EXAMS – BRAIN INJURY/CONCUSSION

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:

  • Visual midline shift
