To evaluate the surgical results of medial rectus muscle advancement for consecutive exotropia.
The medical data of patients that underwent reoperation between the years 2000-2020 were collected and reviewed retrospectively. Patients who underwent medial rectus advancement for consecutive exotropia were included. The exclusion criteria were follow-up period shorter than 6 months, past reoperations and restrictive or paralytic strabismus. Success was defined as alignment within 10 PD of orthophoria at last follow-up. The success group of patients was compared with the failure group.
Twenty patients with mean postoperative follow-up from the second surgery of 34.7 ± 29.2 months were included. On last follow-up examination, 9 (45.0%) patients had a successful result. Nine patients had undercorrection and 2 had overcorrection. The two groups were similar in the preoperative amount of mean exotropia, 23.3 ± 9.9 PD in the success group and 29.8 ± 14.0 PD in the failure group. On last follow-up examination, the amount of mean deviation was 2.7 ± 2.6 PD exotropia in the success group and 13.4 ± 23.6 PD exotropia in the failure group.
Medial rectus advancement for the correction of consecutive exotropia was successful in almost half of the cases. Failure was usually due to undercorrection.
评估内直肌后徙术治疗继发型外斜视的手术效果。
回顾性收集 2000 年至 2020 年期间接受再次手术的患者的临床资料。纳入因继发型外斜视行内直肌后徙术的患者。排除标准为随访时间少于 6 个月、既往手术史、限制性或麻痹性斜视。末次随访时斜视度在 10 PD 以内定义为手术成功。将手术成功组与手术失败组进行比较。
共纳入 20 例患者,平均第 2 次手术后随访时间为 34.7 ± 29.2 个月。末次随访时,9 例(45.0%)患者手术成功,9 例欠矫,2 例过矫。两组患者术前平均外斜视度相似,手术成功组为 23.3 ± 9.9 PD,手术失败组为 29.8 ± 14.0 PD。末次随访时,手术成功组平均斜视度为 2.7 ± 2.6 PD 外斜视,手术失败组为 13.4 ± 23.6 PD 外斜视。
内直肌后徙术治疗继发型外斜视的成功率接近一半,失败通常是由于欠矫所致。
