To evaluate the surgical results of medial rectus (MR) muscle advancement with or without recession of the antagonist muscle for consecutive exotropia.
Medical records of patients with consecutive exotropia ( = 27) were retrospectively reviewed. All patients received one-eye surgery with MR advancement, lateral rectus (LR) recession, or combined surgery. The pre- and post-operative angle of deviation was recorded. Characteristics were compared between groups. The follow-up period was at least 3 months.
The overall successful rate was 62.96%, with 50% in MR advancement group, 60% in LR recession group, and 71.4% in combined group. Patients in combined group had larger preoperative deviation. There were comparable surgical results between patients with inferior oblique (IO) muscle overaction receiving correction simultaneously and patients without IO muscle overaction.
The overall surgical successful rate for consecutive exotropia in this study was 62.96%. Combined MR advancement and LR recession yielded better results than MR advancement or LR recession alone although it was not statistically significant.
评估内直肌（MR）前徙联合或不联合拮抗肌后徙治疗连续性外斜视的手术效果。
回顾性分析连续性外斜视患者（n = 27）的病历。所有患者均接受单眼手术，包括MR前徙、外直肌（LR）后徙或联合手术。记录术前和术后的斜视角度。比较各组患者的特征。随访期至少3个月。
总体成功率为62.96%，其中MR前徙组为50%，LR后徙组为60%，联合组为71.4%。联合组患者术前斜视角度更大。同时接受下斜肌（IO）亢进矫正的患者与未接受IO亢进矫正的患者手术效果相当。
本研究中连续性外斜视的总体手术成功率为62.96%。MR前徙联合LR后徙的效果优于单纯MR前徙或LR后徙，尽管差异无统计学意义。
