Focusing In On Binocular Vision Dysfunction Symptoms

Do you experience dizziness, headaches, sensitivity to light, motion sickness, or even have anxiety in large spaces? These disabling symptoms might be related to Binocular Vision Dysfunction (BVD). A standard comprehensive eye exam might not be enough to catch it. If you have experienced any of the symptoms listed below, it’s important to contact your eye doctor, who will determine the cause and provide you with a treatment plan.

Symptoms Associated With Dizziness, Nausea, Motion Sickness and Lightheadedness

When your eyes correct a misalignment, your eye muscles strain. This strain often leads to an array of symptoms, including headaches, dizziness, and disorientation, as well as feelings of lightheadedness.

BVD can also cause nausea, especially while riding in a vehicle, and balance problems. People with BVD may slowly drift to one side while walking, feel their footing is unsure, and walk into objects. Specialized prismatic visual orthotics can relieve these symptoms, usually quickly.

Reading and Learning Disability Symptoms

Your learning and reading can be affected by having misaligned eyes. BVD may affect up to 50% of children diagnosed with reading and other learning problems. That’s why it’s crucial to test for even small amounts of misalignment. Binocular vision disorders can cause eye fatigue while reading, make it hard for you to concentrate, cause words to blend together, and make you lose your place or skip lines while you read. As a routine eye exam can miss even the smallest of alignments, a neuro visual evaluation can detect very small and subtle misalignments.

Head, Neck, and Shoulder Symptoms

Often, patients with BVD experience headaches where they feel an intense pressure at the crown of their head. If you have BVD as a result of Post Concussion Syndrome you will most likely encounter these frequent, intense headaches. Other symptoms of binocular vision dysfunction found in the head, shoulders, and neck include pain in the sinus area or jaw. Severe neck and shoulder pain are often due to a head tilt caused by the misalignment.

Other Symptoms Of BVD

Other symptoms of a binocular vision disorder that you may encounter include:

  • Double vision
  • Difficulty concentrating
  • Having a hard time making eye contact
  • Eye strain, which can affect sleep patterns

If you or your child are experiencing any of these symptoms and are not sure if it stems from BVD, contact Dr. Jennifer Catalasan in Austin to schedule a neuro visual eye evaluation. To learn more about BVD and what you can do to get relief, contact us today!

Eye Floaters & Flashes: When Are They a Problem?


Micro-Prism Lenses May Be The Answer

Young Boy Concentrating

Headaches, dizziness, off-balance? Your symptoms are not in your head, but they may be in your eyes!

You or your child don’t feel 100%, and so you book a physical exam at your family’s primary physician. The list of symptoms is very long, with many common and sometimes vague sensations, such as headaches, nausea, lack of coordination, dizziness, anxiety, and light sensitivity. When a check-up reveals no serious health problems, your family doctor may send you and your kid home with orders to simply rest up and de-stress. But when taking it easy doesn’t help – how can you find relief?


Schedule an eye exam with our Austin eye doctor! Your symptoms could all be caused by Binocular Vision Dysfunction (BVD), a complex condition where one eye sees an image that’s not aligned with the other eye. In order to correct this misalignment, your body strains your eye muscles. Over time, this overuse of the eye muscles leads to BVD.

Binocular vision dysfunction is common

BVD affects at least 10% of all adults and is often the culprit for chronic headaches and dizziness, but it also often goes undiagnosed. One reason is because basic vision testing (which is what many people do each year) just checks each eye for its visual acuity. Only a comprehensive eye exam done by a qualified eye doctor will assess how your eyes work together – called binocular vision. Even the tiniest amount of misalignment can cause the disturbing symptoms of BVD.

Micro-prism lenses can bring relief

Micro-prism lenses are specialized lenses that work to realign the images sent to your eyes, instead of requiring your eye muscles to strain in order to realign what you see. At our Austin eye care center, we’ve treated many patients with binocular vision dysfunction with micro-prism lenses – and witnessed a significant reduction in their symptoms. Many people who struggled for years were thrilled to finally feel better! They reported a new ability to focus at work and excel on the sports field, as well as less anxiety or fewer panic attacks.

BVD affects kids too

Children who suffer from binocular vision dysfunction often complain about travel sickness and how light bothers their eyes. In school, they may tend to tilt their head to one side while reading, and skipping lines is a classic symptom. Once our Austin optometrist fits these children with micro-prism lenses, many of these kids immediately find it easier to concentrate in school, and their grades go up.  The trick is to bring kids to an eye doctor as soon as the symptoms are noticed, because living with BVD in school can seriously compromise learning, leading to poor self-esteem and a bunch of behavioral problems.

Get an edge on your sports game with micro-prism lenses

What’s your game? Soccer, tennis, golf, gymnastics, basketball? No matter what you play, sharp hand-eye coordination and accurate 3D depth perception are essentials of excellence in almost every sport. If you can’t figure out exactly where the ball is and track where it’s going, your game will suffer. BVD gets in the way of throwing and catching any type of ball!

Even if your eyes are only out of alignment a bit, your 3D stereo vision won’t work right. Micro-prism lenses can be the solution. Once these lenses are incorporated into your sports glasses or goggles, they will help to align your eyes. As a result, your depth perception will be restored and optimized.

Concussion? Micro-prism lenses can help

Recent studies (published in Physical Medicine and Rehabilitation), have shown that brain injury can lead to BVD, and specialized glasses with micro-prism lenses can be very effective at alleviating traumatic brain injury symptoms. Doctors have always known that concussions can cause vision problems, but now the link between these symptoms (e.g. headaches, dizziness, neck pain, anxiety) and vision has been clarified.


It appears that traumatic brain injury actually causes vertical heterophoria, which is a binocular vision dysfunction. With vertical heterophoria, your line of sight from one eye is higher than from the other eye. By wearing micro-prism lenses, the images are realigned and your eye muscles don’t have to overwork to line up what you see. With treatment by micro-prism lenses, many post-concussive patients experienced total relief – allowing them to reduce or eliminate many prescribed medications.

Look to your Austin eye doctor for relief! Micro-prism lenses may be the answer

The frustration of going from doctor to doctor to seek relief from your disturbing symptoms can be enormous! Stop looking in the wrong place and book an appointment with our Austin for a comprehensive eye exam. You may have binocular vision dysfunction, and we can fit you with customized micro-prism lenses to realign your focus and restore your quality of life!



Headaches, Dizziness, Motion Sickness? It Could Be Vertical heterophoria

Diagnosis and treatment for this binocular vision dysfunction in Cedar Park, TX

Vertical heterophoria (VH) is a type of binocular vision dysfunction (BVD) caused by a misalignment of your eyes. And it can result from even a very slight misalignment that isn’t immediately noticeable to you or to people looking at you. Basically, when you look at the world through misaligned eyes, your muscles take corrective measures to help you see clearly and in focus. This automatic reaction strains your eye muscles and leads to a slew of uncomfortable symptoms, including headaches and dizziness.

Symptoms of vertical heterophoria

blurry visionThe symptoms of VH may not be constant and can be intermittent throughout your day. In fact, you may feel perfectly fine one minute, only to feel a minute later like you just got off a thrilling high-speed, high-altitude spinner at Six Flags.

Some symptoms reported by our Austin patients with binocular vision dysfunction are:

  • Dizziness
  • Pounding headaches
  • Nausea
  • Feeling unsteady when walking; inability to walk straight
  • Motion sickness
  • Pain when moving the eyes
  • Anxiety when driving – many patients with a binocular vision dysfunction feel anxious when driving. (This may be due to the perception of stationary objects in your peripheral vision as moving images. Dizziness may also give you the sensation of rolling backwards, even though your foot is on the brake.)
  • Uneasiness when in a space with tall ceilings
  • Sensory overload; disorientation due to an excess of visual stimuli

Generally, certain actions or positions bring on these symptoms, such as:

  • Moving your head from side to side
  • Riding in the passenger seat of a car
  • Rounding curves while in a car
  • Driving at rapid speeds while watching other cars zip by on your side
  • Quickly standing from a seated position
  • Straightening up rapidly after bending over

Misdiagnosis of vertical heterophoria is common

Many of the symptoms of VH are not problems that you would naturally associate with a vision condition. As a result, misdiagnosis is typical, and patients are often told they have migraine disorder, an inner ear disorder, vertigo, or even MS. Other misdiagnoses include being told that the symptoms are due to certain foods you eat or insufficient sleep.

In addition, many people can easily pass a standard vision screening even if they have vertical heterophoria. That’s why only a specially trained optometrist can diagnose VH, such as our experienced eye doctor for binocular vision dysfunction in Austin, TX. Dr. Jennifer Catalasan is one of three optometrists who specializes in BVD in Texas!

Our optometrist can provide you with a detailed, dependable diagnosis and effective treatment in our advanced Austin eye care center.

Pink, Stinging Eyes?

Conjunctivitis, also called pink eye, is one of the most frequently seen eye diseases, especially in kids. It can be caused by viruses, bacteria or even allergies to pollen, chlorine in swimming pools, and ingredients in cosmetics, or other irritants, which touch the eyes. Some forms of conjunctivitis might be quite transmittable and quickly spread in school and at the office.

Conjunctivitis is seen when the conjunctiva, or thin transparent layer of tissue covering the white part of the eye, becomes inflamed. You can identify conjunctivitis if you notice eye redness, discharge, itching or swollen eyelids and a crusty discharge surrounding the eyes early in the day. Pink eye infections can be divided into three main types: viral, allergic and bacterial conjunctivitis.

The viral type is usually a result of a similar virus to that which produces the recognizable red, watery eyes, sore throat and runny nose of the common cold. The red, itchy, watery eyes caused by viral pink eye are likely to last from a week to two and then will clear up on their own. You may however, be able to reduce some of the discomfort by using soothing drops or compresses. Viral pink eye is transmittable until it is completely cleared up, so in the meantime maintain excellent hygiene, remove eye discharge and try to avoid using communal pillowcases or towels. If your son or daughter has viral conjunctivitis, he or she will have to be kept home from school for three days to a week until symptoms disappear.

A bacterial infection such as Staphylococcus or Streptococcus is usually treated with antibiotic eye drops or cream. One should notice an improvement within just a few days of antibiotic drops, but be sure to adhere to the full prescription dosage to prevent pink eye from recurring.

Allergic pink eye is not contagious. It is usually a result of a known allergy such as hay fever or pet allergies that sets off an allergic reaction in their eyes. First of all, to treat allergic pink eye, you should eliminate the irritant. Use cool compresses and artificial tears to relieve discomfort in mild cases. When the infection is more severe, your eye doctor might prescribe a medication such as an anti-inflammatory or antihistamine. In cases of chronic allergic pink eye, topical steroid eye drops could be used.

Pink eye should always be diagnosed by a qualified eye doctor in order to identify the type and best course of treatment. Never treat yourself! Keep in mind the sooner you begin treatment, the lower chance you have of giving pink eye to loved ones or prolonging your discomfort.
