The purpose of this study was to determine the efficacy of computerized fusional vergence therapy and the effect of two different vergence training velocities. Six subjects received positive vergence training using a slow vergence training rate (0.75 delta/s) and six subjects received positive vergence training using a fast vergence training rate (5.00 delta/s). Six subjects served as controls and did not receive therapy. The duration of therapy was 80 min over a period of 4 weeks. All training activities were monitored. All vergence evaluations were double masked. Subjects using a slow training rate showed significant increases in positive vergence ranges as measured with the major amblyoscope, whereas subjects training with fast rates did not. We conclude that vergence therapy using a computerized video display is an effective technique for increasing the amplitudes of positive fusional vergence and that slower rates are more productive than faster rates.
本研究的目的是确定计算机化融合性聚散训练的疗效以及两种不同聚散训练速度的效果。六名受试者以缓慢的聚散训练速度（0.75棱镜度/秒）接受正性聚散训练，六名受试者以快速的聚散训练速度（5.00棱镜度/秒）接受正性聚散训练。六名受试者作为对照组，未接受治疗。治疗持续时间为4周，共80分钟。所有训练活动均受到监测。所有聚散评估均采用双盲法。使用缓慢训练速度的受试者在用主觉验光仪测量时，正性聚散范围有显著增加，而使用快速训练速度的受试者则没有。我们得出结论，使用计算机化视频显示器进行聚散训练是增加正性融合性聚散幅度的有效技术，且较慢的速度比较快的速度更有效。
