Vision and Concussion: Post Trauma Vision Syndrome

Home » Wellbeing » Vision and Concussion: Post Trauma Vision Syndrome

Vision is a key part of our ability to perform even the simplest of our daily tasks. A concussion, also known as a mild traumatic brain injury (mTBI), is an injury to the brain that causes decreased brain function.

A mTBI can result in many symptoms including issues with balance, dizziness, cognitive function, speech and spatial orientation. One of the most common problems patients experience as a result of mTBI is Post Trauma Vision Syndrome (PTVS).

PTVS is a collection of signs and visual symptoms following mTBI. These symptoms can include double vision, blurry vision, headaches, dizziness, balance issues, perception of words moving on the page, inability to concentrate, disorientation, fatigue and many more.

Many visual conditions are commonly found post-mTBI including convergence issues (issues with eye alignment), accommodative dysfunction (focusing issues), and oculo-motor dysfunctions (Eye-tracking issues) and Visual Midline Shift Syndrome (a change in awareness of your location in space).

To assess for PTVS, a detailed visual assessment of both the eye muscle skills and the visual perceptual skills should be performed. This testing is not a part of a typical routine eye exam. Dr. Bokinac performs these assessments at Advance Vision Therapy for any patients suffering visual symptoms post-mTBI.

When visual deficiencies are identified during the assessment, a careful plan of therapy is put together to address these symptoms and visual conditions detected. Treatment for PTVS can include specialized prescription lenses, prism lenses, tinted lenses, binasal occlusion and vision therapy.

Vision therapy is a personalized program of intensive office-based visual training activities to help patients remediate deficient visual skills in both the eye muscle areas and visual processing areas. These activities also aim to reintegrate the visual skills with other systems such as vestibular, motor and auditory. To learn more check out our website.

If you are suffering symptoms following a mTBI, contact our office to book an assessment and see if we can help you.
