The purpose of the present study was to evaluate the effects of vision therapy in a school setting in which elementary school children, enrolled in a reading-mentoring program, Caring Adults Teaching Children How (CATCH), were trained as a group. The experimental goal was to improve visual-motor and visual perceptual skills, with the use of vision therapy in short sessions given weekly at school, to children with reading difficulties. Sixty students were selected after the use of the Developmental Eye Movement test’s (DEM) exclusion criteria and were randomly assigned into one of two groups: vision therapy and non-therapy. Both groups received CATCH tutorial visits once a week for 50 minutes. In addition, the therapy group received a weekly 30 minute activity session in which three activities were completed from the following: oculomotor, accommodation, binocularity, visual motor and visual memory. The results revealed that vertical and horizontal eye movements and accommodative facility were significantly improved after 22 sessions of group vision therapy. These improvements were related to attentional mechanisms leading to improved reading abilities. We believe this preliminary study gives evidence of the advantages of a program whereby vision therapy is provided in the elementary school setting to advance deficient visual skills that are related to learning and cognitive enhancement.


Developmental Eye Movement Vertical - There was a statistically significant improvement in vertical eye tracking in the therapy group compared to those not treated when tested at the midterm point, F (1,45) = 3.81, p< .05. As seen in Figure 1A, the therapy group at each grade level had a greater percentile vertical tracking score than the non-therapy group. End of year vertical tracking scores compared to midterm scores showed another significant treatment effect, that is, while each group improved their scores, the therapy group scores remained higher, F (1, 43) = 5.00, p< .03 (Figure 1B). When comparing all 3 vertical eye tracking scores, there was a significant improvement across the year for the group receiving therapy, F (1,43) = 4.92, p< .03, demonstrating a continued improvement in the therapy group. There was no significant difference between grades or treatment interaction with grade. Horizontal - Testing for horizontal eye tracking at mid year showed a statistically significant increase in performance for those receiving therapy, F (1, 46) = 5.54, p< .02 (Figure 2A). Midterm horizontal tracking scores compared to the final scores produced a statistically significant interaction between treatment group and time, F (1, 41) = 5.21, p< .03 (Figure 2B). This implies that, whereas the therapy group demonstrated most of their improvement in DEM-horizontal in the first half of the year, the non-therapy subjects had an equal amount of improvement occurring in the second half of the year.


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!!!
