目的:探讨双眼或单眼内直肌缩短术或联合外直肌后退术治疗集合不足型共同性外斜视的疗效。方法:收集行双眼或单眼内直肌缩短术或联合外直肌后退术的集合不足型共同性外斜视患者181例,术前及术后1wk;2,6mo均行常规的眼科检查、斜视角测量、眼球运动及同视机检查,分别对眼位、视功能等结果进行统计学分析。结果:术后1wk;2,6mo,患者正位率分别为80.1%,83.7%和81.3%,眼位同术前相比有明显改善(P<0.01),术后双眼视功能同术前相比无明显恢复(P>0.05)。结论:对于集合不足型共同性外斜视,行双眼或单眼内直肌缩短术可获得较满意的效果。

AIM:To observe the effect of binocular or monocular medial rectus muscle resection in treatment of convergence insufficiency concomitant exotropia,sometimes lateral rectus muscles recession might be needed.METHODS:The selected 181 patients were performed binocular or monocular medial rectus muscle resection,sometimes might be associated with lateral rectus muscles recession.General ophthalmological examination,strabismometry,ocular movement and synoptophore were performed preoperation,1 week,2 months and 6 months postoperation.RESULTS:The orthotopic possibility were 80.1% after 1 week of operation,83.7% after 2 months of operation and 81.3% after 6 months of operation.The squint of post-operation had significant difference compared with that of preoperation(P<0.01).There was no significant difference between preoperation and postoperation with that of binocular visual functional restoration(P>0.05).CONCLUSION:Binocular or monocular medial rectus muscle resection in treatment of convergence insufficiency concomitant exotropia has satisfactory effect.
