Long-Term Risks of Repeated Head Impacts Among Athletes

Athletes at risk for neuro traumaIf you’ve ever had a concussion or any other type of brain injury, you likely experienced at least some of the symptoms caused by head impacts: headaches, difficulty concentrating, problems with balance, visual problems and even anger management issues.

A single concussion is bad enough, but multiple studies published in National Academies Press (2014) revealed that experiencing as little as two concussions can sometimes lead to serious life-long problems.

Unfortunately, head hits that occur while playing contact sports are common, and the health repercussions of these impacts can be severe.

Here are six long-term risks of multiple concussions and repetitive head impacts:

Chronic Traumatic Encephalopathy (CTE)

CTE is a degenerative brain disease that affects athletes, military veterans and anyone who has experienced repeated brain trauma. Specific proteins (called tau proteins) form clumps in the brain of those with CTE, and these clumps eventually spread throughout the brain, permanently damaging and causing the death of brain cells. Progressive memory and cognition loss, depression, suicidal ideation, poor impulse control, aggression, Parkinsonism, and dementia are among the clinical indications of CTE.

Two case reports published in Neurosurgery involving two National Football League (NFL) players were the first to use the phrase. After long careers playing football in high school, college and professionally, these players suffered from a variety of neuropsychological symptoms.

Evidence suggests that CTE is caused by repeated head blows over a period of years, according to Clinics in Sports Medicine (2011). It’s crucial to understand that you don’t have to have a full-fledged concussion to develop this disease.

Depression

Depression is a mental disorder that affects one’s feelings, thoughts and actions. It can limit a person’s ability to perform at work, at school and at home. Loss of interest in previously loved hobbies, changes in appetite, sleep disturbances and thoughts of death or suicide are all possible symptoms.

Research published in Medicine and Science in Sports and Exercise (2007) discovered a growing linear association between concussion history and being diagnosed with long-term depression. Retired athletes who had three or more concussions were three times more likely than those who had never had a concussion to be diagnosed with depression. Those who had one or two previous concussions had 1.5 times the chance of being diagnosed with depression.

Dementia Pugilistica

Dementia pugilistica, sometimes known as ‘punch-drunk condition,’ is a neurological disease that affects people who have experienced many concussions. The term ‘pugil’ comes from Latin and means ‘boxer’ or ‘fighter.’ The condition was initially diagnosed in boxers in the 1920s. Tremors, sluggish movement, speech difficulties, disorientation, a lack of coordination and memory loss are all prominent symptoms of this disease.

Dementia pugilistica is a kind of CTE that has some microscopic histological characteristics in common with Alzheimer’s disease. While it was first discovered in boxers who were subjected to repeated head hits in a 1973 study published in Psychological Medicine, athletes in other sports may be affected as well.

Neurocognitive Impairments

A concussion’s signs and symptoms can often affect one’s cognitive abilities, resulting in the inability to concentrate, disorientation, irritation and loss of balance. When you have more than one traumatic brain injury in your life, you may be more likely to experience long-term, possibly progressive, disability that impairs your ability to function.

According to the National Academies Press (2014), studies show that recurrent head impacts in football and hockey players cause abnormalities in cognitive function in the brain. In one study, researchers discovered that the impacted athletes had neurocognitive abnormalities in both working and visual memory. In another study, affected football players were found to have problems with impulse control and balance after the sports season concluded.

Slower Neurological Recovery

Despite the fact that millions of people suffer concussions each year, the risks of a prolonged neurological recovery after multiple concussions are still largely unknown. Nonetheless, according to a study published by the National Academies Press in 2014, a history of many concussions may be linked to a longer recovery of brain function after another concussion. According to the findings, repeated concussions may result in lifelong neurocognitive impaieyerment.

This is why it’s crucial to refrain from engaging in any sports or dangerous activities until you’ve fully recovered from a head impact.

Brain Injury and Your Vision

Head trauma and concussions can have major effects on the visual system, despite normal medical imaging results. The group symptoms causing blurred vision, eye coordination issues and dizziness following head trauma is called post-trauma vision syndrome.

Even mild concussions can cause visual dysfunction, such as double vision, accommodative dysfunction, convergence insufficiency, sensitivity to light, eye tracking problems and delayed visual processing.

How Can A Neuro-Optometrist Help?

Neuro-optometry is a branch of optometry that focuses on helping individuals with neurological disorders regain their visual and oculomotor skills. Neuro-optometric rehabilitation therapy aims to improve a patient’s ability to function independently in a multisensory environment.

At Pupila Family Eye Care, we know all too well the challenges that accompany repeated head impacts. To schedule a functional vision evaluation and determine if there is a problem with your visual system, call Pupila Family Eye Care today.

Pupila Family Eye Care offers neuro-optometric rehabilitation therapy to patients from Houston, Bunkerhill Village, Bellaire and Sugarland, Texas and surrounding communities.

Frequently Asked Questions with Dr. Supriya Krishnan

Q: What is a concussion?

  • A: A concussion is a type of brain injury in which a blow to the head causes a momentary loss of brain function. When a person’s brain is violently moved back and forth or twisted inside the skull due to a direct or indirect force, an injury occurs. A concussion causes disruption in brain function and should be treated as a serious injury. Following a concussion, proper healing and recovery time are critical in preventing additional injury.

Q: What does a neuro-optometrist do?

  • A: A neuro-optometrist can assess functional binocularity, spatial vision and visual processing abilities, as well as functional binocularity and visual processing abilities. Following diagnosis, a comprehensive management program will be prescribed. Neuro-optometrists can also diagnose general eye health problems and correct refractive errors with glasses or contact lenses to increase visual acuity.

Could My Headaches Be Vision-Related?

Could My Headaches Be Vision Related 640×350Headaches are a common symptom of several different health conditions, and almost everyone has experienced them at one time or another. In fact, up to 75% of American adults aged 18-65 suffer from headaches every year.

But many don’t realize that chronic or occasional headaches can actually signal a problem with their visual system.

This is especially true for individuals with binocular vision issues such as convergence insufficiency or focusing, which are frequent challenges faced by people who have experienced a traumatic brain injury (TBI), a stroke, or other neurological insults. Fortunately, those who suffer from visual dysfunction can find relief from their headaches by doing a personalized program of neuro-optometric vision therapy.

How Can Vision Problems Cause Headaches?

More real estate in the human brain is dedicated to the sense of vision than any other sense we have. In other words, seeing clearly and comfortably takes serious brain power.

When the visual system is damaged, either from a TBI or other condition, it struggles to function properly and compensates by working overtime. This straining process often results in a headache.

The most common form of visual dysfunction that can result in headaches is binocular vision dysfunction (BVD), a condition in which the eyes are misaligned and therefore don’t point in the same direction. Convergence insufficiency and accommodative dysfunction are other common forms of binocular vision dysfunction that can cause headaches.

Symptoms of Vision-Related Headaches

The only way to tell for certain if your headaches are caused by visual dysfunction is by having your neuro-optometrist perform a functional visual evaluation.

However, the following symptoms are common in patients with visual dysfunction:

  • Frontal headache in the brow area
  • Sensitivity to light
  • Headache pain that impedes daily functioning or memory
  • Dizziness
  • Dull, stabbing or throbbing pain around the eyes
  • Double or blurry vision

In contrast, people suffering from tension headaches usually feel like their forehead is being squeezed by a tight band.

If you or a loved one experiences any of the symptoms of visual dysfunction, know that relief is available. Schedule a consultation with your neuro-optometrist at the first sign of vision-related headaches.

Our Neuro-Optometrist Can Treat Your Vision-Related Headaches

When headaches are rooted in visual dysfunction, healing the visual system often alleviates the accompanying symptoms.

At Pupila Family Eye Care, we help patients who’ve sustained varying degrees of brain injury to rehabilitate their visual system and regain lost visual functioning.

Following a thorough assessment, we will determine if any visual deficit is causing or contributing to your headaches and recommend the next steps to take.

Neuro-optometric rehabilitation therapy is a tailor-made treatment consisting of in-office sessions or specialized prism glasses to help train the eyes and brain to work in unison. It is often prescribed to patients with BVD and other vision problems to correct eye alignment and promote more efficient visual processing. By doing so, some weight is taken off of the visual system and your headaches will likely become less severe or even cease.

If you or a loved one are experiencing headaches, call Pupila Family Eye Care in Houston to schedule a functional visual evaluation and find the relief you seek.

Pupila Family Eye Care offers neuro-optometric rehabilitation therapy to patients from Houston, Bunkerhill Village, Bellaire, and Sugarland, Texas and surrounding communities.

Frequently Asked Questions with Dr. Supriya Krishnan

Q: How common is visual dysfunction after a traumatic brain injury?

  • A: According to the Neuro-Optometric Rehabilitation Association, visual symptoms are found in about 90% of patients who’ve sustained a traumatic brain injury. The most common of these visual symptoms include sensitivity to light, blurred vision, headaches after visual tasks, difficulty reading, difficulty with eye movements and vision loss.

Q: Can neuro-optometric rehabilitation therapy also treat migraines?

  • A: Yes. Visual dysfunction may also produce symptoms of migraines, and treating the problem will help alleviate the pain. Contact your neuro-optometrist if you suffer from migraines to learn if the problem is visual.

How Concussions Can Affect Self-Esteem

How Concussions Can Affect Self Esteem 640X350When you consider the abundant functions of the brain, it’s no surprise that even slight damage to its sensitive tissues can wreak havoc on one’s physical and mental health. Many people experience some degree of emotional distress after suffering a head injury. But how can you tell if your symptoms are serious?

If you or a loved one has ever experienced a concussion, we urge you to learn more about the emotional and physical side effects it may bring, and discover how a neuro-optometrist can help.

What Occurs During a Concussion?

The nerves of the brain are surrounded by soft and fatty tissues, and these fragile nerves are further protected by a layer of fluid and the bony skull. During a sudden and forceful jolt or bump to the head or neck region, such as whiplash, the brain continues to move while the head has stopped moving. This causes the brain to slam into the inner walls of the skull or be shaken back and forth, resulting in a concussion.

This mild form of traumatic brain injury can damage or destroy brain cells, and may also negatively impact the healthy protective tissues surrounding the damaged cells.

Although concussions are considered ‘mild’ because they aren’t life-threatening, they can cause debilitating symptoms like headaches, nausea, vomiting, light sensitivity, blurred vision, balance problems, confusion and emotional distress, among others.

The Link Between Concussions and Self-Esteem

A concussion can negatively affect emotional well-being and self-esteem, both directly and indirectly.

A post-concussion patient may find it difficult to do the things they once enjoyed, like exercising, reading, doing schoolwork or even watching TV. Withdrawing from these activities, even temporarily, may result in feelings of depression, anxiety, and reduced self-worth. When you can’t read, concentrate or complete day-to-day activities as you once did, your limitations can become your main focus.

Concussions can also directly damage areas of the brain responsible for emotional regulation, directly affecting how a person relates to themselves and others.

A study published in Brain Injury (2014) concluded that a person’s self-concept may be impacted following a concussion/traumatic brain injury and that patients should seek treatment for emotional distress following a head injury.

Signs of Lowered Self-Esteem

Because each brain is unique, it’s hard to tell how a concussion will affect the patient, both in the short and long term. Here are a few signs that may reveal emotional distress and reduced self-esteem following a concussion:

  • Withdrawal from social events
  • Avoiding activities that were once enjoyable
  • Lack of motivation
  • Feeling unloved or unwanted
  • Feeling hopeless
  • Negative self-talk
  • Neglecting personal hygiene or appearance
  • Inability to accept compliments
  • Feelings of shame, depression or anxiety

If you or a loved one displays any of the above symptoms, rest assured that help is available.

How We Help Post-Concussion Patients

Recovering from a concussion can be difficult, but neuro-optometric rehabilitation therapy can help by improving the neural communication between the eyes and the brain and how an injured brain processes visual information.

Concussions can significantly affect the eye-brain connections, resulting in symptoms like dizziness, inability to concentrate, light sensitivity and headaches, as well as emotional distress.

A neuro-optometrist can improve the functioning of the visual system in ways that other professionals aren’t trained to, thereby reducing — even eliminating — these debilitating symptoms.

By training the brain and eyes to efficiently work in unison, visual skills will improve and you’ll find it easier to do things like reading, watching TV, using a computer and concentrating without taking as many breaks.

If you or a loved one has ever sustained a concussion, a functional vision evaluation may be called for to rule out visual dysfunction. Even if you’ve been told that nothing can be done by other health care professionals, we may be able to help, even years after the injury.

Let us help you get back to doing the things you love. To schedule a functional visual evaluation, call Pupila Family Eye Care today.

Pupila Family Eye Care offers neuro-optometric rehabilitation therapy to patients from Houston, Bunkerhill Village, Bellaire, and Sugarland, Texas and surrounding communities.

Frequently Asked Questions with Dr. Supriya Krishnan

Q: What other conditions can neuro-optometry treat?

  • A: Neuro-optometrists help patients who’ve survived a stroke, sustained varying degrees of brain injury or have a neurological condition that impedes visual function. All of these conditions can adversely impact visual skills and may cause symptoms that hinder independent functioning and reduce one’s quality of life. By rehabilitating the visual system, a neuro-optometrist can provide relief and promote a greater degree of recovery to these patients.

Q: Do all optometrists provide neuro-optometric rehabilitation therapy?

  • A: No. A neuro-optometrist is a Doctor of Optometry with specialized training in the area of visual system rehabilitation. A general optometrist performs eye exams, diagnoses and manages eye diseases and prescribes corrective lenses to patients. General optometrists do not have the training or experience to perform neuro-optometric rehabilitation therapy.

How Can Lyme Disease Affect Your Vision?

How Can Lyme Disease Affect Your Vision 640Lyme disease is an infection caused by a tick bite infected with the bacterium Borrelia burgdorferi. According to the American Lyme Disease Foundation, the bacteria is transmitted to humans through the bite of infected black-legged ticks.

Lyme disease initially affects the skin near the bite site. However, if left untreated, the infection can extend to the nervous system, joints and other organ systems.

What are the Symptoms of Lyme Disease?

Lyme disease symptoms usually include a rash at the site of the bite that looks like a bull’s eye. Further symptoms may include:

  • Fever
  • Fatigue
  • Joint pain
  • Headache
  • Sore throat
  • Swollen glands

As the disease progresses, one may develop memory loss, attention problems and numbness in the hands, feet and arms.

How Does Lyme Disease Affect Vision?

Lyme disease is typically divided into three stages: early localized, early disseminated and late disseminated. According to the American Academy of Ophthalmology (AAO), Lyme disease can affect the eyes at any stage.

The severity of ocular problems may vary greatly. Different symptoms appear at different phases of the infection. The following are examples of possible Lyme disease eye complications:

Conjunctivitis

Conjunctivitis, often known as pink eye, is an inflammation of the white part of the eye known as the conjunctiva. Conjunctivitis usually appears within the first several weeks of the infection. According to the AAO, conjunctivitis affects roughly 10% of Lyme disease patients. Symptoms include red eyes, itchy eyes and discharge.

Light Sensitivity

For some, light sensitivity is a side effect of Lyme disease. Light sensitivity can also be an adverse effect of several antibiotics used to treat Lyme disease.

Inflammation

Lyme disease patients might potentially develop inflammation of the eye structures. Eye inflammation commonly appears in the third or late stages of the disease. Inflammation of the optic nerve can cause vision loss. Optic neuritis symptoms include eye pain, color vision loss, and flashing lights.

Inflammation of the retinal vessels can also cause impaired vision and floaters. Bell’s palsy-like symptoms might arise if the facial nerves become inflamed. Symptoms may make it difficult to close the eye, causing the cornea to become dry and potentially infected.

Visual Treatment of Lyme Disease

Medical treatment for Lyme disease doesn’t always address Lyme-related visual problems, and without treatment, vision may still be impaired long after medical treatment is completed.

Any inflammation in the body can negatively affect the functioning of the limbs and organs. This is especially true for the brain and the visual system, which are often affected by Lyme disease.

That’s where neuro-optometry can help.

Neuro-optometry evaluates how our eyes and brain function together. When Lyme disease affects that connection, a patient’s balance may be affected, causing their vision and depth perception to be affected as well.

A neuro-optometrist may utilize lenses, prisms and, in some situations, neuro-visual therapy. Neuro-visual therapy is a rehab program for those who have had a neurological incident that has affected their vision and its functioning/processing.

This is especially true in the case of children. Lyme disease can disrupt important developmental cycles, resulting in visual problems and the likelihood of developmental delays and learning difficulties.

If you or your child has been diagnosed with Lyme disease, contact Pupila Family Eye Care, to learn whether it has affected your vision.

Pupila Family Eye Care serves patients from Houston, Bunkerhill Village, Bellaire, and Sugarland, Texas and surrounding communities.

What Is Post Traumatic Vision Syndrome?

What Is Post Traumatic Vision Syndrome 640×350Every year, tens of millions of people around the world sustain a traumatic brain injury (TBI). The majority of TBIs are mild brain injuries, such as concussions. However, concussions and other traumatic brain injuries often result in some degree of visual dysfunction, as nearly half of the brain is dedicated to vision-related processing.

The symptoms of post-TBI visual disturbances fall under the umbrella term post-traumatic vision syndrome (PTVS).

What is Post Traumatic Vision Syndrome?

Post Trauma Vision Syndrome is a disruption of the visual process. This disruption affects the neurological system that innervates the extraocular muscles that control eye movements, as well as the system that regulates focusing. This causes eye problems like difficulty with fixation, binocular fusion, and accommodative function.

What Are the Symptoms of PTVS?

Even with 20/20 vision, a TBI can cause the following visual dysfunctions:

  • Blurred vision
  • Double vision
  • Low blink rate
  • Depth-perception issues
  • Difficulty with eye-tracking
  • Sensitivity to light (photophobia)
  • Eye strain, especially while reading or using a computer

Non-visual symptoms may include:

  • Dizziness
  • Headaches
  • Poor balance
  • Disorientation
  • Difficulty reading
  • Difficulty driving
  • Difficulty concentrating
  • Visual memory problems
  • Difficulty navigating through crowded or tight spaces

How Does a Neuro-Optometrist Treat PTVS?

Your neuro-optometrist will assess your ocular health as well as a wide range of visual abilities, including eye alignment and convergence function, focusing ability, peripheral awareness and more.

If deficits are discovered, your neuro-optometrist will create a neuro-optometric rehabilitation program to improve any visual skills that have been harmed by the brain injury. The program may utilize specialized glasses or prisms to improve spatial and/or binocular vision.

It’s crucial to get treatment for PTVS as soon as possible to minimize deficits and regain quality of life. However, neuro-optometric rehabilitation can be effective even months or years after a TBI.

Schedule a consultation with Pupila Family Eye Care to start treatment for your PTVS today.

Pupila Family Eye Care serves patients from Houston, Bunkerhill Village, Bellaire, and Sugarland, Texas and surrounding communities.

Frequently Asked Questions with Dr. Supriya Krishnan

Q: What is neuro-optometric rehabilitation therapy?

  • A: Neuro-optometric rehabilitation is a personalized program to develop, improve and refine underdeveloped or lost visual skills. This specialized treatment involves eye exercises, techniques and visual aids (i.e. prisms) that improve your visual processing and perception through the strengthening of the eye-brain connection.

Q: Is my concussion impairing my reading?

  • A: Many patients suffering from PTVS experience reading difficulties after their injury. Words might appear to be moving on the page or blurry. Another possible problem is not being able to remember what you just read, even after rereading it several times.

4 Tips To Avoid a Traumatic Brain Injury

4 Tips To Avoid a Traumatic Brain Injury 640×350A traumatic brain injury, or TBI, is an injury to the brain caused by physical trauma, typically a sudden bump or blow to the head.

Concussions — a mild form of brain injury — are very common and represent approximately 80% of all TBI incidents. A concussion is a temporary loss of brain function caused by the brain bouncing around in fast motion within the skull, sometimes producing chemical changes or damaging the functioning of the brain cells.

Moderate to severe TBIs can cause loss of consciousness— from a few minutes to several hours.

Any TBI, whether mild or severe, can affect cognitive abilities and cause visual symptoms such as:

  • Double vision
  • Light sensitivity
  • Partial or total loss of vision
  • Weakened eye muscles

4 Tips for Avoiding a Traumatic Brain Injury

One of the best ways to protect yourself from a concussion or more serious TBI is to put safety first, whatever your activity.

Wear Protective Sports Gear

Approximately 69 million TBIs occur each year worldwide, of which about 50% are sports-related. Wearing protective eyewear and a helmet when playing baseball, football, basketball, hockey or any other sport, can help prevent serious injuries, especially in children.

Wear Sunglasses

Glare from the sun can temporarily blind you while driving, walking across the street — during any activity, really. Wearing sunglasses is a simple way to reduce glare and prevent glare-related accidents.

Polarized sunglasses filter intense light that reflects off surfaces like water, glass, sand, snow and pavement, preventing glare from entering your eyes. Make sure the sunglasses you choose also offer 100% UV protection. Photochromic lenses are a good choice for people who wear prescription glasses since they darken when outdoors and become clear again indoors.

Pay Attention To Your Surroundings

As basic as it may seem, people often fail to pay attention to their surroundings. When walking, driving, or doing any other activity, try to minimize distractions. Stand still while speaking on your cell phone or texting. When you’re walking outside, keep an eye out for sidewalk cracks as well as overhanging branches and other sharp items or debris that could be hazardous.

Don’t Forget to Wear Your Seatbelt

For years, parents and doctors have been drumming this into our heads, and for good reason! The #1 way to prevent or minimize an injury from a car accident is by wearing a seatbelt.

According to the National Center for Biotechnology Information National Library of Medicine, one-quarter of all TBIs in North America are caused by road accidents. Those numbers rise to more than 50% in Southeast Asia and Africa.

How a TBI Affects Vision

A traumatic brain injury can impair your vision, causing light sensitivity, double or blurry vision, and persistent eye strain. In many cases, activities like reading a book, driving a car or watching TV can become much more challenging — or impossible — as a result of a TBI.

According to Clinical and Experimental Optometry, 90% of TBI patients suffer from visual dysfunction, making it all the more crucial to take precautionary measures to stay safe.

Neuro-Optometric Rehabilitation Can Help With Brain Injuries

Neuro-optometric rehabilitation is a personalized treatment program for patients with visual deficits due to physical disabilities and TBIs. The goal of neuro-optometric rehab is to minimize visual disability so that a patient can continue to perform daily activities, whether it’s learning in a classroom or being able to function in the workplace.

A neuro-optometric rehabilitation optometrist evaluates many functions of the visual system, such as how the eyes work together. Treatment options may include the use of various filters and prisms, and visual exercises to strengthen the brain-eye connection.

If you or a loved one displays double vision, light sensitivity, dizziness or any other TBI-related visual or balance-related symptoms, contact Pupila Family Eye Care immediately. Following evaluation, Dr. Supriya Krishnan may offer a customized neuro-optometric rehabilitation program to help regain any lost visual skills.

3 Ways Neuro-Optometry Can Help Stroke Survivors

3 Ways Neuro Optometry Can Help Stroke Survivors 640Approximately 15 million people around the globe suffer from a stroke each year. An alarming two-thirds of stroke survivors experience some degree of visual dysfunction after the incident.

These problems can range from irritating to debilitating and can seriously affect a person’s quality of life and ability to function.

Thankfully, there is hope for stroke survivors who suffer from stroke-related vision problems.

At Pupila Family Eye Care, we are dedicated to helping post-stroke patients heal their visual system for long-lasting relief and a better quality of life.

Below, we’ll explore how a stroke can impact vision and what a neuro-optometrist can do to help.

What is a Stroke?

A stroke occurs when insufficient oxygen is delivered to the brain tissue, either due to leaking or bursting blood vessels, or a blockage within the blood vessel.

Serious brain damage can occur within minutes of a stroke, making early intervention crucial.

Signs of a stroke include:

  • Paralysis
  • Numb or weak limbs
  • Slurred speech
  • Confusion
  • Trouble walking
  • Dizziness or loss of coordination

Because a large portion of the brain is involved with vision, a stroke can also affect the eyes and visual processing.

How a Stroke Can Affect Vision

If a stroke occurs in the areas of the brain that control the eye, it can cause:

  • Blurred vision
  • Visual field loss
  • Double vision
  • Dry eye syndrome
  • Sensitivity to light
  • Nystagmus — rapid, uncontrolled eye movements

When a stroke affects the areas of the brain responsible for visual processing, it can cause:

  • Visual neglect — when the patient ignores stimuli from a portion of their visual field
  • Visual hallucinations
  • Poor depth and movement perception
  • Difficulty recognizing objects or people

3 Ways a Neuro-Optometrist Can Help Stroke Survivors

1. Identify and Diagnose Any Visual Dysfunction

A neuro-optometrist has the training and experience required to thoroughly identify, diagnose and treat even slight visual dysfunction that may be causing symptoms.

Your neuro-optometrist will perform a functional visual evaluation to assess neurological vision-related complications and identify the type of vision loss caused by the stroke.

 

2. Rehabilitate the Visual System

Neuro-optometric rehabilitation therapy includes visual exercises that retrain the brain and eyes to work together.

During a stroke, certain neural connections may become damaged. Neuro-optometric rehabilitation aims to restore those connections and heal the visual system for long-lasting results.

3. Prescribe the Correct Lenses or Prisms, As Needed

A neuro-optometrist can prescribe specialized lenses or prisms that aid in the therapeutic process. Prism lenses shift images into the functioning part of a patient’s visual field, or, in the case of double vision or visual neglect, unite the images the two eyes are sending to the brain. In some cases, prisms can instantly relieve symptoms like disorientation or double vision.

Some patients only visit an occupational therapist or physical therapist after a stroke—and while these therapies are often necessary and helpful, they cannot treat the visual system or prescribe prisms.

How We Can Help

Stroke survivors deserve the best in rehabilitative care. That’s why we are passionate about restoring their independence and offering relief from incapacitating visual symptoms.

Furthermore, neuro-optometric rehabilitation therapy offers the added benefit of diminishing vertigo and depression and increasing confidence levels.

If you or a loved one has suffered a stroke, we can help. To schedule your functional visual evaluation, contact Pupila Family Eye Care today.

Pupila Family Eye Care serves patients from Houston, Bunkerhill Village, Bellaire, and Sugarland, all throughout Texas.

 

Frequently Asked Questions with Dr. Supriya Krishnan

Q: #1: Other than stroke patients, who can benefit from neuro-optometric rehabilitation therapy?

  • A: Neuro-optometric rehabilitation therapy can help any person suffering from visual dysfunction after a head injury, traumatic brain injury or stroke, or anyone with neurological conditions that impact their vision. If you experience any symptoms associated with visual dysfunction like dizziness, disorientation, headaches, nausea or difficulty concentrating— it may be time to visit your neuro-optometrist.

Q: #2: Can neuro-optometry help if the stroke occurred months or years ago?

  • A: The best time to start treatment is as soon as possible following a stroke or head injury, but treatment can also be effective years later. The basis of neuro-optometry is neuroplasticity—the brain’s ability to change and build new neural connections. As long as a person is alive, there is potential to heal their visual system.
