eye doctor checking patient's eye using light

Your eyesight is vital for almost every task you perform. Binocular vision lets you see a single image, despite having two eyes. Your brain undergoes an amazing, complex process to fuse two separate pictures into one in-focus image. For this to happen, your eyes need to be aligned perfectly and work in sync constantly.

Binocular Vision Dysfunction (BVD) occurs when your eyes are no longer able to work together as a team. This can happen even if you have 20/20 vision. Because of this, BVD is often misdiagnosed. That’s why it’s important to see a qualified, experienced eye doctor who can listen to your symptoms, assess your vision, and make an accurate diagnosis.

In this post, your trusted eye center in Surrey, BC, shares more information on this topic:

How Do I Know if I Have Binocular Vision Dysfunction or Another Vision Problem?

Binocular vision dysfunction is a complex vision condition that interferes with your ability to see clearly.  BVD occurs when your eyes are not working together properly to create a single image. Without binocular vision, you would have double vision, or be unable to see properly.

Binocular vision dysfunction does not just result in blurry vision.  A typical eye exam will not spot this condition. Your eye doctor will examine your eyes and ask you questions to determine if you are experiencing symptoms that are related to vision, such as headaches, double vision, and blurry vision.

What Causes Binocular Vision Dysfunction?

Binocular vision dysfunction can be caused by many different issues, including:

  • Lack of coordination between the eyes
  • Poor focusing and eye movement
  • Muscle strain
  • Nerve damage
  • Eyelid problems
  • Eyeball shape
  • Eye disease

Diagnosing and Treating Binocular Vision Dysfunction

If you have any symptoms, you should have them examined by a qualified eye doctor. A thorough eye exam will include a visual acuity test, dilated pupil examination, and a cover test to test your eye coordination. Depending on the results of your exam, additional testing may be done, including:

  • Visual field test
  • Eye muscle balance test
  • Ocular alignment test
  • Accommodative and binocular vision test
  • Dilated retinal examination
  • Electrophysiology tests
  • Optical coherence tomography (OCT)
  • Electroretinogram (ERG)
  • Tear film break-up time test
  • Visual evoked potential (VEP)

If an underlying condition is found, a referral to a medical specialist may be necessary. Your ophthalmologist may recommend additional treatments, including eye exercises and vision therapy.
