摘　　要：目的 分析外直肌大量后退联合悬吊术治疗知觉性外斜视的疗效.方法 回顾性研究.收集2016年1月至2023年1月行手术治疗的知觉性外斜视33例.采用大量后退(8mm)联合悬吊(2~7mm)的超大量外直肌后退术,同时内直肌缩短4~7mm.术中以外斜眼过矫为内斜10~20 PD来决定内直肌缩短和外直肌悬吊的量.比较患者术前、后的眼球运动、水平、垂直斜视度以及旋转状态.结果 手术成功27例(81.82%),3例外斜复发,3例内斜大于+15PD.水平斜视度由术前-59.2±17.4 PD变为术后5.5±8.1PD,t=-16.608,P=0.000;眼球旋转状态FDA由7.5°±1.8°变为术后7.3°±1.5°,t=0.819,P=0.421.术后外展运动受限程度为-1.8±0.6级.结论 大量后退联合悬吊的超大量外直肌后退术治疗知觉性外斜视疗效好.Objective To analyze the effect of maximumal recession of lateral rectus muscle combined with suspension in treatment of sensory exotropia.Methods Using a retrospective study,33 cases of sensory exotropia were collected for surgery from January 2016 to January 2023.Maximumal recession(8mm)of lateral rectus muscle combined with suspension(2~7mm)was used,and the medial rectus muscle was resected(4~7mm).During the operation,initial postoperative deviation of esotropia 10~20 PD was used to determine the amount of medial rectus muscle resection and lateral rectus muscle suspension.The eye motor,horizontal deviation,vertical deviation and eye rotation were compared,preoperatively and postoperatively.Results The operation was successful in 27 cases(81.82%),3 with exotropia recurrence and 3 cases with esotropia greater than+15PD.The horizontal deviation was changed from preoperative-59.2±17.4PD to postoperative 5.5±8.1PD,with statistical differences(t=-16.608,P=0.000).The preoperative FDA(fovea disc angle)value was 7.5°±1.8°,and the postoperative was 7.3°±1.5°,with no statistical difference(t=0.819,P=0.421).The degree of the postoperative abduction limitation was-1.8±0.6 level.Conclusions The maximumal recession of lateral rectus muscle combined with suspension in treatment of sensory exotropia is effective.
