Parkinson’s symptoms: The changes to your eyesight that could be a warning sign

Parkinson’s  is a condition affecting the automatic nervous system, meaning the symptoms can present themselves in almost every one of your bodily functions – including your eyesight. Here are the unusual symptoms of Parkinson’s affecting your eyesight.

Parkinson’s has many different symptoms, and the condition can present differently for different people.

The most well-known symptom of Parkinson’s is developing a tremor. While this is one of the tell-tale signs of the condition, it is far from the only symptom.

Parkinson’s starts in your brain and is a neurodegenerative disease.

This means as time goes on, the condition affects more parts of the brain and symptoms affecting your movement can become more pronounced.

Symptoms of Parkinson’s are divided into two categories: motor and non-motor symptoms.

Motor symptoms are those affecting your movement, which is perhaps why they’re more well-known, as they’re easier for a doctor to detect.

Non-motor symptoms can affect other areas of your automatic nervous system, affecting different bodily functions from bladder control to your moods.

One lesser-known symptom of Parkinson’s is changes to your eyesight.

How can Parkinson’s affect your eye health?

One possible symptom of Parkinson’s is irritation to your eyes.

You might experience dry eyes as a result of blinking less than normal.

Double vision can also be a symptom of Parkinson’s, where you see two images of an object as if they’re on top of each other.

Blurred vision can also occur as a result of your eyes having difficulty moving.

Some people also experience colour blindness, or difficulty telling colours apart.

Some Parkinson’s medications might help to relieve some of the symptoms affecting the eyes, but you should mention any issues with your eyesight to your doctor to investigate.

What are the most common symptoms of Parkinson’s?

The three most common – also known as “cardinal” – symptoms of Parkinson’s are:

  • Developing an involuntary tremor
  • General muscle stiffness
  • Slowness of movement – this could be noticeable when walking or when changing facial expressions

However it’s important to remember the symptoms of Parkinson’s can be diverse, affecting people very differently.

Other symptoms of Parkinson’s include:

  • Constipation
  • Low blood pressure
  • Sexual problems (for example, erectile dysfunction or decreased libido)
  • Sweating more
  • Changes to your bladder and bowel habits
  • Memory problems
  • Low mood
  • Fatigue

If you are concerned about Parkinson’s, you should speak to your doctor about your symptoms and whether you should be referred to a specialist for an assessment.
