To investigate whether intraoperative endolaser retinopexy around the sclerotomy site during pars plana vitrectomy can prevent the postoperative complication of retinal detachment (RD).
Two hundred and seventy-eight patients who had undergone 20-gauge pars plana vitrectomy for various vitreoretinal disorders were investigated retrospectively. Patients who had rhegmatogenous RD and who underwent panretinal photocoagulation for diabetic retinopathy were excluded. In Group 1, 152 patients had not undergone laser retinopexy around the sclerotomy site, and in Group 2, 126 patients had undergone laser retinopexy around the sclerotomy site. The incidence rates of postoperative RD were compared.
In Group 1, 7 cases (4.6%) of RD developed: 6 cases (3.9%) of sclerotomy-related retinal breaks, and 1 of a sclerotomy-unrelated retinal break. In Group 2, superior RD developed in 1 case (0.8%), but no sclerotomy-related retinal break was observed.
Endolaser retinopexy around the sclerotomy site is relatively simple to perform, without inducing particular complications. It is expected to reduce the development of postoperative RD (4.6% vs. 0.8%; P = 0.08) and especially sclerotomy-related RD (3.9% vs. 0%; P = 0.03).
研究在 20G 经睫状体平坦部玻璃体切割术中于巩膜切口处行眼内激光光凝能否预防术后视网膜脱离（RD）的发生。
回顾性分析 278 例行 20G 经睫状体平坦部玻璃体切割术治疗各种玻璃体视网膜疾病的患者的临床资料。排除孔源性 RD 患者及行全视网膜光凝治疗糖尿病性视网膜病变的患者。其中，152 例患者（组 1）未行巩膜切口处激光光凝，126 例患者（组 2）行巩膜切口处激光光凝。比较两组患者术后 RD 的发生率。
组 1 术后 RD 发生率为 4.6%（7/152），其中 6 例（3.9%）为巩膜切口相关性视网膜裂孔，1 例为非巩膜切口相关性视网膜裂孔；组 2 术后 RD 发生率为 0.8%（1/126），为上方 RD，未发现巩膜切口相关性视网膜裂孔。
巩膜切口处眼内激光光凝操作简单，无特殊并发症发生，有望降低术后 RD（4.6% vs. 0.8%；P=0.08），尤其是巩膜切口相关性 RD（3.9% vs. 0%；P=0.03）的发生率。
