Can Restricting Online Gaming Time Reduce Myopia Progression?

Two kids playing online gamesThe Chinese government recently implemented a new policy that’s sparked conversations about childhood myopia and online gaming.

Under the policy, Chinese children and teens under the age of 18 are only permitted to play online video games for one hour on weekend evenings and public holidays — a significant reduction compared to their previous online gaming allotment. This restriction includes all forms of video games, from handheld devices to computer and smartphone gaming.

The government hopes to combat a common condition called online gaming disorder, or video game addiction, which affects more than 30% of children in China. Another potential benefit of limiting online gaming may be a reduction in childhood myopia progression, something we explore below.

The Link Between Online Gaming and Myopia Progression

Myopia, or nearsightedness, is a condition that causes blurred distance vision. Several factors contribute to the onset and progression of myopia, including genetic and environmental.

Several studies have found that screen time, along with other forms of near work, is associated with higher levels of myopia and myopia progression in children.

According to a study published in the British Journal of Ophthalmology (2019), children who engage in screen time for more than 3 hours per day have almost 4 times the risk of becoming myopic. Younger children, around ages 6-7, are even more susceptible to experiencing screen-related nearsightedness, with 5 times the risk compared to children who don’t use digital screens.

Limiting screen time may also encourage children to spend more time outdoors in the sun, a protective factor against developing myopia and slowing its progression.

In The Sydney Adolescent Vascular and Eye Study (2013), researchers found that spending at least 21 hours outdoors per week was more important for delaying the onset of myopia than limiting near work in both younger and older children, although both were effective.

What’s the Bottom Line?

Although online gaming can give children a sense of community and togetherness, excessive online gaming can increase a child’s risk of developing myopia and contribute to its progression.

The good news is that parents can make eye-healthy choices for their children that can have lifelong benefits. Limiting near work activities like online gaming and other screen time, and encouraging your children to play outdoors can significantly reduce their chances of developing high (severe) myopia.

How Myopia Management Can Help

How Sports Vision Training Can Improve a Quarterback’s Game

How Sports Vision Training Can Improve a Quarterbacks Game 640×350Quarterbacks (QBs) work hard to increase their physical strength but often don’t realize that improving their visual skills can also improve their effectiveness on the field.

In addition to having a powerful throwing arm, quarterbacks must be able to precisely judge distances and the speeds of other players. They need to be aware of everyone and everything around them, as well as every player’s specific location and course of movement — all while following the ball.

Visual skills like accurate peripheral vision and split-second reaction time are crucial to a quarterback’s success. Sports vision training provides the foundation for these abilities and allows players to be the best athletes they can be.

Contact Chula Lerdvoratavee, OD to see how sports vision training can help you improve your game.

Which Visual Skills Can Sports Vision Training Improve?

Here are examples of how a quarterback depends on visual skills.

Eye Focusing

QBs need to be able to sustain sharp focus and to shift their eyes and focus rapidly and precisely to judge the exact position of the tight end as the linebackers close the space.

Depth Perception

The quarterback’s ability to accurately judge the position of his receivers sprinting full speed into the end zone depends on sharp and precise depth perception.

Peripheral Vision

All eyes are on the quarterback in possession of the ball, but it’s just as important for the quarterback to keep track of the defensive players as they attempt a sack. QBs with good peripheral vision can see where all the defenders are at any given time.

Visual Reaction Time

Visual reaction time is the speed with which a quarterback’s brain analyzes and reacts to the opponent’s actions. A QB’s next move will be determined by how quickly and well their brain integrates visual and motor functions.

Gross-Visual Motor Integration

While on the move, a quarterback needs to analyze all of the information the eyes are transmitting, and act on it quickly. This requires a high level of coordination between the QB’s brain, eyes and body. The more the quarterback’s vision and movement are synchronized, the more successful the plays will be.

All of this takes a matter of seconds. With good visual skills, a quarterback can make that play seem flawless.

Enhancing the Performance of a Quarterback

We offer sports vision training to help all kinds of athletes achieve their goals and take their game to the next level. A functional eye exam will evaluate visual skills, after which we can create a personalized sports vision training program.

At The Scott Eye Care Sports Vision Center, we help players be the athletes they know they can be. We offer sports vision training to patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: What is sports vision training?

  • A: Sports vision training is a custom-made program that improves coordination between your brain, eyes and body while playing sports. Through a series of eye exercises and techniques, it helps athletes react faster and more accurately to what they see on the field.

Q: Who can benefit from sports vision training?

  • A: Whether you’re a quarterback or a linebacker, an avid baseball or hockey player, sports vision training is perfect for athletes of any age and ability seeking to improve their sports performance.

What’s a Multifocal Intraocular Lens?

Multifocal Intraocular Lenses 640×350A cataract clouds the eye’s natural lens, leading to significant visual distortions that can affect your ability to see clearly. Eventually, the natural lens will need to be removed and replaced with an artificial intraocular lens (IOL) that provides clear vision.

While most patients pick monofocal IOLs, many patients choose multifocal IOL lenses. Discuss with your [eye_ doctor] which type of IOL is right for you.

What Is a Multifocal Intraocular Lens?

A multifocal IOL allows patients to see all distances clearly. These IOLs allocate different optical powers on the IOL. The varying optical powers are created by the IOL design, which incorporates concentric rings on the surface of the lens. These allow images at a variety of distances to be in sharp focus.

It can take some time for people to adapt to multifocal IOL lenses because the focusing power the lenses provide is different from what people are accustomed to. Since the IOL relies on a different design than the bifocal or multifocal optical lenses used in eyeglasses, the brain might need time to adjust.

To ease the adjustment, most cataract surgeons recommend having multifocal IOLs implanted in both eyes, rather than just one.

Are Multifocal IOLs Right for You?

If you are looking for an IOL that can provide you with clear vision for reading, driving and watching TV, a multifocal IOL may be just right for you.

After cataract surgery, multifocal IOLs can reduce the need for reading glasses or computer glasses. These implanted lenses widen your field of vision, allowing you to see well both up close and far, often without the use of glasses. Many patients who choose multifocal IOLs find that they can go glasses-free or only occasionally need reading glasses for small print after surgery.

Despite the obvious benefits of these lenses, they may not be suitable for everyone. Some patients find that it takes longer to adapt to multifocal lenses than to monofocal lenses. Contact to discover whether IOL multifocal lenses are right for you.

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: How does a multifocal IOL work?

  • A: When wearing bifocal or multifocal glasses, you look through the bottom part of the lens for near vision and through the top part of the lens for distance vision. A multifocal IOL is specially designed to provide clear vision at all distances at all times. Your brain adjusts, allowing you to see clearly for the task at hand.

Q: Will a multifocal IOL eliminate the need for glasses?

  • A: Most people find they do not need glasses with multifocal IOLs, but some do, depending on the situation. There may be times when the print or graphics are simply too small or too far away to be seen without glasses.

Screen Time Can Lead To Eye Strain And Convergence Insufficiency In Children

Screen Time 640×350Now that a couple of years have passed since the start of the COVID-19 pandemic, researchers have gotten a clearer picture of the impact that online schooling has had on children’s eyes.

Not only have myopia cases increased, but more children are experiencing symptoms of eye strain and convergence insufficiency due to extended screen time.

Below, we explore what eye strain and convergence insufficiency are, and how vision therapy can help counteract the negative effects of online learning.

Symptoms of Digital Eye Strain

Prolonged use of digital devices like computers or smartphones can cause a condition called computer vision syndrome, also known as digital eye strain. This condition affects around 50% of adults and children.

Symptoms of digital eye strain include:

  • Sore eyes
  • Blurred vision
  • Neck and shoulder pain
  • Headaches

Children who complain of any of these symptoms should have their eyes evaluated by a developmental optometrist to ensure that vision problems aren’t exacerbating their symptoms.

What is Convergence Insufficiency?

Normally, when your eyes focus on a very near object, like a pencil near your nose, they must point slightly inwards to see a unified and clear image.

With convergence insufficiency, the eyes aren’t able to work in unison to point inward. Instead, one eye may point outward when trying to focus on a near object, leading to blurred or double vision.

Children with convergence insufficiency may struggle to perform visually demanding near tasks like reading and homework. In fact, many children who have vision-related learning problems are often misdiagnosed as having learning disabilities.

How Does Screen Time Lead to Eye Strain and Convergence Insufficiency?

Experts at Wills Eye Hospital recently studied the correlation between prolonged screen time and its effects on children’s eyes. They surveyed 110 students aged 10-17 who attended classes online. Prior to the beginning of online sessions, the students all had healthy vision.

The researchers discovered that the number of hours spent in front of a screen directly correlated to the likelihood of developing digital eye strain and convergence insufficiency. More than half of the students experienced symptoms of both visual conditions, with 17% of cases being severe convergence insufficiency.

These important and timely findings should alert parents to the risks that come with online learning, and encourage them to find solutions and take preventative measures to keep their kids’ eyes healthy. Fortunately, that’s where vision therapy comes in.

How Can Vision Therapy Help?

Vision therapy trains the eyes and brain to work together efficiently to resolve a wide range of visual dysfunctions.

Restoring healthy binocular vision is the goal for children with convergence insufficiency, and vision therapy is a primary treatment for accomplishing that.

According to the National Eye Institute, most children with convergence insufficiency experience significant improvement after just 12 weeks of vision therapy.

Vision therapy can also be effective for treating symptoms of digital eye strain in children. According to the Optometrists Network, a free and extensive online library for eye care, vision therapy can relieve symptoms of digital eye strain by strengthening the visual system.

To learn more about the benefits of vision therapy or to schedule your child’s functional visual evaluation, contact Developmental Vision Center today!

Developmental Vision Center offers vision therapy to patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: What is a functional vision evaluation?

  • A: A functional visual evaluation assesses a multitude of visual skills that normally aren’t tested in standard eye exams or vision screenings. Some examples of those visual skills include convergence, eye tracking and teaming, visual processing, eye movement, focusing, eye alignment and accommodation flexibility.

Q: Who is a candidate for vision therapy?

  • A: Children and adults who have varying degrees of visual dysfunction are ideal candidates for vision therapy. Many patients may not be aware of problems with their visual systems but suffer from symptoms like headaches or dizziness, which may be rooted in their vision. Children with learning problems or any visual symptoms may benefit from a customized vision therapy program.

What’s the Difference Between Low Vision and Blindness?

Whats the Difference Between Low Vision and Being Legally Blind 640×350

Low vision doesn’t mean blindness. It simply means that a portion of your vision is impaired, and you can continue to enjoy a high degree of independence thanks to low vision tools and devices.

What Is Low Vision?

People often confuse the terms ‘visual impairment,’ ‘low vision,’ or ‘blindness’. Below we’ll untangle that and bring some clarity to each term:

Visual impairment is a broad term that refers to any loss of vision. The following are some of the terms used to characterize different types of vision impairment:

  • Low vision is defined as fully corrected vision that is insufficient or interferes with your ability to do the things you want to be able to do. It has nothing to do with your visual acuity, field of view or other visual functions like dark adaptation or contrast sensitivity.
  • Legally blind refers to vision that is 20/200 or less in your better eye that cannot be corrected with standard glasses or contacts, or a visual field of 20 degrees or less. Certain conditions, like glaucoma, cataracts, diabetic retinopathy, and macular degeneration can cause one to be legally blind.
  • Total blindness is defined as the complete lack of form and light perception that often results due to a genetic condition, disease, or injury.
  • Partial vision refers to the capacity to see only a portion of your visual field, or to have good central vision but poor peripheral vision. A brain tumor, brain injury, or an eye condition are the most common causes.

Does Low Vision Mean Blindness?

No. Vision loss that cannot be corrected with glasses, contact lenses or surgery is known as low vision. However, because some vision remains, it is not considered to be blindness. A person with low vision may have blurred vision, blind spots or have poor night vision.

Common Types of Low Vision

Loss of central vision

A blur or blind spot in the center of what you’re looking at occurs from a loss of central vision. This makes it difficult to read, recognize people and identify features at a distance. A person’s side (peripheral) vision is mostly unaffected by the loss of central vision.

As long as the person has adequate side vision, mobility is still possible.

Loss of peripheral (side) vision

Peripheral vision loss leaves a person with remaining central vision, allowing them to see straight ahead, read, watch TV and recognize faces. This is referred to as tunnel vision and can be caused by glaucoma, a brain tumor or injury.

Peripheral vision loss makes it difficult to differentiate objects on one or both sides, as well as items directly above and below eye level. Mobility is often hindered by a loss of peripheral vision.

Blurred vision

Blurred vision causes both near and far vision to be out of focus. When blurred vision is caused by refractive error, glasses, contact lenses and sometimes surgery can clear it up. However, certain conditions may cause blurred vision that cannot be corrected, such as macular degeneration, cataracts and diabetic edema.

Reduced contrast sensitivity

People with poor contrast sensitivity struggle to distinguish an object from other objects having the same background color/shade. For example, a person wearing gray clothing would be difficult to see on a cloudy day. Similarly, finding a blue wallet in a blue purse can be difficult for those with reduced contrast sensitivity. Others may find driving difficult even if their “acuity” is good because visual acuity is measured on high contrast charts. The most common eye diseases that cause contrast sensitivity loss include macular degeneration and cataracts.

Glare/light sensitivity

There are two types of glare: discomfort glare and disability glare.

Patients with discomfort glare tend to feel discomfort in the presence of sunlight, incandescent lights, fluorescent lights, and halogen lights, like those used in car headlights. Glare can emanate from many sources, such as reflection from water, fresh snow or white sand.

Those with disability glare cannot function in these lighting conditions, posing a danger of being in harm’s way.

Both types of glare can be helped by a Low Vision of Fox Valley low vision eye doctor.

Night blindness

People with night blindness find it difficult to see outside at night or in dimly lit indoor settings.

How Low Vision Devices Can Help

People with low vision can often live and work independently thanks to a number of tools and devices that can greatly improve their quality of life.

Our low vision optometrist prescribes all types of low vision glasses and devices, such as:

  • bioptic and full diameter telescope glasses
  • microscope glasses
  • prism glasses
  • and filters of all types
  • as well as a wide range of low vision aids ranging from hand-held magnifiers to electronic visual aids.

Large-type books, magazines, and newspapers, as well as books on tape, talking wristwatches, self-threading needles and other products can also help those with low vision.

Live your best life by contacting Low Vision of Fox Valley to book a low vision evaluation and to determine the optimal low vision devices for your needs and lifestyle.

 

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: What is a low vision evaluation?

  • A: A low vision evaluation includes components that are not usually part of a standard eye exam. Your vision will be evaluated to assess the nature and level of vision loss and how it’s affecting your ability to do the things you want to do. The evaluation will help determine which types of low vision glasses and devices to prescribe for improved function, safety and independence.

Q: What causes low vision?

  • A: Traumatic brain and eye injuries, as well as congenital conditions and issues of aging and uncorrected refractive errors, are all common causes of low vision. As you age, you’re more likely to develop various eye conditions, like cataracts, glaucoma, diabetes and age-related macular degeneration. When treated early, vision loss can be prevented or limited. However, left untreated, some of these conditions can eventually lead to severe vision loss or even total blindness.

Low Vision of Fox Valley provides low vision management, aids and devices to patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

Blinking Exercises for Dry Eye

Blinking Exercises 640×350Did you know that the average person spends around 7 hours a day looking at a screen? The glare and reflections from computer, smartphone, and tablet screens can reduce blink rates by as much as 60%. When we concentrate intensely we tend to blink less, which can, in turn, lead to dry eye syndrome.

Symptoms of dry eye syndrome include red and dry eyes, irritated eyes, blurred vision, painful or stinging eyes, light sensitivity and mucus around the eyes.

Blinking helps keep our eyes healthy and comfortable. With every blink, the ocular surface is cleaned of debris and lubricated, so less blinking means more irritation and dryness.

Below are a few blinking exercises to help you ensure that your eyes remain lubricated and refreshed throughout the day.

Blinking Exercises

Blinking exercises are simple to do and can be seamlessly integrated into your daily routine. These exercises should be done a few times an hour. Try alternating between the 2 exercises below.

1. Close-Pause-Pause-Open-Relax

  1. Without squeezing, gently close your eyes.
  2. Pause and keep your eyes closed for 2 seconds.
  3. Gently open your eyes and relax them.
  4. Repeat 5 times

2. Close-Pause-Pause-Squeeze-Open-Relax

  1. Without squeezing, gently close your eyes.
  2. Pause and keep your eyes closed for 2 seconds.
  3. While keeping your eyes closed, squeeze your eyelids together slowly and gently.
  4. Gently open your eyes and relax them.
  5. Repeat 5 times

The Importance of Fully Blinking

It’s important to fully blink to completely lubricate your eyes. If you’re only partially blinking, it can render your dry eye symptoms worse.

To find out whether you are fully blinking, just look at your eyes in the mirror. If they feel dry or appear red, or if you see a horizontal stripe of red blood vessels across your eyes, then you have been partially blinking.

If you’ve incorporated blinking exercises into your routine but are still experiencing eye irritation, you may have dry eye syndrome. We can diagnose the underlying cause of your symptoms, and offer a variety of dry eye treatments to alleviate any discomfort. Schedule an eye exam with The Scott Eye Care Dry Eye Center today to receive effective, long-lasting relief.

The Scott Eye Care Dry Eye Center serves dry eye patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: What is dry eye syndrome?

  • A: Dry eye syndrome is caused either by insufficient tears or poor tear quality. Every time you blink, you leave a thin film of tears over the surface of your eyes. This helps keep your vision clear and your eyes healthy. If your tears don’t keep the surface of your eye moist enough, you will experience dry eye symptoms. Some medical conditions, certain medications, dysfunctional glands, allergies and environmental irritants can all cause dry eye symptoms.

Q: What are the symptoms of dry eyes?

  • A: Symptoms of dry eye include irritation; a gritty, scratchy or burning sensation; blurred vision; excessive tearing; and/or a feeling of having something stuck in the eye.

6 Tips For Adjusting To Wearing Scleral Lenses

6 Tips For Adjusting To Wearing Scleral Lenses 640×350Congratulations on your new pair of customized scleral contact lenses! As with most new things, there can be a learning curve when getting your scleral contacts to feel and fit just right.

Whether you’ve been prescribed sclerals for keratoconus, dry eye syndrome, corneal abnormalities or other conditions, it can take up to two weeks for you to feel completely comfortable in your new contacts.

Here are some tips to help shorten the adjustment period on your scleral lens journey:

1. Stick to proper hygiene protocol

Even the most perfectly fitted scleral lenses won’t feel right if they aren’t cleaned and cared for properly. Carefully follow the hygiene guidelines prescribed by your optometrist without cutting any corners. Although it may seem tedious at first, your efforts will be well worth the results.

2. Practice makes progress

The only way to make inserting and removing your lenses second nature is to wear them. Don’t be discouraged if it takes a bit more time to insert them than you’d anticipated. Wearing your sclerals daily will give you the opportunity to practice wearing and caring for your lenses.

3. Try out different insertion tools and techniques

At your initial fitting or follow-up consultation, your eye doctor will show you ways to safely and comfortably insert your lenses. Some patients prefer using a large plunger, while others prefer the scleral ring or O-ring. If neither of these recommended techniques are working for you, seek advice from your eye doctor.

4. Overfill the lens

A common problem that many patients encounter when they begin wearing scleral contact lenses is how to get rid of tiny air bubbles that get trapped in the lens’ bowl. Try filling up the lens with the recommended solution until it is almost overflowing. That way, you’ll have enough fluid left in the lens even if some spills out when you bring it up to your eye.

5. Give it time

If your scleral lenses feel slightly uncomfortable upon insertion — don’t worry. It’s recommended to wait 20-30 minutes to allow them to settle on the eye’s surface before attempting to readjust or remove them. Of course, remove them immediately and try again if you feel significant discomfort.

6. Follow up with your optometrist

Even once you leave your optometrist’s office, we encourage you to remain in touch with your eye doctor if something doesn’t feel right or if you have any questions regarding your scleral lenses.

To learn more or to schedule a scleral lens consultation, call Specialty Contact Lens Center at Scott Eye Care today!

Specialty Contact Lens Center at Scott Eye Care provides scleral lenses to patients from Oswego, Naperville, Aurora, and Chicago, Illinois and surrounding communities.

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

Q: What are scleral contact lenses?

  • A: Scleral contact lenses are rigid gas permeable lenses with a uniquely large diameter. They rest on the sclera (whites of the eyes) instead of the cornea, making them a more comfortable and stable option for people with corneal irregularities or dry eye syndrome. Scleral contacts hold a reservoir of nourishing fluid between the eye’s surface and the inside of the lens, providing the patient with crisp and comfortable vision.

Q: Who is an ideal candidate for wearing sclerals?

  • A: Patients with keratoconus, corneal abnormalities, ocular surface disease (dry eye syndrome) and very high refractive errors can all benefit from scleral lenses. Moreover, those with delicate corneas due to disease or after surgery find scleral lenses to be comfortable and therapeutic, as the lenses don’t place any pressure on the sensitive corneal tissue.

Long-Term Risks of Repeated Head Impacts Among Athletes

Long Term Risks of Repeated Head Impacts Among Athletes 640×350If 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 Developmental Vision Center, 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 Developmental Vision Center today.

Developmental Vision Center offers neuro-optometric rehabilitation therapy to patients from Oswego, Naperville, Aurora and Chicago, Illinois and surrounding communities.

Frequently Asked Questions with Ronald Weingart, OD, Vasana Lerdvoratavee, OD and Chula Lerdvoratavee, OD

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.

What Causes Retinal Tears?

What Causes Retinal Tears 640×350The retina is the light-sensitive tissue that lines the inner back portion of the eye. It is responsible for gathering incoming light and sending images to the brain so they can be processed.

Retinal tears occur when the delicate tissue gets pulled, creating a hole or tear in the retina. They need to be taken seriously because they can lead to a more severe condition called retinal detachment, which is considered a sight-threatening medical emergency.

What are the Symptoms of Retinal Tears?

Patients with retinal tears will often experience one or more of the following symptoms:

  • Flashes of light
  • Sudden onset or increase of floaters
  • Seeing a shadow in your side vision
  • Blurred vision
  • Seeing a gray curtain moving across your visual field

However, in some cases, retinal tears may not produce any noticeable symptoms.

What Conditions Can Cause Retinal Tears?

The eye is filled with a substance called vitreous. At birth, the vitreous is attached to the retina and has a gel consistency. As we age, the vitreous becomes more like a liquid and slowly detaches from the retina in a process called posterior vitreous detachment (PVD).

Usually, this process occurs without any complications. If the vitreous detaches too suddenly or abnormally, it tugs on the retina and can tear it. Additionally, some people have a more “sticky” vitreous, which makes it easier for the retina to rip.

Another main cause of retinal tears is eye trauma. Blunt force eye trauma can cause the retina to become bruised or scarred, making it more vulnerable to tearing.

Other associated causes or risk factors of retinal tears include:

  • Diabetes
  • Personal or family history of retinal tears/detachment
  • Retinal degeneration
  • Inflammatory disorders
  • Certain cancers
  • Autoimmune diseases
  • High myopia
  • Sickle cell disease
  • Retinopathy of prematurity
  • Prior surgery within the eye

Be sure to disclose any relevant medical information to your eye doctor for optimal preventative eye care.

How are Retinal Tears Treated?

Retinal tears are typically treated surgically with a laser (photocoagulation) or cryotherapy. Both methods are considered very safe and effective.

These treatments reseal the retina to the back wall of the eye and prevent fluid leakage underneath the retina.

The prognosis of a retinal tear is very positive when caught early, making regular eye exams that include examination of the retina crucial for all adults.

In some cases of minor retinal tearing, no treatment is required. If the retinal tear causes no symptoms, close monitoring may be all that’s needed.

After Your Retinal Tear Has Been Treated

After treatment, your optometrist will schedule various eye exams in order to monitor any changes in your retinas or eye health. Inform your eye doctor immediately if you notice any changes in your vision or if you experience new symptoms that may signal a problem.

If you or a loved one has been diagnosed with a retinal tear or is at risk of developing one, call to schedule a consultation.

4 Reasons Why Your Child May Be Refusing to Read

4 Reasons Why Your Child May Be Refusing to Read 640×350Reading involves the simultaneous coordination of a number of basic visual skills. For children who have not yet mastered some of these skills, reading can be an exercise in frustration, leading them to avoid reading altogether.

While many of us take our eyes’ ability to converge, focus and track for granted, those with underdeveloped visual skills often struggle to keep track of where they are on the page and to fully understand and remember what they’ve just read.

We’ve outlined four of the top vision-related reasons why children refuse to read, and how vision therapy can help your child become a more confident reader.

1. Eye Tracking Problems

Eye tracking is the eyes’ ability to move smoothly and accurately from place to place. Good eye tracking skills allow a child to keep their eyes on an incoming baseball or move successfully from word to word on a page of text without losing their place.

For a child with eye-tracking issues, eye movements will be slow and inaccurate, often seen as eye flickering or requiring extra head movements, to compensate for the reduced visual skill.

Poor eye tracking can cause a child to frequently lose their spot and skip words or even whole lines of text while reading. In this case, the child uses a lot more energy than their peers to simply keep track of where they are on the page, causing difficulty with reading comprehension and fluency.

2. Difficulties With Eye Teaming

Eye teaming is the eyes’ ability to work together to send accurate visual information to the brain. Although each eye sends a slightly different image, the brain is able to combine these two images into a single picture, allowing for three-dimensional vision and depth perception.

When children have problems with eye teaming, their eyes are unable to work together. They send two very distinct images to the brain, which struggles to easily combine the two images into a single clear, cohesive image.

A child attempting to read with eye teaming issues may experience eye strain, headaches or even double vision. Often, words on a page will look blurry or appear to ‘float’ on the page. Eye teaming difficulties may also cause the child to have a reduced attention span, and lead them to avoid reading or not read at grade level.

3. [Visualization] Problems

Visualization refers to the ability to see something in the mind’s eye even if that thing is not right there in front of us. This skill allows a child to recall words and remember how to spell words that they’ve previously seen. [Visualization] allows many of us to read a story and then ‘see’ the characters and events play through our mind as if we are watching a film.

For some children, however, this doesn’t happen. The brain has a hard time taking the visual information it’s receiving from the eyes and interpreting it into larger images and concepts. This can result in poor reading comprehension and may render that reading is a chore and an unenjoyable experience.

4. Issues with Accommodation

Accommodation is the ability to refocus the eyes each time we shift our gaze from one image or object to the next. This happens as a result of the swift and accurate contraction and relaxation of muscles in the eye to quickly focus and refocus as the eye moves.

In children with accommodation problems, the focusing muscles in the eyes do not smoothly contract and relax efficiently as their eyes move across the page from word to word or from a book (or screen) to the board and back. They need to stop and refocus their vision every time they read another word. This stop-and-start type of reading harms reading comprehension, and the constant need to refocus can cause headaches and eye strain.

So What’s The Solution?

All of the problems mentioned above are due to reduced visual skills and can be frustrating for children and parents alike. Fortunately, there is a solution: vision therapy.

Vision therapy is a personalized, doctor-prescribed evidence-based regimen of in-office and at-home eye exercises to teach your child’s eyes and brain to more effectively work together. Depending on your child’s needs, the customized program may include vision therapy aids such as prism glasses, devices and specialized therapy computer programs.
