What’s the Connection Between Sleep Apnea, Concussion, and Your Vision?

Sleep Apnea 640A recent comprehensive sleep study on people with post-concussion syndrome showed that 78% were diagnosed with sleep apnea.

What came first: the concussion or sleep apnea? Determining the answer can be difficult. People who don’t get enough sleep already exhibit some of the symptoms of post-concussion syndrome even when they haven’t had one.

What we do know is that there is a connection between sleep apnea and concussion. Sleep apnea affects the recovery from a concussion, and at the same time, the condition may result from a traumatic brain injury (TBI).

Where does vision come in?

Sleep Apnea and Concussions

For those having sustained a concussion, sleep is very important for a speedy and thorough recovery. A poor night’s sleep, as in the case of sleep apnea, may lead to impaired decision-making, cognitive loss, and symptoms of depression—all of which can interrupt the recovery process.

Obstructive sleep apnea, the most common form of sleep apnea, is caused by a physical collapse or blockage of the upper airway that interrupts breathing during sleep. This also reduces blood and oxygen flow to the brain, making it difficult for those with a concussion to recover.

A lesser known type of apnea is central sleep apnea. Unlike obstructive sleep apnea, this type is caused by a dysfunction in the brain that regulates breathing and sleep, which could also be affected by a TBI.

Sleep Apnea and Vision

As we all know, getting a good night’s sleep is essential to good health. There are a number of eye conditions that are exacerbated by poor sleep patterns and therefore may be associated with sleep apnea.

These include:

  • Floppy eyelid syndrome
  • Nonarteritic anterior ischemic optic neuropathy
  • Papilledema
  • Glaucoma
  • Swelling of the optic nerve
  • Retinal conditions

Getting your eyes checked regularly is important as it allows your eye doctor to rule out any eye disorders and prevent potential vision loss. This is all the more important if you’ve been diagnosed with sleep apnea.

Concussions and Vision

Concussions can have a significant impact on the functioning of the visual system. Post-trauma vision syndrome is a group of symptoms that cause eye coordination problems, dizziness, and blurred vision after a concussion.

The symptoms of post-trauma vision syndrome can include:

  • Headaches
  • Double vision
  • Dizziness
  • Focusing problems
  • Problems with walking and stride

Severe concussions can cause double vision and blindness, while mild concussions can affect vision and cause visual dysfunction.

How a Neuro-Optometrist Can Help

Neuro-optometrists can help post-TBI patients in ways that other health care providers may not be able to.

Neuro-optometry deals with how the visual system impacts daily functioning. By training the brain to control and communicate with the eyes more effectively, symptoms like headaches and dizziness can be significantly reduced or disappear altogether.

If you have experienced a concussion or suspect you may have sleep apnea, contact Vision Therapy Calgary to follow up on a diagnosis and treatment for any vision problems you may be having due to either condition.

10 Things About Vestibular Disorders You Probably Didn’t Know

tired woman 640The vestibular system is what helps us feel balanced and stable. People with vestibular disorders may experience symptoms like frequent dizzy spells, blurred vision, disorientation, falling, or stumbling. What many don’t know is that an optometrist trained in the field of neuro-optometry may be able to help. Read on to learn more about vestibular disorders and how we may be able to treat your dizziness.

10 Quick Facts About Vestibular Disorders

  1. Vestibular disorders affect more than 35% of adults over the age of 40.
  2. The vestibular system is made up of tiny fluid-filled parts within the inner ear, acting like a builder’s level, communicating with specific areas of the brain to process balance and movement.
  3. Other symptoms of vestibular disorders include nausea, fatigue, difficulty focusing on objects, poor concentration, difficulty reading, hearing loss, and ringing in the ear. Many of these symptoms may overlap with other conditions, so be sure to visit your doctor or eye doctor to rule out these conditions.
  4. Vestibular disorders can be caused by injury, disease, drug or chemical poisoning, ageing, and autoimmune diseases.
  5. Certain lifestyle changes can help ease symptoms of vestibular disorders. Reducing your intake of salt, caffeine, and alcohol could improve your condition.
  6. Vestibular disorders can be challenging to diagnose. Many patients report visiting four or more physicians over the course of several years before receiving a proper diagnosis.
  7. Some common vestibular disorders are benign paroxysmal positional vertigo (BPPV), labyrinthitis, vestibular neuritis, Meniere’s disease, and vestibular migraine.
  8. Sadly, patients with undiagnosed vestibular disorders may sometimes be perceived as lazy, anxious, inattentive, or attention-seeking.
  9. While there is no cure for vestibular disorders, some treatments can help cope with the condition, such as medications, physical therapy, lifestyle changes, and surgery. Neuro-optometric rehabilitation, which is a form of vision therapy, can be life-changing for some patients.
  10. There is hope! Neuro-optometrists who perform neuro-optometric rehabilitation therapy can help many patients suffering from dizziness or other symptoms of vestibular disorders by improving the way the brain processes information. In some cases, vestibular disorders are caused or exacerbated by poor coordination between the eyes and the brain. With neuro-optometric therapy, patients learn how to train their eyes and brain to work in unison, lessening or eliminating many of the symptoms associated with the condition, including dizziness and disorientation.

If you are experiencing dizziness, contact Vision Therapy Calgary to schedule your functional visual evaluation. If your vision is healthy and doesn’t seem to be contributing to your symptoms, we can refer you to other health care professionals who can help.

Frequently Asked Questions with Dr. George Fung

Q: Can you request lenses made from glass? Is glass still used for lenses?

  • A: Yes. Opticians still sometimes use glass for lenses. However, glass is not used very often because they aren’t as safe. If these glass lenses breaks, they can shatters into many pieces and can injure the eye. Glass lenses are much heavier than plastic lenses, so they can make your eyeglasses less comfortable to wear.

Q: Can a coating be added to eyeglasses to protect them from further scratches?

  • A: A protective coating can’t be added to a lens after it’s scratched. The coating is applied when the lens is manufactured and can’t be put on later.

Does Your Head Hurt? You Might Have Binocular Vision Dysfunction

headache womanHave you been struggling with headaches or migraines with little to no relief? If so, you might be suffering from binocular vision dysfunction (BVD).

A standard eye exam generally won’t identify BVD. That’s why it’s important to consult a neuro-optometrist if you’re experiencing headaches or migraines.

What is Binocular Vision Dysfunction?

Binocular vision dysfunction is a condition where your eyes are misaligned, leading the eye muscles to strain to transmit one clear image to your brain. This can result in head pain, migraines and several other symptoms. If the problem is BVD, a neuro-optometrist can diagnose the condition and provide effective treatment.

Common Symptoms of Binocular Vision Dysfunction

People with BVD typically experience some of these symptoms:

  • Sensitivity to light and glare
  • Double vision
  • Headaches and migraines
  • Eye strain
  • Fatigue or tiredness
  • Reduced attention span and concentration difficulties
  • Shadowed, overlapping or blurred vision
  • Dizziness
  • Light-headedness
  • Nausea
  • Anxiety
  • Motion sickness
  • Poor depth perception
  • Neck, upper back or shoulder pain

If BVD is the cause of your symptoms, specialized prismatic optical lenses that allow the eyes to regain their alignment can usually provide prompt relief.

Learning Disabilities and Reading Symptoms

Having even slightly misaligned eyes can also disrupt learning and reading.

Binocular vision dysfunction can tire your eyes while reading. Words may blend together, and you may skip lines or lose your place while reading.

A routine eye exam isn’t geared toward diagnosing BVD, so if your child complains of headaches and is struggling with schoolwork, get them assessed by your neuro-optometrist today.

Treatment for Your Headaches and Binocular Vision Dysfunction

Unlike standard eyeglasses, BVD lenses are specialized aligning lenses that allow your eyes to work together. Once your eyes are working together, the brain will receive one clear image. Your eye muscles will then be able to relax and release the tension that can cause headaches and migraines. Your eye doctor can play a significant role in treating these symptoms.

If you suffer from headaches, you may have BVD or another vision problem. Schedule a vision evaluation at Vision Therapy Calgary as soon as possible. The earlier a vision problem is detected, the sooner you can receive a comprehensive treatment plan to achieve clearer and more comfortable vision.

Vision Therapy Calgary serves patients from Bridgeland, Macleod Trail, Panorama Hills, S. Trail Crossing, and throughout Alberta.

Experiencing Headaches? Visual Problems May be the Cause

Experiencing Headaches 640We’ve all been through it: A headache that seems to pop up out of nowhere and suddenly makes the most routine tasks unpleasant, even impossible. What many people don’t know is that visual problems can cause mild to severe headaches.

Read on to discover what triggers vision-related headaches and how we can help you find relief.

Visual Problems That Can Cause Headaches

If you’re experiencing frequent headaches, here are some eye conditions that may be causing your pain:

  • Strabismus, also called visual misalignment or crossed eyes: when the eyes aren’t lining up with each other and produce images in double vision
  • Binocular vision dysfunction: when the eyes’ line of sight don’t match, and the eye muscles strain to produce a focused image
  • Presbyopia: commonly referred to as age-related farsightedness, when the eye’s natural lens thickens and becomes less flexible with age. Small text is harder to see up-close
  • Astigmatism, farsightedness and nearsightedness: when a misshapen cornea produces blurred or distorted vision and difficulty seeing either near or far-off objects

A note of caution.

If your headache is severe, something far more serious may be occurring. A sudden, severe headache can be a symptom of a stroke or a sight-threatening eye condition that requires immediate medical care.

This can include:

Acute angle-closure glaucoma: This occurs when fluid pressure builds inside the eye, leading to severe headaches, eye pain, blurry vision, and seeing halos around lit objects.

Giant cell arteritis: This occurs when the blood vessels’ inner linings swell, restricting blood flow. Symptoms include decreased vision and throbbing pain in the temples.

Treating the Visual Problems At the Root of Your Headaches

A comprehensive eye exam by a neuro-optometrist is the best way to determine whether you have visual challenges that could be causing your headaches. This eye exam checks for so much more than visual acuity; it often evaluates eye tracking and eye teaming, focusing, depth perception, oculomotor control, visual processing, peripheral awareness, and visual-vestibular integration.

If the exam shows that visual problems are at the root of your headaches, Dr. George Fung will provide a comprehensive treatment plan to strengthen your visual skills. This might include specific optical lenses, vision therapy, and advice on effective lifestyle changes.

Vision therapy can help you improve the way your eyes and brain communicate by utilizing prism lenses, personalized eye exercises, and often, computer-based games. Doing so often improves balance, coordination, and cognitive abilities, and can also reduce eye strain and alleviate (or even eliminate) vision-related headaches.

If you’re experiencing frequent headaches, visit Dr. George Fung for a thorough assessment of your symptoms, and to determine whether they’re being caused by visual problems. If so, we’ll offer treatment to alleviate your pain. We’re here to look out for your vision.
