes have problems moving smoothly across a line or from one object to another.

“If the problem continues, see your optometrist for advice, or ask your GP or specialist if you can be referred to an ophthalmologist for further tests.

“Slight changes in your glasses prescription might also help with double vision.”

Visual disturbances can be part of Parkinson’s disease.

The reason for this is because the condition causes a loss of retinal cells in the eye which rely on dopamine to process and perceive colour.

Parkinson’s disease may also impact a person’s eyelids.

Dryness, burning and irritation are common problems for Parkinson’s sufferers, and this is due to a lack of blinking.
