PURPOSE
To evaluate the efficacy of Faden procedure for correcting consecutive esotropia (ET).
METHODS
This retrospective study included 25 children who developed consecutive ET after primary bilateral lateral rectus (BLR) recession and underwent medial rectus (MR) recession with the Faden procedure (Faden group) or MR recession only (control group) between 2013 and 2018. Postoperative deviation angles were evaluated at each follow-ups until postoperative 6-month visit. Surgical motor and sensory outcomes were compared between Faden group and control group.
RESULTS
There were 10 children in the Faden group and 15 children in the control group. While the Faden group maintained orthotropia without any small deviation until postoperative 6-month visit, the control group showed wider distribution of postoperative deviation angles (1 patient with small angle esodeviation < 5 PD, 3 patients with esodeviation > 5 PD, and 3 patients with exodeviation < 5 PD). In the Faden group, seven patients have good stereopsis (60″ or better) and three patients demonstrated fair stereopsis (80-3000″) after surgery. In the control group, four, eight, and three patients showed good, fair, and nil stereopsis (P = 0.026), respectively.
CONCLUSION
MR recession combined with Faden operation could be a good surgical option for managing consecutive ET.
目的
评估 Faden 手术矫正继发型内斜视（ET）的疗效。
方法
本回顾性研究纳入了 2013 年至 2018 年间因初次双侧外直肌（BLR）后退术后出现继发型 ET 而接受内直肌（MR）后退联合 Faden 手术（Faden 组）或单纯 MR 后退（对照组）的 25 例儿童。在每次随访中评估术后斜视角度，直至术后 6 个月就诊。比较 Faden 组和对照组的手术运动和感觉结果。
结果
Faden 组有 10 例儿童，对照组有 15 例儿童。Faden 组在术后 6 个月就诊前保持正位且无小角度斜视，而对照组术后斜视角度分布较宽（1 例小角度内斜视 < 5 PD，3 例内斜视 > 5 PD，3 例外斜视 < 5 PD）。Faden 组术后 7 例患者具有良好的立体视（60″或以上），3 例患者具有中等立体视（80-3000″）。对照组术后分别有 4、8、3 例患者具有良好、中等和无立体视（P=0.026）。
结论
MR 后退联合 Faden 手术可能是治疗继发型 ET 的一种较好的手术选择。
