间歇性外斜视术后远期疗效及其影响因素分析

The long-term result of surgical correction in intermittent exotropia and its affect factors

目的探讨间歇性外斜视手术治疗的疗效和术后部分患者斜视回退的可能原因。方法对120例患者的术后一天眼位、术前有无双眼同时视功能、发病年龄、手术年龄、斜视类型与远期眼位的关系进行分析，寻找影响斜视回退的可能因素。结果120例随访平均25．34个月（12—50个月）。眼位：正位90例（75％），外斜29例（24．17％），内斜1例（0．83％）；术后远期眼位只与术后一天眼位和术前有无双眼同时视功能有关，而与发病年龄、手术年龄、斜视类型均无关。结论间歇性外斜视术后远期眼位与术后一天眼位和术前有无双眼同时视功能有明显相关性，术后一天过矫和术前有双眼同时视功能者可以获得较好的远期眼位。

Objective Studying return of postoperative,to analyze follow up data of 120 cases patients with intermittent exotropia of postoperative.Methods To analyze the relationship between the final eye position and the eye position of postoperative day one,age at onset,age at surgery,types of strabismus and preoperative binocular vision of the 120 patients and to find out possible affect factors of intermittent exotropia return.Results The final eye position were orthophoria in 90 cases （75%）, exotropia in 29 cases （24.17% ）and esotropia in 1 case（0.83%）.We find that the final eye position of intermittent exotropia operation did not correlated with age at onset,age at surgery and type of strabismus,but with the eye position postoperative day one and preoperative binocular vision.Conclusions A relatively good correlation was found between the postoperative day one eye position,preoperative binocular vision and the final outcome.Therefore, patients overcorrected at postoperative day one and had preoperative binocular vision can achieve relatively good final ocular alignment.
