The effect of vision training on binocularly normal subjects

It is known that ocular motor dysfunction can be treated by utilizing vision therapy or vision training. However, the question remains on whether binocularly normal persons will have any significant change to their vergence ocular motor system if they go through vision training sessions. This study intends to explore that question. A total of five (n = 5) binocularly normal persons participated in this study (21 to 26 years of age). A haploscope with an integrated infrared eye tracking system manufactured by ISCAN presents vergence stimuli to the subject is used in this study to record the subjects´ eye movement data before and after an onset of vision therapy with a custom LabVIEW program. The vision therapy that is given to the subjects utilizes aspects of current therapy methods but in a virtual fashion. All processing and statistical analyses were done via MATLAB and Microsoft Excel. A trend for the eye movements toward becoming more critically damped after vision training was observed. Out of the five subjects, only Subject 1 showed a significant change in peak velocities. However, the time to peak velocity was significantly different across all subjects (p<;0.03).
