双眼外直肌后徙术治疗间歇性外斜视患儿的效果

Effects of bilateral lateral rectus recession in treatment of children with intermittent exotropia

目的:观察双眼外直肌后徙术治疗间歇性外斜视患儿的效果。方法:选取2021年6月至2022年6月该院收治的80例间歇性外斜视患儿进行前瞻性研究,按随机数字表法将其分为对照组与观察组各40例。对照组予以单眼外直肌后徙术联合内直肌缩短术治疗,观察组采用双眼外直肌后徙术治疗。比较两组矫正效果,手术前后斜视度、融合功能恢复率和立体视功能恢复率,以及复发率。结果:观察组正矫率高于对照组,欠矫率低于对照组,差异有统计学意义(P<0.05);术后,两组视近度、视远度均低于术前,且观察组低于对照组,差异有统计学意义(P<0.05);观察组融合功能恢复率和立体视功能恢复率均高于对照组,差异有统计学意义(P<0.05);观察组6个月、1年复发率均低于对照组,差异有统计学意义(P<0.05)。结论:双眼外直肌后徙术治疗间歇性外斜视患儿可提高正矫率、融合功能恢复率和立体视恢复率,降低欠矫率、斜视度和复发率,其效果优于单眼外直肌后徙术联合内直肌缩短术治疗。

Objective:To observe effects of bilateral lateral rectus recession in treatment of children with intermittent exotropia.Methods:A prospective study was conducted on 80 children with intermittent exotropia admitted to this hospital from June 2021 to June 2022.They were divided into control group and observation group according to the random number table method,40 cases in each group.The control group was treated with monocular lateral rectus recession combined with medial rectus shortening,while the observation group was treated with binocular lateral rectus recession.The correction effects,the strabismus degree before and after the surgery,the fusion function recovery rate,the stereoscopic function recovery rate,and the recurrence rate were compared between the two groups.Results:The correction rate of the observation group was higher than that of the control group,the undercorrection rate was lower than that of the control group,and the differences were statistically significant(P<0.05).After the surgery,the near vision and far vision of the two groups were lower than those before the surgery,those of the observation group were lower than the control group,and the differences were statistically significant(P<0.05).The fusion function recovery rate and the stereoscopic recovery rate in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).Further,the recurrence rates of 6 months and 1 year in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).Conclusions:Bilateral lateral rectus recession for the children with intermittent exotropia can improve the correction rate,the fusion function recovery rate and the stereoscopic recovery rate,and reduce the undercorrection rate,the strabismus degree and the recurrence rate.Moreover,it is superior to monocular lateral rectus recession combined with medial rectus shortening.
