[摘要] 目的：探讨融合性辐辏异常所致视疲劳的同视机训练治疗效果。方法：对融合性辐辏异常所致视疲劳患者使用同视机进行融合性辐辏范围扩展训练或敏捷度训练，观察治疗前后融合性辐辏范围、敏捷度及视疲劳症状变化。结果：治疗后患者融合性辐辏范围扩大、敏捷度提高、症状消失，治疗前后比较差异均有显著统计学意义(P<0.01)。结论：视疲劳患者应常规进行同视机检查。对于存在融合性辐辏异常者，使用同视机进行融合性辐辏范围扩展训练或敏捷度训练效果好。

[Abstract] Objective: To investigate the effect of major amblyoscope in the treatment of asthenopia caused by anomalies of fusional convergence. Methods: Patients of asthenopia caused by anomalies of fusional convergence were widen the scope or improved the agility of fusional convergence with major amblyoscope. The changes of the scope of the agility and the symptoms of patients before and after treatment were observed. Results: The scope of fusional convergence were widened. The agility of fusional convergence were improved and the symptoms were disappeared.There were significant differences when compared the scopes,the agility and the symptoms before the treatment with those after the treatment (P<0.01). Conclusion: We should exam patients of asthenopia by major amblyoscope.The treatment,widen the scope or improved the agility of fusional convergence by major amblyoscope, is very effective to patients who suffered from anomalies of fusional convergence.

视疲劳是一种眼科常见疾病，患者于近距离用眼时出现视力障碍、肌源性眼痛、眼部慢性炎症，甚至引起头痛、记忆力减退、失眠等全身症状，严重影响正常的工作生活。视疲劳产生的原因有多种，本文主要探讨融合性辐辏异常所致视疲劳及其同视机训练治疗方法。
1对象和方法
1.1对象
2009年1月~2010年4月我院确诊融合性辐辏异常所致视疲劳患者49例。其中，融合性辐辏范围变小者33例，男19例，女14例；年龄17~48岁，平均(29.24±7.60)岁；屈光状态(0~-6.00) D，平均(-2.96±1.65) D；视近水平斜视(-3°~-8°)，平均(-5.45°±1.30°)；视远水平斜视(-1°~-4°)，平均(-2.21°±1.22°)。融合性辐辏敏捷度下降者16例，男10例，女6例；年龄19~46岁，平均(31.75±7.90)岁；屈光状态(0~-5.25) D，平均(-2.44±1.56) D；视近水平斜视(-2°~-6°)，平均(-3.81°±1.17°)；视远水平斜视(0°~-4°)，平均(-1.75°±1.18°)。
1.2 入选标准
①有明确视疲劳症状，根据症状轻重分为4级。0级：无症状；1级：用眼后出现眼部酸胀等症状，休息后很快恢复，对学习和工作无明显影响；2级：有明显的眼部症状影响学习和工作；3级：除有明显的眼部症状和视作业不能持久外 ......
