方法：选取于我院眼科住院诊治行外斜视矫正术的患儿90例，收集其相关临床资料并术后回访1a，分析其影响术后眼位及双眼视功能的相关因素，包括发病年龄、斜视类型、手术年龄、就诊年龄、手术前远立体视功能、手术前近立体视功能、手术后眼位等。

结果：单因素及Logistic回归多因素分析结果提示：斜视类型、远期眼位、术前同视机立体视功能是婴幼儿期外斜视术后眼位及双眼视功能的影响因素(P<0.05)，而性别、发病年龄、手术年龄、术前Timus立体视功能、斜视临床分型不是婴幼儿期外斜视术后眼位及双眼视功能的影响因素(P>0.05)。

结论：婴幼儿期行外斜视术的斜视类型、远期眼位、术前同视机立体视功能是影响术后眼位及双眼功能的主要影响因素，为术后恢复的患儿眼位及双眼视功能提供一定的治疗依据。

METHODS: Ninety cases were selected in ophthalmology department of our hospital underwent external strabismus surgery. The clinical data was collected and follow up 1 year postoperatively. The factor affected eye position and binocular visual function after surgery were analyzed including before the age of onset, type of strabismus, operative age, age at diagnosis, surgery far stereo visual function, operation before the near stereopsis function after surgery, ocular and so on.

RESULTS: The types of strabismus and postoperative eye position positive rate and operation after far, binocular visual function recovery of closely related, the difference was statistically significant(P<0.05). Preoperative far stereo visual function and near stereo visual function affected postoperative distant stereoscopic vision function, and near stereoscopic visual function of main factors, the difference was statistically significant(P<0.05).

CONCLUSION: Infantile exotropia surgery preoperative far stereo visual function, near stereo visual function and the type of strabismus is main factors affected postoperative eye position and function. It can provide some treatment bases for postoperative recovery in children with eye position and binocular visual function.
