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 Associates in Eye Care to start treatment for your PTVS today.

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 Associates in Eye Care immediately. Following evaluation, our optometrists may offer a customized neuro-optometric rehabilitation program to help regain any lost visual skills.

Frequently Asked Questions with our optometrists

Q: What Does a Neuro-Optometrist Do?

A: A neuro-optometrist diagnoses general eye health problems and corrects refractive errors to improve visual acuity, as well as assess functional binocularity, spatial vision, and visual processing abilities.

Q: What causes a TBI?

A: Traumatic brain injuries can occur during everyday activities like walking, swimming, hiking, running or playing competitive sports.

The most common causes of TBIs are:

  • Being struck by an object
  • Falls
  • Motor vehicle accidents
  • Sports injuries

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 Associates in 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 Associates in Eye Care today.

Associates in Eye Care serves patients from Somerset, Russell Springs, Jacksboro, and Jellico, all throughout Southern Kentucky and North Tennessee.

 

Frequently Asked Questions with our optometrists

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.

4 Ways Vision May Be Affected Following A Stroke

headache womanAbout 2 in 3 stroke survivors live with some degree of visual dysfunction following the stroke. Although all brains are different and everybody reacts differently, 4 major categories of vision loss can be caused by a stroke.

A stroke can damage any segment of the neural pathway that connects the eyes to the brain or a section of the brain that processes the images the eyes send it. Damage to either area can lead to vision loss.

Stroke-related vision problems can make daily living a challenge, but there is hope for stroke survivors who suffer from visual symptoms.

In honor of World Stroke Awareness Month, we’ll explore 4 types of stroke-related visual problems, and how Associates in Eye Care can help.

1. Visual Field Loss

A stroke can damage certain areas of the brain responsible for either central or peripheral vision, causing a portion of the visual field to be lost, causing vision to be ‘blacked-out’ or have ‘blind spots.’

In most cases, the same area of the visual field is lost in both eyes. This condition is called homonymous visual field loss, meaning a person may not be able to see the right or left side of their visual field from each eye.

Affected individuals may have difficulty with reading and may bump into things located in their blind spots.

2. Visual Processing Difficulties

Sometimes, a person may be able to see everything in their visual field but will have problems processing that visual information. For example, they may have the ability to see another person’s face, but might not recognize it. They may also have difficulty identifying or interacting with common objects, affecting daily tasks such as making a cup of coffee.

Visual neglect is the most common type of visual processing problem. People with this condition aren’t aware that they aren’t seeing people or objects on the right or left side of their visual field.

3. Eye Movement Problems

A stroke can damage the delicate nerves that control the eyes’ movements. A person who cannot control their eye nerves may have difficulty moving their eyes in order to shift their focus from one object to the next or have trouble tracking moving objects.

Nystagmus (involuntary and rapid eye movements) is also a possible complication of ocular nerve damage.

If only one eye is affected, the patient will usually experience double or blurred vision. Whether one or both eyes are affected, poor depth perception can result from eye movement dysfunction.

4. Dry Eye Syndrome

Stroke-related muscle weakness is common, especially in the eyes and face. If this occurs, the eyelids may not be able to fully close during blinking or while asleep. This can lead to dry eye syndrome, causing symptoms like red, itchy, watery, burning eyes and light sensitivity.

Fortunately, many of these post-stroke visual symptoms are treatable with neuro-optometric rehabilitation therapy.

A customized neuro-optometric rehabilitation therapy program can help you return to your normal routine, or at least make daily life less challenging.

If you or a loved one have suffered a stroke, speak with our optometrists about getting your vision evaluated to identify deficiencies in the visual system. If a problem is found, we’ll help guide you through all of your treatment options for the best possible outcome.

Is It Normal To Have Long-Lasting Symptoms After A Head Injury?

man in blue and brown plaid dress shirt touching his hair 897817Perhaps you can relate to one of these scenarios:

After sustaining a mild head injury in a car accident, you now have trouble focusing any time you try to read. You can’t concentrate and feel the need to shut or cover your eyes to find some relief.

Or maybe your child fell and took a blow to the head while playing sports and has complained of headaches ever since. Traditional headache remedies just aren’t effective, and your primary care doctor assures you that no obvious brain damage has occurred and that the headaches will resolve shortly — but they persist.

For the estimated 1.5 million Americans who suffer from traumatic brain injuries (TBI) every year, these scenarios are typical of post-TBI struggles. Concussions and other forms of TBI can seriously impact lives by generating long-lasting symptoms. Fortunately, a neuro-optometrist can provide a crucial component to the healing process with neuro-optometric rehabilitation therapy.

If you or a loved one has suffered even a mild TBI, call Associates in Eye Care to schedule a functional visual evaluation and determine if you can benefit from neuro-optometric rehabilitation therapy.

What Types of Symptoms Follow a Head Injury?

The brain controls much of what goes on in our bodies, so it’s no surprise that a TBI can produce a wide range of symptoms. Below we’ll discuss the most common symptoms and how we can help treat them.

Visual Difficulties

Approximately 90% of all TBIs result in some degree of visual dysfunction. When the eye-brain connection is disrupted, a decrease in visual ability results. Some visual difficulties that may follow a TBI include:

  • Blurred or double vision
  • Photophobia (sensitivity to light)
  • Convergence insufficiency — the inability of the eyes to focus on a near object
  • Binocular vision disorder — eye turn or lazy eye
  • Problems with eye-tracking or eye-teaming
  • Difficulty reading or often losing your place while reading
  • Color contrast issues
  • Peripheral vision defects
  • Eye strain or tired eyes
  • Decreased visual acuity

Headaches and Migraines

In many cases, headaches, including migraines, can be caused by a visual dysfunction. Following a TBI, the ocular muscles will need to exert extra effort to compensate for trauma to the visual system. This additional effort can lead to eye strain.and cause pain in the temples and forehead similar to —and often mistaken for— a tension headache or migraine. Correcting the visual problem will, in many cases, alleviate the intensity and frequency of headaches, or eliminate them entirely.

Dizziness and Balance Problems

The eyes provide the brain with vital information regarding balance and coordination, so when the eye-brain connection is affected you may feel off-balance. This is especially true when a binocular vision disorder is present. Even the slightest misalignment of the eyes can make you feel dizzy, light-headed, or lose balance. Small degrees of misalignment can often be overlooked during routine eye exams, making it all the more important to see a neuro-optometrist in the presence of symptoms.

Concentration

Another possible after-effect of a concussion or other TBI is difficulty concentrating, especially when reading. It may be challenging to keep your place on the page or smoothly navigate along a sentence without having to stop and close your eyes momentarily for relief. Other potential challenges include problems with comprehension, memory difficulties, or trouble with multitasking.

How A Neuro-Optometrist Can Help

Neuro-optometrists are Doctors of Optometry (OD) who’ve been through postgraduate training to assess and treat visual disorders related to TBI and other similar conditions. The goal of neuro-optometric rehabilitation is to retrain the eyes and brain to work in unison and regain clear and comfortable vision by using specific visual exercises. Just as with any other rehabilitation therapy, the earlier one starts the rehabilitation program following a TBI, the higher the chance of recovering lost visual skills.

Dizziness and Balance: How Vision Plays a Vital Role

dizzyImagine trying to navigate a grocery store when, all of a sudden, a dizzy spell hits. The room starts to spin and you lose your balance. You struggle to stand up straight, your vision becomes blurred and orienting yourself in your surroundings becomes insurmountable. To those with vertigo and balance problems, performing simple daily tasks — such as grocery shopping — can feel defeating.

Maintaining proper balance is complex and relies on the collective, healthy functioning of three separate systems: the inner ear, muscle-joint feedback, and vision. Ongoing research suggests that there may be a relationship between a heightened risk of falling and poor vision.

If you experience frequent dizzy spells and difficulty maintaining your balance, make an appointment with [tokensname=’SpDoctorVT’] to rule out any visual dysfunction that could be at the root of the problem.

How Does Vision Affect Balance and Dizziness?

A good sense of balance depends on your ability to see where you are in relation to your surroundings as well as where certain key body parts are in relation to the rest of the body. This information is received by receptors in the muscles and joints but also implicates vision.

The most important visual skill needed to maintain balance is binocular vision, which is the eyes’ ability to work together in creating a clear and unified view of the world around you. The visual system helps regulate the other systems involved in maintaining balance, this means that any defect in the visual system can lead to frequent falls and a balance disorder.

Visual dysfunctions that cause blurred or double vision are common in balance disorders, but can also be its root cause. By improving your vision functionality, you could significantly improve balance and diminish the frequency of dizzy spells.

We Treat Visual Dysfunctions To Improve Balance and Reduce Dizziness

To get to the root of the condition and to assess its connection with vision, our optometrists will evaluate a wide range of visual skills, such as oculomotor skills, eye teaming and tracking, focusing, visual processing, and how well the brain interprets visual information.

If a visual dysfunction is detected, a fully customized neuro-optometric rehabilitation program will be provided to treat the visual components contributing to the balance disorder. With the patient’s participation and diligence, the visual skills and abilities can be improved over time.

What Is Neuro-Optometric Rehabilitation Therapy?

Neuro-optometric rehabilitation therapy, a form of vision therapy, enables those suffering from visual problems to retrain the brain and eyes to regain functionality and quality of life. This therapy uses a variety of methods and techniques to train both eyes to work as a team. It is made up of individualized exercises, which, when done over a period of time rehabilitate visual, perceptual and motor disorders, thus helping the patient regain balance. This effectively reduces or resolves symptoms of dizziness, vertigo, and lack of balance.

The neuro-optometric rehabilitation program offered at Associates in Eye Care can help detect and treat the underlying vision problem causing your dizziness and balance issues.

If you’ve tried other types of therapies and still experience dizziness and balance problems, it’s time to see what our optometrists can do for you. Start your journey to recovery by calling Associates in Eye Care and schedule your appointment today.

Tips to Avoid a Concussion or TBI

close up eye lips 640

The complexity of the brain is truly fascinating; any slight change in its chemistry or structural integrity can result in a multitude of health problems, such as visual disturbances or permanent vision loss. This can affect everyday activities such as driving, walking, reading, using a computer, and staying focused. Below we’ll discuss what traumatic brain injury is and how to avoid one.

What Is a Traumatic Brain Injury?

A Traumatic Brain Injury, or TBI, is an injury to the brain caused by physical trauma, typically a sudden blow or bump to the head.

Concussions — a mild form of brain injury — are very common and makeup 75% of all TBI incidents. A concussion involves a short loss of normal brain function, as the hit can cause the brain to bounce around in rapid motion within the skull, occasionally causing chemical changes or damaging brain cells.

Moderate to severe TBIs cause the victim to lose consciousness from a few minutes to several hours. This can impact cognitive capacity along with other visual symptoms, such as:

  • Difficulty reading and writing
  • Partial or total loss of vision
  • Light sensitivity
  • Double vision
  • Weakened eye muscles

There are numerous ways a TBI can occur, most of which are activities most of us do on a daily basis.

What Causes Traumatic Brain Injury?

Head injuries that cause TBI can happen during everyday activities such as running, hiking, swimming, or competitive sports.

The most common causes of TBIs are:

  • Sports injuries
  • Motor vehicle accidents
  • Falls
  • Being struck by an object

TBIs are more common than one would expect, affecting 10 million individuals around the globe annually. Below we’ll discuss what steps to take in order to prevent a TBI.

Tips for Avoiding Concussion and TBI

ski kidsOne of the best ways to protect against a concussion or TBI is to avoid any risky behavior. While this isn’t always possible, there are some steps you can take to protect your brain and eyes from trauma and damage.

Here are our top four tips:

1) Wear Protective Sports Gear

There are 3.8 million TBIs occurring each year in the US, and 20% are from sports. Wearing protective helmets and eyewear when playing basketball, baseball, or football can help prevent serious injuries, especially in children.

Speak with our optometrists about shatter-resistant polycarbonate or Trivex lenses, known for their impact-resistant materials.

2) Wear Sunglasses

Sun glare can cause momentary blindness. It’s that quick second of feeling blinded by the sun while you’re outside, driving in a car, or at the beach that can make you vulnerable to injury. An easy way to guard against this is by wearing sunglasses.

Sunglasses with polarized lenses prevent glare from entering your eyes by blocking strong light that reflects off surfaces such as glass, water, snow, sand, or pavement. Make sure that the sunglasses you choose contain 100% UV-blocking protection. Photochromic lenses are a smart option for those with prescription eyeglasses, as they darken when outside and revert back to clear lenses when indoors.

3) Pay Attention To Your Surroundings

As obvious as this may sound, people often forget to pay close attention to their surrounding environment. We all know that talking on the phone or texting while driving is dangerous, but being unaware of what’s happening around you can pose certain risks as well. Try to reduce your distractions when walking, driving, or performing any extraneous labor. When outdoors, be on the lookout for sharp objects or debris that can pose a risk.

4) Don’t Forget to Wear Your Seatbelt

Parents and doctors have been drumming it into our heads for years, and for good reason! The #1 way to prevent or reduce car accident injuries is by wearing a seatbelt. According to The United States Centers for Disease Control and Prevention, 2.6 million American drivers and passengers were treated in hospital emergency rooms for car accident-related injuries in 2016. Transport Canada estimates that 25% of car accidents where victims were not wearing seat belts resulted in serious injuries, while 55% were fatal. In fact, car accidents are the number one cause of TBI-related deaths in America, especially among adults aged 20-24.

How a TBI Affects Vision

A TBI can negatively impact your vision, leading to sensitivity to light, blurry or double vision, or persistent eyestrain. In many cases, certain types of activities that were easier before the TBI suddenly become difficult. These include reading a book, driving a car, or watching TV.

Studies show that about 90% of TBI patients suffer from such visual dysfunctions, making it all the more critical to take precautionary measures in staying safe.

If you or a loved one displays any of these symptoms following a TBI, contact Associates in Eye Care right away. our optometrists can offer a neuro-optometric rehabilitation program to help regain any visual skills that were lost. Feel free to call us with any questions you may have – we’re here for you.

Can Neuro-Optometric Rehabilitation Help Stroke Patients With Vision Problems?

senior woman with middle aged woman blog imgIf a loved one recently suffered a stroke and is still struggling with the after-effects, you will want to do everything in your power to help them quickly recover. Unfortunately, it can be painstaking to find the right treatment for their specific needs.

The first thing to keep in mind is this: a single treatment is not going to cure everything. Instead, combining a set of complementary therapies promises optimal results. Read on to find out how neuro-optometric rehabilitation plays an important role in the recovery process from a stroke.

How Does a Stroke Affect Vision

A stroke occurs when the blood flow to the brain (or a section of it) is interrupted. In other types of strokes, a blood vessel in the brain bursts causing major damage in the area. Depending on where in the brain the stroke occurs, it affects different body functions.

Because visual information is processed through the visual cortex of the brain, any brain damage may also affect vision-related processes and quality of vision. Such visual defects are not always obvious and frequently overlooked in initial evaluations following a stroke.

Try to help the stroke victim identify any of the following symptoms:

  • Blurred vision (even over short periods)
  • Sensitivity to light (photophobia)
  • Reduction or loss of visual field
  • Headaches when engaged in visual tasks
  • Reading difficulty
  • Difficulties with eye movements

If any of these symptoms are present, a thorough assessment by a neuro-optometrist is needed.

Why Consult a Neuro-Optometrist?

A regular eye exam by an optometrist checks for eye diseases and visual acuity. A functional eye exam by a neuro-optometrist takes a completely different approach. The goal is to identify neurological vision-related issues and address the types of vision loss caused by a stroke.

About one-third of post-stroke patients experience one or more of these conditions:

  • Loss of visual field – Part of the person’s visual field disappears. In many cases, they will see only the right or the left half of it.
  • Lack of control over eye movements – When the eye nerves are damaged, the eyes may not move as desired or move involuntarily, causing eye turn (strabismus), double vision (diplopia), or other similar issues.
  • Constant, unsteady eye movement (nystagmus) – A continuous fidgety jiggle of the eye, which can move up and down, sideways or in a circle.
  • Visual neglect – When the person is not aware of or does not respond to something he/she sees. There is nothing wrong with the eyes themselves, but the brain does not interpret the images it receives.
  • Agnosia – Often people have trouble recognizing familiar objects and even faces. The cause is similar to visual neglect.

It is easy to see how these affect the overall behavior of a person. At the same time, many may mistake their lack of orientation, bumping into things and/or ignoring people for a problem unrelated to vision.

Choosing the Right Neuro-Optometrist for a Stroke Patient

An exam by qualified professionals will provide clarity into the situation, so make sure to choose an optometry practice that includes a neuro optometrist with extensive training and experience in neuro-optometric rehabilitation such as Associates in Eye Care.

The therapy may include prism lenses to shift images into the visual field or join the images in case of double vision. Exercises to train the brain to manage vision and compensate for vision loss are also part of the therapy.

Your loved one deserves optimal healing, and to ensure this, rehabilitative vision therapy should be part of the overall treatment plan. If he or she is already undergoing physical or occupational therapy, consider adding neuro-optometric rehabilitation for a more holistic approach and better results.

How Successful Is Neuro-Optometric Rehabilitation Therapy?

Vision therapy will help improve the condition of your family member or friend. The speed and extent at which the patient will recover depend on the severity of the condition. Having said that, keep in mind each person is unique and reacts differently to the same treatment.

Neuro-optometric rehabilitation therapy is not a cure, but it will enhance visual skills and quality of life for the person you care for.

When vision is dysfunctional, so is everything else. Getting one’s vision back on track can greatly enhance daily function and quality of life. Help your loved one get his/her life back, contact Associates in Eye Care today.

This can lead to severe health problems because unlike other physical injuries, a TBI affects the brain which controls, well, pretty much everything else in the body.

Traumatic Brain Injuries occur more frequently than is generally assumed. In fact, there are a number of myths and misconceptions about TBIs, which is why we wrote up 5 things about this condition that you probably didn’t know:

1. A Concussion Does Not Automatically Lead to Unconsciousness

A mild form of TBI is known as a concussion. TV and movies frequently give the impression that people pass out when concussed, but these reactions are dramatized and not quite realistic. Most people who suffer concussions remain awake and aware of their surroundings, despite being less alert than usual. Only around 10% of concussion incidents result in a loss of consciousness.

2. In the United States, A TBI Occurs Every 9 Seconds!

An estimated 1.7 million Americans suffer from traumatic brain injury every year, and of those, about 75% of the cases are mild brain injuries or concussions. In Canada, the rates are equally alarming with 452 Canadians incurring severe brain injuries on a daily basis – excluding concussions. Not surprisingly, TBIs are often referred to as a silent epidemic.

3. Falls Are the Most Common Cause of TBI’s

According to the U.S. Center for Disease Control, falling is the number one cause of TBIs. The second most common cause is being hit in the head with an object or a car accident. Among children and teens, a whopping 21% of TBIs occur during sports, such as running, hiking, biking, swimming, skating.

4. Women Are at Higher Risk for TBI’s Than Men

Though experts don’t know why gender seems to play a role, women experience a higher risk of incurring a TBI than men. Studies have tried to determine the reason behind these statistics, and while it still remains unclear, the hormones in the brain are thought to contribute on some level.

5. 90% of TBI Cases Result in Some Form of Visual Impairment

According to the Neuro-Optometric Rehabilitation Association, 90% of TBI patients experience visual problems associated with their concussion. The most common visual disturbances include:

  • Blurred or double vision
  • Photophobia (light sensitivity)
  • Headaches due to eye strain
  • Difficulty reading
  • Loss of peripheral vision
  • Eye movement complications

Keep in mind that vision problems may not be immediately noticeable following the trauma. It may take weeks for certain visual aberrations to manifest, which is why it’s imperative to schedule an eye exam at Associates in Eye Care as soon as possible.

If you or a loved one displays any of these symptoms following a TBI, speak with our optometrists regarding the neuro-optometric rehabilitation program. This rehabilitation program is a safe, practical, and effective method used to help patients regain visual skills adversely impacted by brain injury.

our optometrists provides treatment for TBI patients from Somerset, Russell Springs, Jacksboro, Jellico, and throughout Southern Kentucky and North Tennessee.
