How Parkinsons Affects Your Eyes
Eye Movement Problems
There are three fundamental types of eye movements.
- Pursuit eye movementsallow the eyes to travel together to follow a moving target in the horizontal or vertical direction.
- Saccadic eye movements are the rapid eye movements that allow the eyes to quickly jump to a new target. They are important when reading as the eyes need to jump from the end of one line and to the beginning of the next.
- Vergence eye movements are used when the target is coming towards or away from a person. When the target comes towards a person for example, the eyes have to move slightly together, or converge, to keep vision of the target clear.
In PD, the saccades tend to be slow, which means reading can be difficult if the eyes are unable to find the correct place on the next line. If a person has Levodopa-induced dyskinesias, the saccades can become fast and erratic which can also be problematic.
Another common eye movement issue for people with PD is difficulty with vergence eye movements. In PD, the eyes are often not able to come together sufficiently as a target draws near. This is called convergence insufficiency, which can cause double vision, especially when focusing on near tasks. This problem can also affect a persons ability to read.
Eye movement solutions
In terms of complementary and alternative therapies, art therapy has been seen to alleviate some of the vision effects associated with Parkinsons disease.
Abnormalities of blinking
External eye disease
Supranuclear Control Of Spontaneous Blinking
Normal spontaneous blinking occurs at a rate of 1520 blinks/min this frequency varies considerably between individuals and is somewhat higher in women than men . During a blink, the LPS abruptly stops firing, and the palpebral portion of the OO contracts, resulting in active eyelid closure . As soon as eyelid closure is complete, the OO abruptly stops firing, basal activity of the LPS resumes and the eyelid opens . The duration of eyelid closure in blinking must be very brief to avoid disrupting visual input. Blinking can also occur reflexively in response to various stimuli, including visual threat, bright light, tactile stimulation of the cornea or eyelids, and loud noise. With the exception of visual threat, which involves the occipital cortex, all are mediated by brainstem reflex arcs.
The anatomic pathways through which LPS and OO function is coordinated during blinking remains poorly understood, but the SC is thought to play a key role. The SC sends projections to both the facial motor nucleus and the supraoculomotor area directly overlying the CCN . It also receives afferent input from the trigeminal sensory nucleus and dorsal midbrain . Inhibitory microstimulation of the SC in primates has been shown to both suppress spontaneous blinking and increase sensitivity to blink reflexes .

- It has also been associated with multiple system atrophy, Parkinsonâs disease, and frontal lobe injuries or stroke. Although often confused with upper eyelid ptosis, ALO occurs in the absence of lid levator weakness. The lids typically open more easily during reflex blinking and can be assisted to open by various maneuvers such as brushing.

- Blepharospasm is a focal dystonia. Dystonia is a disease affecting the motor system of the brain that leads to involuntary movements and postures. In its focal forms, it affects only one part of the body. In blepharospasm, the dystonia affects the eyelid closing muscles. Blepharospasm is characterized by frequent blinking or sustained closure.
- The most common negative reaction to injections to your face is a droopy eyelid, also called ptosis or blepharoptosis. Most people donât have this problem. Around 5% of people who get Botox will.

Treatment Options & Surgery Risks
If the ptosis is mild and there is no underlying disease to address, treatment may not be necessary.
Some people seek treatment for cosmetic reasons or if they have vision problems as a result of ptosis.

How Can The Eye Muscle Problem Be Treated
Treatment for the eye muscle problem usually involves medications and/or surgery. Eyelid surgery is the most common type of surgery. It is usually used to correct a problem such as droopy eyelids, ptosis , or a misaligned eye. Eyelid surgery can be done using a variety of methods, including: incisions in the lower lid, injection of Botox into the orbicularis oculi muscle , and use of a laser.
Droopy eyelid is a common problem that can also be corrected with ptosis correction. Ptosis correction surgery restores the normal upward position of the eyelid, which can help to improve vision and reduce droopy eyelid symptoms.
Eyelid droopiness can be caused by a number of factors, and if the cause is not addressed, it can lead to vision problems and other health problems. We hope this information keeps you aware, and do visit an ophthalmologist if you are suffering from droopy eyelids!

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.

What Is The Eye Muscle Problem
Droopy eyelids are a problem that many people experience. This problem is caused by a lack of eye muscle strength. When the eye muscles dont have the strength to keep the eyelids up, they droop down. This can be a result of age, injury, or genetics. There are many different medical reasons that cause the eyelids to fall, and each person experiences it differently. Some people may experience it as a result of medication or illness, while others may simply have weaker eye muscles. If you are experiencing droopy eyelids and would like to know more about what might be causing them, speak with your doctor or an ophthalmologist like Ava Eye Clinic.
Neurodegenerative Diseases Associated With Eyelid Retraction
Eyelid retraction is seen in virtually all patients with PSP and is said to result in a characteristic surprised appearance or stare. By contrast, it has only been rarely reported in PD . Eyelid retraction is also a classic finding in SCA3 in one study, 65% of patients with SCA3 had eyelid retraction resulting in a bulging eyes appearance compared to less than 5% of patients with other autosomal dominant SCAs . Interestingly, while midbrain atrophy is the pathologic hallmark of PSP, it is rarely seen in SCA3.

Causes Of Droopy Eyelid: A Doctors View
Posted By: Dr. C.June 4, 2022
Droopy eyelid is a common and often frustrating problem that affects many people. This can be a result of a variety of underlying conditions, but it can usually be treated with conservative measures. In this article, we will discuss the various causes of droopy eyelid and provide a doctors view on how to best treat the problem.
Overview Of Voluntary Eyelid Control
There is evidence to suggest that at least a subset of patients with AEO may have a form of dystonia. As many as one-third of patients with AEO report a geste antagoniste, typically a light touch of the eyelids, that allows for temporary eye opening . Blepharospasm may co-exist, and AEO is occasionally unmasked by chemodenervation of the OO to treat blepharospasm, mistaken as treatment failure or ptosis due to the spread of botulinum toxin and treated with the addition of botulinum toxin to the pretarsal OO . While the OO is by definition clinically and electrophysiologically silent in AEO, selective electromyographic recordings of the pretarsal portion of the OO have revealed the presence of abnormal activity in some patients . Because of its technical challenges, this finding has been difficult to replicate on a larger scale, and it is unclear if these patients truly have AEO, a subtle variant of blepharospasm, or a distinct entity altogether that some have termed OO motor persistence.

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.
What Is The Other Structural Problem With The Eyelids
The other structural problem with the eyelids is a problem with the fatty tissues that cover the eyelids.
One problem that can be caused by fatty tissues is to do with the droopiness. This is when the fatty tissues cause the eyelid to hang lower than it should. This can be caused by a lot of different things, but one common cause is weight gain or loss.
Another possible cause is a medical condition called blepharopharyngitis. Blepharopharyngitis is an inflammation of the tissue that covers the inside of your eyelids, and can make them droopy.
Other causes include muscle injury, and diseases like thyroid problems or diabetes. Its important to get checked out by a doctor if you notice your eyelids are drooping for no reason, as there may be a more serious underlying issue that needs to be addressed.

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

What Are The Most Common Causes Of Droopy Eyelid
Many people experience droopy eyelid because of various reasons. The most common causes are age, genetics, and neurological conditions. Other causes can include medications, eye exercises, and stress. If your eyelids are droppy, it is important to consult with a doctor to find out the specific cause and determine the best course of action.
There are a variety of underlying causes of this problem, but the most common are eye muscle problems and other structural problems with the eyelids.

Who Gets Droopy Eyelid
There are many different possible causes of droopy eyelids, ranging from natural causes to more serious conditions. Your doctor will be able to help you figure out whats causing the issue.
Anyone can get droopy eyelids, and there arent substantial differences in prevalence between men and women or between ethnicities.
However, its most common in older adults because of the natural aging process. The levator muscle is responsible for lifting the eyelid. As you age, that muscle can stretch and, as a result, cause the eyelid to fall.
Keep in mind, though, that people of all ages can be affected by this condition. In fact, babies are sometimes born with it, though this is rare.
Sometimes the exact cause is unknown, but other times it may be due to trauma. It can also be neurological.

When Does A Person Need Treatment
In some cases, a droopy eyelid may resolve spontaneously. If ptosis is present but not causing any functional problems, a person may not need any treatment at all.
Treatment options depend on what is causing the droopy eyelid, how it is affecting the person, and the persons age.
When a child has a droopy eyelid, for example, doctors often recommend surgery. This is because the droopy eyelid is more likely to affect the childs vision.
Before suggesting how to manage ptosis, a doctor may assess the person using the following:
Daily doses of the medication oxymetazoline can affect the levator muscle.
A doctor may suggest trying these options before they recommend surgery.
There are several types of surgery a person may undergo for ptosis, depending on the cause.
What Is Drooping Of The Eyelids
A droopy of the eyelid is a naturally occurring issue in some people. It creates a characteristic sleepy eye look. And sometimes droopy eyelid can then become beyond just the cosmetic aspect and can also let you face some difficulties with the eye vision, most probably in the case of ptosis.
The term ptosis is a medical term which is generally referred to the drooping of the upper eyelids. However, drooping eye used to present at birth and so it does not hamper vision in any way and is considered to be as ptosis.
This thing should not be confused with the swelling of the dermis skin due to an allergic reaction.
A droopy eyelid is actually a sagging eyelids in the upper part. The corner of the upper eyelid may be quite lower than it should be in ptosis or there may be quite excess baggy eyelids. However, the droopy eyelid is the combination of both the conditions. Your skin gradually loses its elasticity and starts to droop all over as you age but the effect is most obvious on your face most probably around the eyes.

Ptosis Due To Levator Weakness
Most other inherited myopathies spare the eyelids and extraocular musculature. Notable exceptions include oculopharyngeal muscular dystrophy and myotonic dystrophy. The pathologic hallmark of OPMD on muscle biopsy is filamentous intranuclear inclusions composed of the misfolded polyalanine expanded PABPN1 protein , though aggregates of dysmorphic mitochondria have also been observed , which may be the mechanism by which the LPS is preferentially affected. A striking feature of myotonic dystrophy is that while it is an autosomal dominant disease, the phenotype is more severe when it is inherited maternally rather than paternally, and congenital presentations are seen exclusively in the children of affected mothers . These observations led to the hypothesis that the pathogenesis of myotonic dystrophy may be influenced by mitochondrial factors. However, several mitochondrial DNA sequencing studies have failed to detect any variants associated with phenotype severity . Congenital myasthenic syndromes also frequently cause ptosis. They are caused by mutations in a number of genes involved in neuromuscular transmission, both presynaptic and postsynaptic .
