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.
