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!

What is binocular vision dysfunction and how do I know if I have it?

Binocular vision dysfunction, or BVD for short, is a visual condition that occurs when both eyes cannot coordinate properly. As a result, the line of sight from one eye is slightly misaligned with the other eye. This misalignment heavily stresses your eye muscles as they try to correct the problem and achieve single focus vision.

Diagnosing binocular vision dysfunction can be complicated, and many people suffer from the disturbing symptoms for years before getting a proper diagnosis. Dr. Jennifer Catalasan, our neurovisual optometrist in Austin, TX, is knowledgeable and experienced in diagnosing BVD, and we can spot the signs immediately – so you won’t need to suffer any longer.

What are the signs of binocular vision dysfunction?

If you have BVD, you may experience some or even all of the following symptoms:

  • Dizziness
  • Nausea
  • Double vision
  • Losing your place while reading
  • Headaches or migraines
  • Neck/shoulder strain (from twisting your head to focus)
  • Poor depth perception
  • Problems with balance and/or coordination
  • Motion sickness
  • Panic attacks when driving
  • Agoraphobia (uneasiness in large places)
  • Disorientation
  • Blurry vision

If you suffer from these symptoms and can’t find lasting relief, visit our Austin, TX, eye doctor for a specialized eye exam to diagnose and treat binocular vision dysfunction.

How does someone develop binocular vision dysfunction?

BVD has a tendency to run in families, and you can be born with it. It can also result from a head injury, stroke, and other neurological disorders. Non-hereditary binocular vision dysfunction is commonly caused by car accidents.

How is binocular vision dysfunction diagnosed?

A comprehensive eye exam by a qualified eye doctor is the only reliable way to diagnose BVD. The first step of diagnosis involves filling out a questionnaire designed by professional eye care researchers. These questions offer an efficient way to evaluate if you might have any form of binocular vision dysfunction. At Lakeline NeuroVisual Medicine, we have two customized questionnaires for our patients to take, one for adults (age 14 and older) and one for children (age 13 and younger), respectively. Once we assess your answers, our Austin eye doctor will perform an eye exam and a neurovisual evaluation to determine if your eyes are in alignment or not.

What happens after binocular vision dysfunction is diagnosed?

Prismatic eyeglasses lenses can offer an effective way to relieve the stress and fatigue placed on your visual system. In general, our patients report a significant reduction in their BVD symptoms almost immediately after putting on prismatic lenses. Within a few weeks of visiting for follow-up appointments to fine-tune the customized prismatic prescription, the vast majority of our patients experience a 70-80% reduction of their symptoms!

Have you made multiple trips to other eye care specialists without any real improvement in your vision condition?

This is a typical sign of binocular vision dysfunction, which our Neurovisual Medicine specialist, Dr. Jennifer Catalasan, can diagnose reliably and treat to alleviate your symptoms once and for all. Contact us for an evaluation to diagnose or rule out binocular vision dysfunction – book an eye exam in our Austin, TX, office.

Micro-Prism Lenses May Be The Answer

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!
