摘　　要：目的探讨对间歇性外斜视患者应用手术治疗后双眼视功能的恢复状况。方法选取2018年1月至2019年12月安徽省阜阳市人民医院收治的间歇性外斜视患者80例,对患者进行手术治疗,观察患者治疗前后手术正位率、双眼视功能以及斜视度差、立体视锐度差的差异。结果手术后患者正位率明显高于手术前[88.8%(71/80)比40.0%(32/80)],欠矫率以及过矫率明显低于手术前[7.5%(6/80)比36.2%(29/80)、3.8%(3/80)比23.8%(19/80)],差异均有统计学意义(P<0.05)。手术后患者同时视(Ⅰ级)率、近立体视率、融合(Ⅱ级)率、远立体视(Ⅲ级)率均高于术前[91.2%(73/80)比26.2%(21/80)、17.5%(14/80)比5.0%(4/80)、21.2%(17/80)比3.8%(3/80)、33.8%(27/80)比0],差异均有统计学意义(P<0.05)。手术后患者斜视度差、立体视锐度差、融合功能差值均低于术前[(29.5 ± 2.8)Δ比(46.2 ± 3.1)Δ、(190.6 ± 19.4)°比(240.3 ± 18.5)°、(3.1 ± 0.8)°比(4.3 ± 0.6)°],差异有统计学意义(P<0.05)。结论对间歇性外斜视患者采用合适的手术方式是至关重要的,能促进患者正位率的提高,明显改善患者双眼视功能,取得理想的治疗效果。Objective To investigate the status of binocular visual function before and after operation in children with intermittent exotropia.Methods Eighty patients with intermittent exotropia admitted to Fuyang People′s Hospital from January 2018 to December 2019 were selected for surgical treatment,and the differences in orthotopic rate,binocular visual function,strabismus and stereoscopic sharpness before and after treatment were observed.Results The orthostatic rate was significantly higher than that before the operation[88.8%(71/80)vs.40.0%(32/80)],the undercorrection rate and overcorrection rate were lower than those before the operation[7.5%(6/80)vs.36.2%(29/80),3.8%(3/80)vs.23.8%(19/80)],and there were significant differences(P<0.05).The rates of simultaneous vision(Ⅰgrade),near stereopsis,fusion faculty(Ⅱgrade),and far stereopsis(Ⅲgrade)after operation were higher than those before operation[91.2%(73/80)vs.26.2%(21/80),17.5%(14/80)vs.5.0%(4/80),21.2%(17/80)vs.3.8%(3/80),33.8%(27/80)vs.0],and there were significant differences(P<0.05).The strabismus angle,stereoscopic vision sensitivity,fusion faculty degree after operation were lower than those before operation[(29.5±2.8)Δvs.(46.2±3.1)Δ,(190.6±19.4)°vs.(240.3±18.5)°,(3.1±0.8)°vs.(4.3±0.6)°],and there were significant differences(P<0.05).Conclusions It is very important to adopt appropriate surgical methods for children with intermittent exotropia,which can promote the improvement of orthotopic rate,significantly improve the binocular visual function of children,and achieve ideal therapeutic effect.
