The purpose of the study was to compare the efficacy and safety of a transconjunctival sutureless technique for pars plana vitrectomy using conventional 20-gauge instruments versus the conventional technique.
Clinical data were reviewed retrospectively for a consecutive series of patients who underwent transconjunctival sutureless vitrectomy (TSV; 38 eyes of 37 patients) and a control group who underwent vitrectomy using the conventional technique (38 eyes of 38 patients).
Eighty-nine of 107 sclerotomies (83.2%) in the TSV group self-sealed without the need for sutures. The TSV group showed earlier visual improvement from baseline, as early as 7 postoperative days, compared with 60 days in the conventional group. This was attributed to less surgically induced astigmatism in the TSV group; mean astigmatism at baseline and postoperative days 7, 30, and 90 was -1.05 diopter (D), -2.53 D, -1.32 D, and -1.09 D, respectively, in the TSV group and -1.09 D, -3.91 D (P = 0.0285), -2.57 D (P = 0.0203), and -1.18 D, respectively, in the conventional group. No serious complications were observed in either group, including postoperative hypotony, wound leakage, or endophthalmitis.
The 20-gauge TSV technique is as effective as the conventional technique and offers earlier postoperative recovery.
本研究旨在比较经结膜无缝线玻璃体切除术（TSV）联合传统 20G 器械与传统玻璃体切除术的疗效和安全性。
回顾性分析连续接受经结膜无缝线玻璃体切除术（TSV；37 例 38 眼）和接受传统玻璃体切除术（38 例 38 眼）的患者的临床资料。
在 TSV 组的 107 个巩膜切口（83.2%）中，有 89 个自行封闭，无需缝合。TSV 组的视力改善较常规组更早，术后 7 天即可观察到，而常规组则需要 60 天。这归因于 TSV 组术中诱导的散光更小；TSV 组在基线时和术后 7、30 和 90 天时的平均散光分别为-1.05 屈光度（D）、-2.53 D、-1.32 D 和-1.09 D，而常规组分别为-1.09 D、-3.91 D（P = 0.0285）、-2.57 D（P = 0.0203）和-1.18 D。两组均未出现严重并发症，包括术后低眼压、伤口渗漏或眼内炎。
20G TSV 技术与传统技术一样有效，并能更早地恢复术后视力。
