Brain Injury & Concussion Assessments

If you’ve ever known someone who’s had a concussion, you may have noticed that they typically have vision problems along with other symptoms such as headache and dizziness.  Post Trauma Vision Syndrome can include:

  • seeing double
  • having difficulty focusing
  • losing track of lines when trying to read
  • have trouble looking at objects that are in motion
  • seeing movement when things are still
  • having eye pain and discomfort with reading and near work
  • difficulty looking at computer screens

This is because the visual system is often significantly affected by concussion. Eye muscle coordination and visual processing skills are likely to be compromised when the brain is hurt in concussion because so much of the brain is used for vision and eye control. This is usually not related to the ability to see 20/20.

Impaired Function: When there is a direct blow to the head, or whiplash, often there is functional damage to the visual process in the brain. Not uncommonly, there is no structural damage to the eye or brain so all structural tests appear normal. However, there can be profound functional loss that won’t necessarily be detected in a general assessment. Also, there can be a sudden mismatch induced between the vision and balance systems.

Assessment Includes:

  • Near and far visual focus
  • Focus change
  • Fixation-tracking (saccades-pursuits)
  • Visual midline shift

  • Visual perception
  • Central-peripheral integration
  • Vestibular-ocular connection


Concussion Baseline Testing

What is baseline testing?

Concussion baseline testing is a series of tests done prior to a sports season, or anytime prior to a known concussion to provide yourself and your healthcare provider information related to cognitive and neurological function to compare should an athlete get a concussion. As symptoms often disappear before the brain fully recovers, baseline testing provides valuable information, which may help healthcare practitioners make safer Return to Learn, Work and Play decisions. Baseline testing can make it easier to identify when a concussion or brain injury occurs, resulting in treatment sooner with better outcomes.

What can you expect during testing?

We test various areas of neurological, physical and cognitive functioning to provide us with both standardized and optometric measurements to compare if the patient were to suffer a concussion.

If you pair baseline testing with your child’s annual eye exam, we can further assess their optometric status to better determine if they suffer a concussion in the future.

In consideration of normal neurological development as children and teens grow, it is important to re-assess on a yearly basis.
