Vision Therapy for Neurological Conditions

Published on
July 15, 2022

Each year an estimated 1.5 million Americans sustain a traumatic brain injury (TBI). According to the Neuro Optometric Rehabilitation Association, 90% of traumatic brain injuries result in vision problems. 

Standard glasses are generally not an effective intervention for correcting visual deficiencies caused by traumatic brain injury, acute brain injury, and other neurological disorders and complications. In cases where glasses are not effective, vision therapy or neuro optometric rehabilitation may be necessary to improve daily living skills and learn and refine visual-motor skills.

What is vision therapy?

Vision therapy is similar to physical therapy, but instead of treating muscles in the body, it strengthens the eyes and ocular system. In addition to improving our patients' visual skills, it has also improved their emotional well-being. Having the ability to regain their independence and participate in daily activities increases their self-confidence. Both children and adults can benefit from vision therapy. 

What kinds of activities are done in vision therapy and how do they help someone who has experienced a traumatic brain injury? 

When working with a TBI patient in a neuro optometric rehabilitation program that includes vision therapy, our eye doctor and therapists will focus on the primary diagnosis that the patient is struggling with. We utilize a whole toolbox that includes therapy, syntonics, and prism lenses to improve the visual function and reduce symptoms of the patient. 

What is a vectogram used for in a vision therapy  program for TBI?

One of the things we will work on in vision therapy is eye teaming. Among the most common procedures we perform is vectograms, and this involves the use of a polarized target that is being moved towards and away from you while you wear polarized glasses. Vectograms help you learn to use your eyes to converge (look close) or diverge (look far).

How is accommodative dysfunction treated in a vision therapy program for TBI?

Another common diagnosis we see is difficulty with accommodative or focusing systems. We commonly use plus or minus lenses to treat it. Lenses such as these will either magnify or minimize images. In these cases, we move you back and forth in order to stimulate or relax the focusing muscles.

How does a peg board help in treating ocular motility disorders?

To treat ocular motility disorder, we will ask you to perform a peg board. At first, the board may be stationary, and you will have to insert the pegs without hitting the board. As you become more comfortable, we may turn on the peg board to where it is rotating while you perform the procedure.

How is peripheral vision improved in vision therapy?

Additionally, we work on peripheral integration, and in this case, we may use techniques such as the four chart fixation. So you are reading the rows of letters on the four charts and as you are going along the therapist may call out a different color and you have to see that in your periphery and tap that color. As an example, you might be reading the bottom row of a chart when the therapist calls out red, so you tap the red circle and keep reading.

Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.

Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

Vision Therapy has given or son the tools he needs to be able to scan and read the written word more effectively and efficiently.

He love working with John and these working sessions give him the motivation to gladly work on his homework assignments.

It amazed us to see the difference in the tracking of his eyes and along a line of it's from the beginning to the end of the treatment.

Dr. McBryar , Kristen and John  are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!

Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.

Thank you!

When we first came to the practice, my son did not have huge issues, but lots of small ones- trouble with reading, sports (hitting the baseball consistently), coordination, etc- that were not easily detectable,but when put together presented issues. The staff here were all very professional and loving towards him. While I was concerned in the reading, my son was concerned with the athletic side. Seeing improvement night off the bat gave him confidence that i have nor seen in him and made him want to not only Come to therapy, but also made him want to work hard. He has surpassed his grade level and above in reading and hit his first home run this year! Thank you!!!
