摘要目的:观察压贴三棱镜治疗儿童间歇性外斜视手术过矫导致继发性内斜视患者的眼位及立体视功能恢复效果。方法:前瞻性随机对照研究。纳入郑州大学附属儿童医院2019年1月至2024年1月80名间歇性外斜视手术过矫导致继发性内斜视患儿，按随机数字表法分为对照组(仅戴镜，40例)和研究组(戴镜＋压贴三棱镜，40例)，对比两组患者眼位、立体视及双眼视功能恢复效果。结果:研究组眼位正位率为90.00%(36/40)，高于对照组的65.00%(26/40)；欠矫率为7.50%(3/40)，低于对照组的35.00%(14/40)( χ2＝7.17、9.04， P＝0.007、0.003)。术后6个月，两组立体视率均提升( χ2研究组 ＝48.08, χ2对照组 ＝17.80；均 P<0.001)，黄斑中心凹立体视率均上升( χ2研究组 ＝16.81, χ2对照组 ＝5.00； P研究组<0.001， P对照组＝0.025)；研究组黄斑及周围立体视率显著提升( χ2＝12.47、6.28； P<0.001，0.012)，且研究组无立体视、黄斑中心凹立体视、黄斑立体视级周围立体视率优于对照组( χ2＝9.03、4.94、4.59、4.50， P＝0.003、0.026、0.032、0.034)。术后6个月，研究组存在立体视者为16例(40.00%)、存在融合功能者34例(85.00%)、存在同时视功能者21例(52.50%)，明显高于对照组的7例(17.50%)、19例(47.50%)、10例(25.00%)，差异均有统计学意义( χ2＝4.94、12.58、6.37， P＝0.026、<0.001、0.012)。 结论:应用压贴三棱镜治疗间歇性外斜视术后过矫导致继发性内斜视患儿，可提高眼位的正位率，促进恢复立体视和双眼视功能，减少无立体视觉的发生率。

abstractsObjective:To observe the efficacy of the recovery of eye position and stereoscopic function in children using a press-on prism for the treatment of secondary esotropia caused by overcorrection of intermittent exotropia surgery in children.Methods:A prospective randomized controlled study was conducted on 80 children with secondary esotropia caused by intermittent exotropia surgical overcorrection at Zhengzhou University Children’s Hospital from Jan. 2019 to Jan. 2024. The patients were divided into a control group (wearing glasses only, 40 cases) and a study group (wearing glasses and press-on prism, 40 cases) by using a random number table method. The recovery results of eye position, stereoscopic vision, and binocular vision function were compared between the two groups.Results:The positive rate of eye position of the study group was 90.00% (36/40), which was higher than the 65.00% (26/40) of the control group. The undercorrection rate was 7.50% (3/40), which was lower than the 35.00% (14/40) of the control group ( χ2=7.17, 9.04; P=0.007, 0.003). At 6 months after surgery, both groups showed improvements in stereoscopic vision rate ( χ2study group=48.08, χ2control group=17.80; all P<0.001), and the stereoscopic vision rate of the macular fovea increased ( χ2study group=16.81, χ2control group=5.00; Pstudy group<0.001, Pcontrol group=0.025); The study group had a significant improvement in macular and peripheral stereoscopic vision rate ( χ2=12.47, 6.28; P<0.001, 0.012), and had no stereoscopic vision, no macular foveal stereoscopic vision, and better peripheral stereoscopic vision rate compared with the control group ( χ2=9.03, 4.94, 4.59, 4.50; P=0.003, 0.026, 0.032, 0.034). At 6 months after surgery, the study group had 16 cases of stereoscopic vision (40.00%), 34 cases of fusion function (85.00%), and 21 cases of simultaneous visual function (52.50%), which were significantly higher than the 7 cases (17.50%), 19 cases (47.50%), and 10 cases (25.00%) which the control group had, and the differences were statistically significant ( χ2=4.94, 12.58, 6.37; P=0.026, <0.001, 0.012). Conclusion:Application of press-on prism in the treatment of secondary esotropia caused by overcorrection of intermittent exotropia surgery in children can improve the positive rate of eye position and promote the recovery of stereoscopic and binocular vision functions, and reduces the rate of non-stereoscopic vision.
