How Does Parkinson’s Affect Vision
Parkinson’s can have a significant impact on vision and ocular health. Patients with PD often find themselves unable to control blinking. Blinking is good for the eyes as it moisturizes the surface and clears it from foreign substances. Less blinking can cause Dry Eye Syndrome, resulting in itchy, red, or gritty-feeling eyes. Other people blink too much or can;t keep their eyes open.
In more serious cases, Parkinsons affects the nerves that help us see. Someone with PD may experience blurry vision, double vision, difficulty seeing color and contrast, problems with focus, and other visual symptoms.
In addition to the inherent impact of the disease, some of the medications used to treat Parkinsons symptoms have known side effects including dry eyes, blurred eyesight and even hallucinations in advanced PD.
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:
Is Vision Specifically Affected In Pd Dementia
Many of the oculo-visual features present in early and middle stage PD will become more severe if the patient develops PD dementia. However, some features appear to be particularly exacerbated in PD dementia including deficits in colour vision and changes in pupillary function . In addition, there are visual features which may be particularly characteristic of PD dementia. First, prominent visual hallucinations are significantly more frequent in PD dementia than PD . Second, severe eye movement problems are more likely to be present in PD dementia and to become more extensive with declining cognitive function . Third, defects in visuospatial orientation are likely to be greater in PD dementia especially when associated with greater cortical atrophy . Many additional visual features, already detected in PD, are likely to be present in a more severe form in PD dementia.

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.
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:

Saccadic And Smooth Pursuit Eye Movements
Electro-oculography recordings have also been made before and after apomorphine treatment in early stage patients suggesting that smooth pursuit movements could be affected during the prodromal phase . In addition, patients with PD often have difficulty in sustaining repetitive actions and hence, smooth pursuit movements exhibit a reduction in response magnitude and a progressive decline of response with stimulus repetition.
Living With Parkinson Disease
These measures can help you live well with Parkinson disease:
- An exercise routine can help keep muscles flexible and mobile. Exercise also releases natural brain chemicals that can improve emotional well-being.
- High protein meals can benefit your brain chemistry
- Physical, occupational, and speech therapy can help your ability to care for yourself and communicate with others
- If you or your family has questions about Parkinson disease, want information about treatment, or need to find support, you can contact the American Parkinson Disease Association.

Coping With Vision Problems From Parkinson’s
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.
The Use Of Levodopa And Peripheral Neuropathy
There are reports in the literature that levodopa use may increase the risk of peripheral neuropathy, although other studies suggest that this is not the case. There are studies that demonstrate for example, that cumulative Levodopa exposure correlates to prevalence of PN in people with PD. Other studies however, demonstrate no difference in the prevalence of PN whether the person was treated with Levodopa or not, suggesting that Levodopa treatment does not play a role in development of PN.
Another area of research that emerges from the literature is the potential role of Vitamin B12 deficiency in the development of PN in those with PD. Some studies suggest that Vitamin B12 deficiency is a more common cause of PN among those with PD than those with PN who do not have PD.
There is also research that suggests that levodopa treatment may contribute to PN through impairment of Vitamin B12 metabolism, leading to Vitamin B12 deficiency. Taking COMT inhibitors such as Entacapone may protect against this complication.
Regardless, if PN is diagnosed in anyone, whether they have PD or not, and whether they take Levodopa or not, Vitamin B12 and various other markers of Vitamin B12 metabolism should be tested. If Vitamin B12 levels are low or even low-normal, a person should take Vitamin B12 supplementation, which may help with the symptoms of PN. Other causes of PN, many of which can be checked with various blood tests, should be investigated as well.

Involuntary Eye Closure & Eyelid Drooping
Its not uncommon for seniors with Parkinsons disease to experience involuntary eye closure . Eyelids may also droop due to muscle weakness or nerve damage caused by the disease. Both of these issues can narrow the field of vision and contribute to difficulty with navigation and coordination. Vision problems of this nature also increase the risk of falling for seniors with PD. Under certain circumstances, Botox injections may be recommended to address issues with eyelid drooping.
If your loved one is living with vision problems and needs assistance with daily tasks, help is available. Seniors can face a variety of challenges as they age, many of which can be mitigated with the help of professional in-home caregivers who provide high-quality elderly home care.Trust Home Care Assistance to help your elderly loved one age in place safely and comfortably.
Does Parkinsons Disease Affect Vision
By Kathy Herrfeldt 9 am on March 15, 2021
When people think about Parkinsons, they typically focus on the loss of motor skills. However, the disease can also impact vision and make it difficult to complete various tasks that dont involve motor function or mental health.

Treatment
Ultimately we hope to improve these visual symptoms. We hope that our insights will enable people with Parkinsons to take greater control of their lives.
Molecular And Neurotransmitter Deficits In Pd
Although dysfunction of the dopamine neurotransmitter system has long been associated with the pathophysiology of PD accumulating evidence suggests that PD is a multisystem degeneration . Dopamine is an important neurotransmitter in the retina being present in amacrine cells along the inner border of the inner nuclear layer , and accumulated by interplexiform cells . Two types of amacrine cells appear to be involved: type 1 cells which send ascending processes to synapse with -aminobutyric acid interplexiform cells in stratum 1 of the INL and type 2 cells which have dendrites stratifying above those of the type 1 cells of the inner plexiform layer . Dopamine may be involved in the organisation of the ganglion cell and bipolar cell receptive fields and may modulate the physical activity of the photoreceptors . In addition, dopamine is involved in the coupling of the horizontal and amacrine lateral system . Thinning of the retinal nerve fibre layer has been recorded in PD . In particular, significant thinning of INL in parafoveal regions has been observed, especially in those patients exhibiting visual hallucinations but without overt signs of dementia .

Blurred Vision And Difficulty Focussing
Some Parkinsons medications, in particular anticholinergics, can cause blurred vision and difficulty focussing. You may find your vision is blurred if you start taking anticholinergics and that this goes away when your body gets used to the new drug. This can also happen if you have been taking anticholinergics for some time but your dose is altered. If necessary your doctor may adjust your medication regime.
Talk with your doctor if blurred vision does not improve – or worsens – over time, so that your medication can be adjusted if necessary. If you wear reading glasses, a slight adjustment may also help. Your optician or optometrist should be able to help with this.;
Vision Problems Common In Parkinsons Disease
We were unable to process your request. Please try again later. If you continue to have this issue please contact .
People with Parkinsons disease have a higher prevalence of ophthalmologic symptoms than those without the disease, according to research published in Neurology, the medical journal of the American Academy of Neurology.
It is especially important for people with Parkinson’s to have the best vision possible because it can help compensate for movement problems caused by the disease, and help reduce the risk of falls,Carlijn D.J.M. Borm, MD, of the Radboud University Medical Centre in Nijmegen, The Netherlands, said in a press release. Our study found not only that people with Parkinson’s disease had eye problems that go beyond the aging process, we also found those problems may interfere with their daily lives.
Borm and colleagues conducted an observational, cross-sectional study across multiple centers in the Netherlands and Austria as part of a larger study on visual impairments in patients with Parkinsons disease.
The researchers evaluated the prevalence and clinical effects of ophthalmologic symptoms in adults using participant responses to the Visual Impairment in Parkinsons Disease Screening Questionnaire. The questionnaire included questions on demographic information and visual hallucinations, and assessed the four domains of ophthalmologic disorders ocular surface, intraocular, oculomotor and optic nerve.

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
What Are The Complications Of Parkinson Disease
Parkinson disease causes physical symptoms at first. Problems with cognitive function, including forgetfulness and trouble with concentration, may arise later. As the disease gets worse with time, many people develop dementia. This can cause profound memory loss and makes it hard to maintain relationships.
Parkinson disease dementia can cause problems with:
- Speaking and communicating with others
- Problem solving
- Forgetfulness
- Paying attention
If you have Parkinson disease and dementia, in time, you likely won’t be able to live by yourself. Dementia affects your ability to care of yourself, even if you can still physically do daily tasks.
Experts don’t understand how or why dementia often occurs with Parkinson disease. Its clear, though, that dementia and problems with cognitive function are linked to changes in the brain that cause problems with movement. As with Parkinson disease, dementia occurs when nerve cells degenerate, leading to chemical changes in the brain. Parkinson disease dementia may be treated with medicines also used to treat Alzheimer’s disease, another type of dementia.

Why Loss Of Sense Of Smell Occurs
96% of newly diagnosed people with Parkinsons will have lost some ability to smell. Little is confirmed about what causes hyposmia, the loss of smell. One popular theory in Parkinsons research has to do with the protein alpha-synuclein, which is found in clumps in all people with Parkinsons in the part of the brain affected by Parkinsons. This region of the brain is also very close to the Olfactory Bulb, which is responsible for our sense of smell.;
Symptoms Of Peripheral Neuropathy
The symptoms of PN can be non-specific, and a person therefore may not be able to distinguish on their own whether his/her symptoms are due to PN or another condition. PN, however, often results in specific findings on a neurologic exam, such as decreased sensation to pin prick or vibration or the lack of ability to discern which way a toe is being pointed without looking. Other tests such as Electromyogram and Nerve conduction studies may be necessary to confirm the diagnosis. Small fiber neuropathy which typically causes pain, burning, tingling and/or numbness in the feet, may have normal EMG and NCS and a skin biopsy may be necessary to confirm the diagnosis. With the appropriate examination and supportive tests however, a neurologist should be able to distinguish the symptoms of peripheral neuropathy from other conditions, including PD, that may cause similar symptoms.
There are many known causes of PN including diabetes, vitamin deficiencies, certain infections, and autoimmune diseases. Many of these causes can be treated, so it is important to know if you do have PN and what the cause is. There are those people; however, who have the signs and symptoms of PN, but no known cause can be identified.

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;
