To describe and evaluate the efficacy of a novel technique, scleral needling (SN), for securing 23- and 25-gauge leaking sclerotomies in microincision vitrectomy surgery.
A retrospective comparative review of consecutive cases of 23- and 25-gauge pars plana vitrectomy performed by a single vitreoretinal surgeon before the introduction of the SN technique (pre-SN; November 2016 to January 2017) and after the introduction of the SN technique (post-SN; November 2017 to January 2018) was conducted. The SN technique was implemented as an alternative to suturing, using a 30-gauge needle inserted perpendicularly through the full thickness of the sclera adjacent to the scleral opening, with the needle then immediately removed and sclerotomy closure confirmed.
A total of 203 eyes, 105 from pre-SN and 98 from post-SN, were included in the study. The number of eyes requiring suture closure was significantly reduced from 39% in the pre-SN group to 2% in the post-SN group (P < 0.001). The mean postoperative intraocular pressure and incidence of hypotony on Days 1 to 2, Days 3 to 20, and Days 21 to 50 was not significantly different between the pre-SN and post-SN groups. No major complications associated with the SN technique were noted during the study period.
The SN technique is a safe and simple method for effectively securing leaking sclerotomies in microincision vitrectomy surgery.
描述和评估一种新型技术——巩膜穿刺术(SN),用于固定微创玻璃体切割手术中 23 号和 25 号巩膜漏口。
对一位玻璃体视网膜外科医生在引入 SN 技术之前(预 SN;2016 年 11 月至 2017 年 1 月)和之后(后 SN;2017 年 11 月至 2018 年 1 月)连续进行的 23 号和 25 号经睫状体平坦部玻璃体切割术的连续病例进行回顾性比较分析。SN 技术是作为缝合的替代方法实施的,使用 30 号针垂直穿过靠近巩膜开口的巩膜全层,然后立即取出针,并确认巩膜切开术闭合。
共有 203 只眼纳入研究,其中 105 只眼来自预 SN 组,98 只眼来自后 SN 组。需要缝合闭合的眼数从预 SN 组的 39%显著减少到后 SN 组的 2%(P < 0.001)。两组间术后第 1 至 2 天、第 3 至 20 天和第 21 至 50 天的平均眼内压和低眼压发生率无显著差异。在研究期间,未发现与 SN 技术相关的主要并发症。
SN 技术是一种安全且简单的方法,可有效固定微创玻璃体切割手术中的漏口巩膜。
