How Parkinson’s Affects Your Vision

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery now or in the future? Our Madison eye doctor has prepared the following answers to your questions about eye disease.

Patients With Parkinson Disease At Increased Risk Of Vision Eye Issues Study Shows

Patients with Parkinson disease were found to be more likely to experience vision and eye issues, such as blurry vision, dry eyes, trouble with depth perception, and problems adjusting to rapid changes in light, compared with people without the disorder, according to study findings.

Patients with Parkinson disease were found to be more likely to experience vision and eye issues, such as blurry vision, dry eyes, trouble with depth perception, and problems adjusting to rapid changes in light, compared with people without the disorder, according to study findings published in Neurology.

In patients with PD , irregular eyesight can prove a chief issue, as ophthalmologic disorders combined with postural and gait instability from the disorder may increase the risk of falls and fall-related injuries, noted the study authors.

Risk of vision impairment is potentially common for PwP because PD is linked with retinal dopamine depletion and decreased dopaminergic innervation of the visual cortex, which can lead to visual problems such as diminished oculomotor control, contrast sensitivity, color vision, and visuospatial construction. PwP are also at increased risk for seborrheic blepharitis and keratoconjunctivitis sicca .

In PwP with ophthalmologic symptoms, 68% reported that it interfered with daily activities, compared with 35% of controls .

APDAUncategorizedEye Problems in Parkinsons Disease

PD patients often have a lot of difficulty with their vision, although, when I examine them in the office, the visual acuity is often normal. Problems can come from difficulty in moving the eyes and eyelids, as well problems with blinking and dryness. Most of these conditions arise from Parkinsons Disease itself, while others may be caused by the medications required to treat PD.

Many Parkinsons Disease patients complain of trouble reading. One common cause of this is called convergence insufficiency. In order to see clearly up close, normal eyes must converge or cross inwards to see a single image. If convergence is defective, a person will have double vision when trying to see close up. Sometimes placing prisms in the reading glasses can alleviate this problem. Often, however, just covering one eye may be the only way to eliminate the symptom.

Other eyelid movement problems can contribute to visual difficulty in Parkinsons Disease patients. Parkinsons Disease patients may have intermittent blepharospasm, especially when the eyelids or brows are touched. The patient involuntarily squeezes his eyes shut and may have difficulty opening them as well. This is why Parkinsons Disease patients often have difficulty during eye exams, when the doctor is holding the eyelids open for examination or to measure eye pressures.

My Parkinson’s Story: Visual Disturbances

This 6-minute video alternates between an interview with a man and and doctors. The man shares his vision changes due to Parkinson’s disease. The doctors explain that the muscles of the eyes develop a tremor in those with Parkinson’s disease, causing blurry vision. Parkinson’s medication reduces eye tremors by 75-90%, but eye exercises and reading are also beneficial.

Vision Problems Are Common In Parkinsons

Parkinsons disease: Feeling this sensation in your eyes ...

Research has shown that visual symptoms are extraordinarily common in people living with Parkinsons. Visual symptoms may occur due to changes in the front of the eye due to dry eye, changes in the retina , or changes in how our eyes move together. At the same time, many other things can affect vision, including diseases such as age-related macular degeneration, glaucoma, and cataracts, which increase with age. Distinguishing between visual symptoms caused directly by Parkinsons versus one of these other conditions can be difficult.

Visual symptoms related to Parkinsons can be specific: eyes can feel dry, gritty/sandy, and may burn or have redness. You may experience crusting on the lashes, lids that stick together in the morning, sensitivity to light, or dry eye. On the other hand, symptoms can be non- specific: you may notice your vision just isnt what it used to be, and you have difficulty seeing on a rainy night, in dim lighting, or while reading, etc.

Potential Effects Of Parkinsons Disease On Eyesight

By Patricia Schumacher 9 am on March 27, 2020

Growing older often means a greater risk of experiencing certain vision problems, such as cataracts and age-related retina damage . Typically, these changes have nothing to do with Parkinsons disease and can affect any older adult. However, there are some vision issues specifically related to this condition. Five of the more common ones are discussed below.

Difficulty Moving The Eyes

You may have difficulties when starting to move your eyes or when trying to move them quickly. This might be more noticeable when looking at fast-moving objects, such as cars. Sometimes, instead of a smooth movement, your eyes move in a slow and jerky way. Difficulties in moving the eyes up or down are more common in progressive supranuclear palsy than Parkinson’s.

Everyone Needs Regular Eye Exams

Even people with perfect eyesight should schedule regular eye exams as part of their preventative care routine. These exams are essential for screening for eye diseases and preserving your vision. Typically, an eye exam includes visual acuity tests , depth perception tests, eye alignment, and eye movement. Your eye physician may also use eye drops to dilate your pupils, allowing them to check for common eye problems such as diabetic retinopathy, glaucoma, and age-related macular degeneration.

These are important for people with Parkinsons to keep in mind for two reasons: first, up to half of all vision loss in the US is preventable or treatable with early detection through annual eye exams, and second, vision loss has a disproportionate impact on people with Parkinsons: it increases the risk of falls, hip fractures, depression, anxiety, hallucinations, and dementia.

The American Academy of Ophthalmology recommends that all adults over 65 receive a comprehensive eye exam every one to two years. The recommended frequency of eye exams is every two to four years for age 40-54 and every one to three years for age 55-64. If you have a history of diabetes or are at an increased risk of glaucoma , you should have an eye exam every year regardless of age.

Moving Through Eye Challenges

Reading about disorders like this isn’t easy, especially when many of them cause permanent damage. It’s important to understand that you don’t have to take on these challenges alone.

Opticians, ophthalmologists, and other eye experts are adept at both examining eyes and developing treatments for deficits. A visit to an expert like this could result in solutions you would never have thought of on your own.

And a relationship with an eye doctor could help you to prevent some of these issues from ever developing, so you can preserve your vision throughout your life.

If you don’t have an expert on your side now, it’s time to start searching.

Screening Tests And Recommended Treatments

We recommend starting the examination by excluding severe visual impairment. This can be done by briefly testing the near visual acuity . This is an excellent screening test since it is easy to administer and because only few significant disorders leave visual acuity unaffected. Above the age of 45, appropriate reading glasses are required for normal near vision. Reading acuity as well as reading speed are good predictors of everyday visual function . Moderate vision impairment can be defined as < 6/24 on the visual acuity test and severe vision impairment as < 6/60 . Dopaminergic medication may influence visual acuity, causing refraction changes during the medication cycle. Therefore, some patients may need adapted glasses depending upon the medication phase. Referral to an ophthalmologist is advised in case of significant vision impairment.

Changes In Sleeping Patterns

As Parkinsons progresses, you can also develop problems with sleep patterns. These may not happen in the early stages, but can be noticeable later. You might wake up often in the middle of the night or sleep more during the day than you do at night.

Another common sleep disturbance for people with Parkinsons is rapid eye movement sleep behavior disorder. This is when you start acting out your dreams in your sleep, such as verbally and physically, which can get uncomfortable if someone is sharing your bed. Dr. Rundle-Gonzalez says many times a bed partner will be the one to notice sleep problems.

REM sleep behavior disorder can also happen in people who dont have Parkinsons. However, if this isnt something youve dealt with before, its likely related to your disease. There are medications your doctor can prescribe to help you sleep comfortably through the night.

Optic Neuritis: An Inflamed Optic Nerve

Your optic nerve works like a sight highway. Signals move from the eye to the brain down this path, and it’s that movement that helps you to see clearly. Swelling in the optic nerve can slow or even block those messages.

Optic neuritis is closely related to multiple sclerosis . This condition causes nerves all around the body to swell, and researchers say about a third of people with MS don’t know they have the condition until they develop optic neuritis.

It’s also been associated with risks such as:

  • Infections. Lyme disease, syphilis, cat-scratch fever, and bacterial invasions can all cause the optic nerve to swell.
  • Viruses. Herpes, mumps, and measles can cause optic neuritis.
  • Medications. Some types of antibiotics and the drug quinine can cause swelling in the optic nerve.

Optic neuritis usually attacks one eye while leaving the other intact, says Mayo Clinic. You might notice:

  • Vision loss. Some people develop a slight blurring or dimming of vision, while other people can’t see anything at all. Some people retain clear central vision, but can’t see anything to the side.
  • Visual hallucinations. You may see flashing or flickering lights. Colors might seem dim or dull.
  • Eye pain. You might develop a headache, and it can get worse when you move your eyes.

MS is a degenerative disease that requires medical management. The earlier you get help for that issue, the better.

A Slow Blink Rate May Help Replenish Dopamine

People develop Parkinson’s disease when they lose dopamine or dopaminergic neurons in the substantia nigra area of the brain. The dopamine system plays an essential role in muscle function and motor physiologyhence its reputation as a movement disorder.

Surprisingly, some experts believe that reduced blink rates are more than just the result of muscle slowness or stiffness resulting from a lack of dopamine. They may in fact be the body’s way of trying to increase one’s light exposure, which in turn helps the body develop more dopamine.

One study published in the International Journal of Neuroscience explains that blinking helps to regulate light-dark exposure, which helps “fine tune” melatonin and dopamine production. “Decreased blinking could reflect a compensatory mechanism to increase light exposure, reduce melatonin production and ultimately increase dopamine functions,” the study concludes.

Parkinsons Disease: Motor Control And Nerve Damage Combine

Ask the Expert: Can COVID-19 Affect Your Eyes?

When we think of Parkinson’s disease, we think of muscles. People with the condition tend to slur their words, stumble as they walk, and jerk their arms and legs periodically.

Damage to myelin, or the nerve’s protective covering, is to blame. That allows nerves to drop or cross signals. But the condition can also interfere with vision, even if the eye itself has no muscles within it.

People with Parkinson’s disease can experience problems with:

  • Focus. When you can’t control the muscles around your eye, it’s hard to look closely at an object. Your eyes may not look in the same direction, or they may not stay in one place for long enough.
  • Color perception. The disease can kill off retina cells at the back of the eye, researchers say, and when that happens, it’s harder for you to perceive colors. Everything may appear gray, or the world may seem washed out.
  • Dry eye. When muscles don’t fire properly, blinking is tough. Some people with Parkinson’s disease don’t blink frequently enough, and their eyes feel dry and gritty.

Parkinson’s disease can develop due to family history, but Parkinson’s News Today suggests that risk can rise due to:

There is no cure for Parkinson’s disease, says the American Parkinson Disease Association. But some treatments can ease your symptoms. Your doctor might use:

Your doctor may choose eye drops to keep the eyes moist. And special glasses may help you focus your attention, so you can read and handle other tasks without disruption.

Difficulty Reading & Other Pd

The quick eye movements that allow the eyes to shift to a new vision target can slow down as Parkinsons disease progresses. Should this happen, it can be difficult for seniors with PD to follow words on a page as they go from one line to the next while reading. Older adults with Parkinsons may also experience other vision problems involving: The ability to follow moving targets in a side-to-side direction Blinking to change eye positionLevodopa, the most common PD drug, may help The ability to see a target coming right at the eyes Difficulty voluntarily opening/closing eyes possible solutions include doing eyelid crunches or having Botox injections

There are a variety of age-related health conditions that can make it more challenging for seniors to live independently. However, many of the challenges they face can be easier to manage if their families opt for professional home care services.

Managing Eye Movement Problems With Pd

If you are experiencing visual changes, it may be time for a lens prescription adjustment, which is normal as we age. See an ophthalmologist or optometrist to rule this out. If they cannot solve the problem, ask for a referral to a neuro-ophthalmologist and/or movement disorder specialist.

Neuro-ophthalmologists bridge the gap between ophthalmology and neurology by diagnosing and treating the vision issues with neurological diseases.

If an eye movement abnormality is found, you may be prescribed two pairs of glasses, one for distance and the other for close activities and reading. This often works better than bifocals. If you are found to have convergence insufficiency, you may be prescribed glasses with prisms. Prisms help to bend light to the proper focal point on the retina when the eyes are not able to achieve this on their own.

Dyskinesia can also affect the eyes and cause blurred vision. If someone is experiencing dyskinesia in other parts of the body, this might be the reason for visual disturbances. Dyskinesia typically happens in the on state when Parkinsons symptoms are otherwise well-controlled, some people experience worsening of vision as medication starts to wear off and Parkinsons symptoms return. Medication adjustments may be the solution.

Next weeks blog post will feature more information on other eye disorders due to PD, and the related treatments.

There Is A Wide Array Of Vision Problems People With Parkinsons May Experience

Here are several common, and a few not-so-common, visual symptoms you may experience:

Blurry vision and difficulty with color vision. Blurry vision may be related to dopamine depletion in the back of the eye and within the visual connections through the brain. This may be partially corrected with dopaminergic medications, though medication effects are usually subtle regarding vision, so you may not notice them.

Visual processing difficulty. This refers to the orientation of lines and edges, as well as depth perception. This can take different forms, including:

  • Troubles with peripheral vision: distracted by objects and targets in your peripheral vision
  • Difficulties perceiving overlapping objects
  • Difficulty copying and recalling figures
  • Difficulties detecting whether motion is occurring and in which direction
  • Difficulties recognizing faces, facial expressions, and emotions

Dry Eye. Dry eyes are a consequence of decreased blinking and poor production of tears. Dry eye can be worsened by certain medications prescribed for Parkinsons. Dry eye improves with liberal use of artificial tears and good eye/eyelid hygiene. Of note, dry eye doesnt always feel dry! Sometimes it feels like watering, and other times it just feels like blurring or being out of focus.
