Objective To study the distribution of the symptoms and signs of patients with convergence insufficiency and to evaluate the effectiveness of vision therapy. Method Forty patients were recruited in our Ophthalmology department. Twenty-three of them were male, the other seventy were female. Forty patients between 18 and 35 years old who were diagnosed with convergence insufficient asthenopia were randomly divided into two groups with 20 cases in cach group. Patiens in group A were treated by pen nib training system,patients B were treated by convergence and accommodation vision function training. Their oculomotor parameters were reviewed after twelve weeks. Results The authou found that after treated,both groups,near convergence points became nearer and fusional convergence increased significant-ly. The result of vision function training were better than those of pen nib training. At the same time the accommodative function was im-proved after reasonable vision therapy,including accommodative amplitude,positive relave accommodative,negative relative accommodative, accommodative reflect. The symptoms of vision fatigue relived remarkably. For pen nib training there was no difference in accommodative function. Conclusion Vision function training is better than pen nib training in convergence insufficient sathenopia.%目的：回顾性分析集合不足视疲劳患者的症状和体征及治疗的效果评价。方法：收集对屈光门诊诊断为集合不足型视疲劳的患者，共有40例，男23例，女17例，将上述年龄18~35岁的患者随机分为两组，每组20例，A组行笔尖训练，B组行集合调节视功能训练，12周后比较各项视功能参数。结果：两者训练方法对治疗集合不足视疲劳患者辐辏近点明显前移，正融像辐辏能力明显增强，而视功能训练组效果更为明显。同时，视功能训练还可以改善双眼调节功能，其中调节幅度、正相对调节、负相对调节、调节反应都有明显变化，从而缓解视疲劳症状，而笔尖训练组对于患者的调节功能状态没有明显改善。结论：规范的视觉训练对集合不足视疲劳具有确切疗效，而传统的笔尖训练则疗效不显著。
