What Are The Primary Motor Symptoms Of Parkinsons Disease

Eye Problems and Visual Disorders in Parkinsonism Dr. Rana

There are four primary motor symptoms of Parkinsons disease: tremor, rigidity, bradykinesia and postural instability . Observing two or more of these symptoms is the main way that physicians diagnose Parkinsons.

It is important to know that not all of these symptoms must be present for a diagnosis of Parkinsons disease to be considered. In fact, younger people may only notice one or two of these motor symptoms, especially in the early stages of the disease. Not everyone with Parkinsons disease has a tremor, nor is a tremor proof of Parkinsons. If you suspect Parkinsons, see a neurologist or movement disorders specialist.

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.

Vision: More Than Meets The Eye Tricks To Aid Pd Patients

Retired neurologist and young onset Parkinsons patient, Dr. Maria De León reminds us that vision is integral to our quality of life and safety, especially with respect to driving. She lists 11 common eye problems with PD, and a few uncommon ones. They may be helped by adjusting medications, with special lenses, or artificial tears. See your doctor to find out.

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.

New Insights Into Vision Problems In Parkinsons

Parkinsons disease: Dry eyes, double vision, and trouble reading are ...

Damian McNamara

Visual problems are significantly more common in patients with Parkinson disease and adversely affect quality of life by interfering with normal daily activities, new research suggests.

In a study with more than 1000 participants, more than 82% of the patients with PD had at least one ophthalmologic symptom, in comparison with 48% of matched control persons who did not have the disease. Symptoms included double vision, blurriness, and watery eyes.

In addition, 52% of respondents with PD reported that their eye symptoms restricted reading 33% reported that their symptoms had a negative effect on driving and 28% experienced more difficulty watching television or working on a computer.

Our findings emphasize a great need for a much better awareness of the debilitating ocular disorders that are commonly present in patients with Parkinsons disease. This greater awareness is needed for physicians, patients, and caregivers, lead author Carlijn D. J. M. Borm, a neurology resident at the Center for Expertise for Parkinson and Movement Disorders, Radboud University Medical Center, Nijmegen, the Netherlands, told Medscape Medical News.

The results add new knowledge about the prevalence of a wide range of ocular symptoms and, importantly, on the effect of these symptoms on daily life functioning, she noted.

The findings were March 11 in Neurology.

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.

Ways Parkinsons Disease Affects The Eyes

According to the Mayo Clinic, Parkinsons Disease is a progressive nervous system disorder that affects movement. Symptoms start gradually, sometimes starting with a barely noticeable tremor in just one hand. Tremors are common, but the disorder also commonly causes stiffness or slowing of movement. There many other prevalent symptoms and complications of Parkinsons and the eyes are no exception.


Diplopia is the medical term given to double vision. Unfortunately, it can be a common occurrence in patients with Parkinsons Disease. It may occur in up to 30% of PD patients. The exact mechanism for the cause of the double vision in not fully understood. The double vision may occur in straight-ahead gaze or in a particular direction of gaze . Another very common source of double vision in PD is convergence insufficiency, which is when the eyes are unable to converge normally for up close visual activities like reading. This would produce double vision when only reading.

Double vision may be helped with PD medications if the person is not actively being treated. Interestingly, some PD medications themselves may cause double vision. If the double vision is consistent, the optometrist may be able to prescribe prism in the patients glasses to help compensate for the misalignment causing the double vision. If the double vision is due to convergence insufficiency, a separate pair of reading glasses with prism compensation may be best.

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 Parkinsons.

After checking the vision in each eye, the doctor will carefully examine the movements of each eye. The doctor will also use different methods to measure the alignment of the two eyes in different positions. The results of these tests will allow an understanding of whether the problem is caused by the eye muscles, the nerves that connects to the muscles, or parts of the brain that control eye movements.

Vision Problems Common In Older Parkinsons Patients In Us Study Finds

Problems with vision are more common in older people with Parkinsons disease than in others of a similar age, and are linked with poorer health outcomes, a study based on U.S. Medicare records found.

Fewer than 60% of the more than 285,000 Parkinsons patients whose data were analyzed, however, had annual eye exams.

The study, Visual Impairment Is More Common in Parkinsons Disease and Is a Risk Factor for Poor Health Outcomes, was published in Movement Disorders.

Difficulties with vision at older ages Medicare beneficiaries in the U.S. are overwhelmingly people age 65 or older are associated with a poorer quality of life, including a greater risk of falls, depression, anxiety, and dementia, the study noted.

With vision problems increasingly recognized as a nonmotor symptom of Parkinsons, researchers at the University of Pennsylvania investigated Medicare claims data from 201014, looking at the prevalence of these problems and outcomes in this patient group.

Specifically, they sought to determine the prevalence of moderate to severe visual impairment in Parkinsons patients, and how poorer vision related to disease outcomes. They also explored patterns of eye examinations given patients.

Because most causes of visual impairment are either preventable or treatable, they wrote, findings could lead to better healthcare approaches in patients at greater risk for diminished vision.

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.

Ocular Motor And Sensory Function In Parkinson Disease


The purpose of this paper is to evaluate the effect of dopaminergic medication and deep brain stimulation on ocular function in Parkinson Disease and to measure vision-elated quality of life in subjects with PD. The conclusion is that convergence ability is significantly poorer in PD subjects in both on and off states compared with controls, but significantly improves with systemic dopaminergic treatment. Ocular motor function in PD subjects fluctuates in response to treatment, which complicates ophthalmic management. PD subjects have a significant reduction in vision-related quality of life, especially near activities, that it not associated with visual acuity.

Serious Eye Problems Common In People With Parkinsons

WEDNESDAY, March 11, 2020 People with Parkinsons disease often have eye problems, which can interfere with their daily activities and increase their risk for falls, researchers say.

It is especially important for people with Parkinsons 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, according to the author of a new study, Dr. Carlijn Borm of Radboud University Medical Center in Nijmegen, the Netherlands.

The study included 848 people with Parkinsons who had symptoms for an average seven years, and 250 people without the disease. The average age in both groups was 70.

Participants were asked about vision and eye problems such as blurry vision, dry eyes, trouble with depth perception and problems adjusting to rapid changes in light.

In all, 82% of people with Parkinsons reported one or more eye problems compared to 48% of others, and people with Parkinsons reported daily symptoms much more often, according to the report published online March 11 in the journal Neurology.

In addition, 68% of people with Parkinsons said that eye and vision problems interfered with daily activities, such as driving a car, working on a computer, walking or personal care, compared to 35% of people without the disease.

Everyone Needs Regular Eye Exams

Ophthalmic manifestations of Parkinsons disease

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.
