Improvement of Vergence Movements by Vision Therapy Decreases K-ARS Scores of Symptomatic ADHD Children

초록

[Purpose] To determine whether the improvement of vergence movements by vision therapy can decrease the K-ARS scores of symptomatic ADHD children. [Methods] Eighty-one out of 1,123 children surveyed using the K-ARS, a parents'-reported questionnaire, led to 16 of these 81 children being showed scores of >= 19, and measurement of binocular function diagnosed as having convergence insufficiency. The 16 children were divided equally into a control group and a vision therapy group. [Results] After vision therapy for 12 weeks, near point convergence (4.38 +/- 0.69 cm) significantly neared compared to the near point convergence before vision therapy (11.50 +/- 2.28 cm), and both the break point (32.38 +/- 2.53.) and recovery point (19.75 +/- 2.11 Delta) of near positive fusional vergence significantly improved compared to their values before vision therapy (15.88 +/- 2.64 Delta, 6.38 +/- 6.70 Delta, respectively). Near exophoria after vision therapy (7.81 +/- 2.00 Delta BI) significantly decreased compared to its value before vision therapy (12.00 +/- 1.16 Delta BI). The K-ARS scores referring to symptomatic ADHD significantly decreased after vision therapy (17.13 +/- 2.84) compared to before vision therapy (23.25 +/- 1.49). [Conclusions] Convergence insufficiency symptoms are closely related to symptoms screened for ADHD, and vision therapy to improve vergence movements is an effective method of decreasing the K-ARS scores.
