Abstract

Background: Small conjunctival incision size is desirable in strabismus surgery under topical anesthesia.

Objective: To study the feasibility and tolerability of a small bulbar conjunctival incision (SB).

Design: Non-randomized feasibility pilot study.

Methods: After applying a 5-0 PGA (polyglycolic acid) traction suture, we did a 3-4 mm single conjunctival incision posterior and parallel to the rectus muscle insertion. A hang-back recession was done (6-0 PGA suture), and the conjunctiva closed (8-0 PGA suture). The outcome measures were feasibility, tolerability, and motor result.

Results: Twenty-five patients were included. The median pain scale score was 3/10, and the satisfaction Net Promoter Score was 72. Mean duration of a recession was 12 min (range: 9-14 min). Mean duration of inflammatory signs and hemorrhage were 2.2 days (95% CI, 1.4-2.9), and 8.5 days (95% CI, 7.1-9.9), respectively. Distance deviation at 2 months was 3.1 Prism Diopters (95% CI, 1.5-4.5).

Conclusion: SB is feasible and well tolerated for extraocular rectus muscle surgery.

单最小结膜切口治疗直肌：试点可行性研究。

背景：表面麻醉下斜视手术时，结膜切口宜小。目的：探讨球结膜小切口手术的可行性和耐受性。设计：非随机可行性试点研究。方法：应用5-0 PGA（聚乙醇酸）牵引缝合后，在直肌止点后方平行做一个3-4 mm的单结膜切口。采用6-0 PGA缝线进行悬吊后退缩，结膜闭合（8-0 PGA缝线）。结果指标为可行性、耐受性和运动结果。结果：纳入25例患者。疼痛量表评分中位数为3/10分，满意度净推荐值为72分。衰退的平均持续时间为12分钟（范围：9-14分钟）。炎症症状和出血的平均持续时间分别为2.2天（95% CI, 1.4-2.9）和8.5天（95% CI, 7.1-9.9）。2个月时距离偏差为3.1 Prism Diopters （95% CI, 1.5-4.5）。结论：SB用于眼外直肌手术是可行且耐受性良好的。
