Seven patients with convergence insufficiency and related asthenopia underwent automated fusional convergence training. A matched-subjects control group crossover design was used to reduce placebo effects. All patients showed significant increases in vergence ranges with concurrent marked reduction of symptoms after training. All patients showed a flattening of and an increase in the base-out portion of their fixation disparity curve. Our results demonstrated the effectiveness of fusional vergence training in reducing asthenopia in these patients. Subsequent accommodation and vergence training using traditional orthoptic procedures yielded further reduction of asthenopia, as well as an increase in the base-out fusional range.
7例集合不足及相关视疲劳患者接受了自动融合性集合训练。采用匹配受试者对照组交叉设计以减少安慰剂效应。所有患者训练后集合范围显著增加，同时症状明显减轻。所有患者的注视差异曲线的基底向外部分变平且增加。我们的结果证明了融合性集合训练对减轻这些患者视疲劳的有效性。随后使用传统视光学程序进行的调节和集合训练进一步减轻了视疲劳，并增加了基底向外融合范围。
