Oculomotor dysfunction is a common symptom of post-concussion syn-drome (PCS). In this study, the efficacy of Vision Therapy (VT) for the treatment of PCS-related symptoms of the visual system was investigated retrospectively. Overall, 56 patients were selected, all of whom presented with clinical impairment of at least one measure of oculomotor function-ing. Activities related to VT were wide-ranging and case-dependent, but all aimed to improve one of the five main areas of visual function. Following the completion of VT, all patients demonstrated statistically or clinically significant improvements, as defined by the use of Morgan’s norms, in atleast one measure of oculomotor functioning related to PCS. In general, improvements in measures of oculomotor functioning were greatest for near point of convergence, vergence facility and accommodative facility. Patients who received 20 sessions of VT had improved and less variable outcomes than those who received 5-10 sessions of VT. In addition, VT im-proved symptoms of visual discomfort in patients presenting with PCS. The results of this retrospective analysis demonstrate significant improvements in measured outcomes for all patients who received VT, and support VT as a treatment option for symptoms of PCS.
The results of this retrospective analysis support the findings of previous studies and demonstrate statistically and clinically significant improvements of measured oculomotor functioning in patients presenting with oculomotor deficiencies associated with PCS and support VT as a viable treatment option for associated symptoms. Further-more, the present results suggest that longer treatment times (20 VT sessions) might improve measured outcomes compared to those in patients who receive 10 or less VT sessions; however, the impact of delayed VT treatment re-mains unclear. Although no placebo group was available in this study, the results demonstrate significant improve-ments in measured outcomes for all patients receiving VT and support VT as a treatment option for PCS.
