A concussion or Traumatic Brain Injury (TBI) or Acquired Brain Injury causes damage to the brain as a result of a blow to the head, stroke, or neurological dysfunction. It changes the way your brain functions. In children, the most common cause of concussions is a blow to the head during sports. In adults, motor vehicle accidents and falls are the most common cause.
The most common symptoms of a concussion are physical and cognitive:
Common physical symptoms of concussion are headaches, dizziness and vision problems.
Cognitive (mental) symptoms such as feeling in a fog and difficulty concentrating are widely experienced as well.

Concussions can have the following effects on the visual system:
Blurred Vision – can occur at distance, near or both and can last for days or months.
Accommodative Insufficiency – A reduced ability for the eyes to focus at near. This may cause constant or intermittent blurred vision when reading or working on a computer.
Convergence Insufficiency- a weakness in the eyes ability to work together at near which can cause headaches, eyestrain and even double vision when performing near activities.
Light Sensitivity (Photophobia) - can occur due to many types of brain injuries and causes discomfort in both indoor and outdoor lighting.
Oculo-Motor Dysfunction - poor control of eye movements and “tracking” which causes problems with many tasks throughout the day including reading and driving.
Reduced Visual Processing Speed and Reaction Time – Slower speed in processing visual information can cause problems with judging distance and speed of a ball and other players moving around.
Decreased Cognitive Ability during visual tasks - classroom and sports performance can be affected by problems with visual perception and understanding what is seen.
Our patients have had great success with reducing or eliminating these visual problems with various treatments, such as:
