How Often Should I Get An Eye Test
If you have Parkinsons, its recommended that you have an eye test with an optometrist at least once a year. You should try to do this even if you arent experiencing any problems with your eyes.;
You must tell the DVLA if you have any problem with your eyesight that affects both your eyes, or the remaining eye if you only have one eye.;

The Opposite Can Also Happen In Pd Patients
While less common, some Parkinson’s patients experience the opposite symptom: excessive blinking, known as blepharospasm.
Those who suffer from blepharospasm may benefit from seeing an ophthalmologist or neuro-ophthalmologist, who can inject a botulinum toxin in the muscle surrounding the eye every three to four months. This treatment, performed by a movement disorders specialist, is known to be very effective in slowing blink rates and improving eye function.
How Parkinsons Disease Can Affect Vision
By Shital Rane 9 am on March 13, 2020
The main characteristic of Parkinsons disease is difficulty with movement that becomes increasingly noticeable as the condition progresses. However, there are many non-motor complications associated with this disease as well, one of which is vision impairment. Eye changes associated with age, such as the development of cataracts, can also affect seniors with PD, but were going to focus on vision issues specifically linked to Parkinsons disease.

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.
Types Of Eye Movements
There are three kinds of eye movements that can change with PD:
- Saccadic rapid eye movements direct us to gaze at a specific object or to read lines of print.
- Pursuit eye movements allow us to follow an object as it moves.
- Vergence eye movements allow us to move our eyes in different directions2
Changes to these eye movements due to Parkinsons can also result in different kinds of visual difficulties. The inability to control eye movements can lead to involuntary blinking, double vision and other motor issues that can affect visual acuity.
Dry eyes can be treated with drops or ointments, warm wet compresses, but are not generally cured. The blink reflex can be impacted by PD. This manifests as either a slowing of the reflex, appearing as inappropriate staring, dry or burning eyes; and by reduced vision. Blepaharospasm and apraxia are two common eyelid motion issues. Blephararospasms are eyelid spasms that cannot be controlled, cause eyelids to squeeze, and can be relieved with Botox injections. Apraxia is a condition that makes it difficult to open eyes. There are specialized lid crutches and cosmetic tape that can be applied to hold the eyelids open.2

How Does Parkinson’s Cause Vision Issues
Parkinsons is characterized by a loss of dopamine producing cells in the substantia nigra portion of the brain. The reduction of dopamine can affect the visual cortex. So Parkinsons can impair mobility of the eyes just like the limbs. There are several kinds of visual disturbances that may be experienced by people with Parkinsons. Many who experience changes in vision or eye mechanics seek out a consultation from a neuro-opthalmologist, someone who specializes in visual problems associated with neurological disease.2
Treatment For Parkinsons Disease
There is currently no cure for the disease itself, but there are options to treat the symptoms of PD. A combination of medications, physical and/or occupational therapy, support groups, and of course, top-quality vision care can give a PD patient relief for some of their symptoms and tools to help cope with the condition.
Research and clinical trials are continuing as doctors and others in the medical community work towards the goal of finding a cure for PD.
No two patients are alike, and each can experience PD differently from the other, so finding what works for you or your loved one is key. During this Parkinson’s Awareness Month, share your #KeyToPD and give your loved ones hope for a healthy and high quality of life.

What Researchers Have Found
The recent study involved 848 people with Parkinsons and 250 people without the disease.
The participants completed a questionnaire developed to assess visual impairment. The findings are in line with what has been seen in other studies.
A found hallucinations were more common.
Each of those studies included about 90 people with Parkinsons.
These findings are really not that surprising, Beck said. What sets this study apart is the number of individuals surveyed about their own visual issues using this new patient-reported outcome tool.
Dr. Rebecca Gilbert, vice president and chief scientific officer at the American Parkinson Disease Association, said that physicians with experience with people with Parkinsons are very aware of visual difficulties in people with the disease.
But what stood out to her about the new study was the variety of different vision issues that were reported.
The more research that is done, the better, so we can learn more about how prevalent the specific issues are for people and then work to help them in more targeted ways, Gilbert told Healthline.
What Can We Do
Armed with the above knowledge, is there anything we can do about it? I have been implementing various strategies to see if these help and I do strongly believe these are cumulatively benefitting me and reducing my symptoms over time.
The main thrust is to look after our eye health. In this regard, many of the strategies I discussed for blood-brain-barrier health follow over directly:;keeping our bodies very well hydrated;;avoiding inflammation and stress as best we can; making sure our nutritional support is maximized. In terms of nutrition specifically for the eyes, Dr Axe recommends two special anti-oxidants,;Lutein and Zeaxanthin, as well as Zinc and Omega 3 supplementation too. I have been taking all of these for several weeks and do feel my eyes are less sore and dry now. The A, C, E vitamins are also recommended by Dr Axe.
Like most of the rest of our body parts, exercising the eyes and visual brain functions will also be most important to maintaining their health, see:

How Parkinsons Disease Affects The Eye
Parkinsons disease is a progressive degenerative condition of the neurological system.; The majority of Parkinsons effects are on movement, often starting off very slowly and subtly. One of the earliest symptoms is a slight tremor in one or both hands. Other early symptoms include a lack of facial expression and decreased blinking of the eyes, so it looks like the person is always staring. ;
The next stage usually results in difficulty with initiating movement, especially walking.; It frequently looks like it takes a tremendous concentrated effort to initiate walking and the steps often start off very small with a shuffling of the feet.; At the same time, the disease stiffens the muscles of the arms so that when the person is walking there is a noticeable decrease in the swinging of the arms. Speech becomes much softer and writing becomes more of an effort, with handwriting getting smaller and smaller as the disease progresses.
Parkinsons can also affect your visual performance, mainly in two parts of your eyes: the tear film and the ocular muscles.
If you dont blink enough, the tear film begins to dry out in spots and having dry spots next to moist spots results in an irregular film and therefore blurred vision. That is how the decreased blinking frequency in people with Parkinsons disease results in a complaint of intermittent blurred vision.
The majority of these problems do improve if the Parkinsons is treated with medication or even brain stimulation.
Eye Exercises And Parkinson’s Disease
In this regards, I also recommend the work of Dr Eric Cobb of Zhealth Education. Dr Cobb gives a lot of free information on his blog about vision health and provides powerful, but quick exercises to practice daily, as well as running a commercial “vision gym” for pro-athletes. Importantly, Dr Cobb shows us just how – unexpectedly – important the eyes and vision are in direct connection to movement and stress reduction: hence eye exercise has very profound relevance for people with PD. I also recommend stimulation of the cranial nerves which are responsible for the muscles that move the eyes:

Ocular And Visual Disorders In Parkinsons Disease: Common But Frequently Overlooked
This literature search covering 50 years reviews the range of ocular and visual disorders in patients with PD and classifies these according to anatomical structures of the visual pathway. ;It discusses six common disorders in more detail, reviews the effects of PD-related pharmacological and surgical treatments on visual function, and offers practical recommendations for clinical management.
Lower Dopamine Levels & Vision Changes
Seniors with Parkinsons are affected by the loss of a chemical called dopamine, a neurotransmitter that helps with the transfer of signals between nerve cells in the brain. Lower levels of dopamine may also affect a region of the brain called the visual cortex, which processes visual information. These changes could affect eye mobility, which sometimes results in visual impairment. According to the American Parkinson Disease Association , there are three types of eye movement that may be affected by PD: Pursuit eye movements, which allow the eyes to follow objects Saccadic eye movements, which allow the eyes to jump from one target to another Vergence eye movements, which help eyes adjust and maintain clear focus when an object is coming closer
Seniors with severe vision impairment may need assistance to be able to continue living at home. For many seniors in Philadelphia, PA, live-in care is an essential component of aging in place safely and comfortably. However, its important for them to have caregivers they can trust and rely on. At Home Care Assistance, we extensively screen all of our live-in and 24-hour caregivers and only hire those who have experience in the senior home care industry. Our strict requirements ensure seniors can remain in the comfort of home with a reduced risk of injury or serious illness.

Parkinsons Impacts On Vision Can Make Everyday Life More Challenging
Many of the visual symptoms experienced by people living with Parkinsons are mild, and overall visual function can remain quite good with routine examinations by an eye care professional. However, multiple, small abnormalities in combination may become problematic and cause more significant symptoms. For example, difficulty with color vision and loss of contrast sensitivity can make reading signs or walking down patterned stairs difficult. Problems with motion perception and clarity of vision can affect driving.;;

Excessive Watering Of The Eyes
People with Parkinsons can experience this for several reasons, including infrequent blinking due to impaired reflexes. Infrequent blinking stimulates the lacrimal gland resulting in excessive watering. Irritation can also be a cause and this is often eased by using eye lubricants.
If the watering does not settle your neurologist may refer you to an ophthalmic surgeon. Botulinum toxin A injections into the lacrimal gland may also help.

Like Parkinsons Vision Is Linked To The Brain
Vision plays such a critical function that a substantial portion of our brain is made up of pathways that connect our eyes to the visual areas of our brain and the areas that help process this visual information . The primary purpose of the front part of our eyes is to produce the clearest possible image, which is then transmitted to the back part of the eye, called the retina. The retina is made up of nerve cells that communicate via visual pathways using the neurotransmitter dopamine. In addition, we have two eyes with overlapping visual fields, which enables our brain to see the world in three dimensions and process complex visual information. ;

The study enrolled 20 patients who had been newly diagnosed with Parkinsons disease, and 20 age-matched healthy subjects, to assess changes in the visual system associated with the disease. The participants underwent magnetic resonance imaging scans, which researchers used to look at changes in the white and gray matters, as well as ophthalmologic examinations.
They found that patients presented significant changes in the brain structures associated with the visual system, such as changes in the optic radiations, decreased white matter volume and reduced volume of the optic chiasm .
As a consequence, patients experienced visual alterations, such as an inability to perceive colors, decreased visual acuity, and a reduction in blinking, which often led to dry eyes.
According to Arrigo, these changes may appear more than a decade before the motor symptoms associated with Parkinsons disease, which makes them potential biomarkers to diagnose and follow this disease.
The study in depth of visual symptoms may provide sensitive markers of Parkinsons disease, Arrigo said. Visual processing metrics may prove helpful in differentiating Parkinsonism disorders, following disease progression, and monitoring patient response to drug treatment.
