通过一项回顾性病例对照研究，评价了25 G玻璃体切除术中两步斜切口手术对术后低眼压的疗效。25号玻璃体切除术中的经结膜切口分为两步：用显微玻璃体视网膜刀片穿透，然后用钝套管针穿透器械穿透。两步法89眼，常规切口68眼。比较术后第1天、术后1周、术后1个月低眼压（眼压< 6 mmHg）的发生率。术后第1天，两步法组2只眼（2%）和传统切口组12只眼（18%）出现低眼压（P = 0.001，Fisher精确概率检验）。两组术前眼压无显著差异，但术后第一天两步法组显著高于传统方法组（P = 0.001，Wilcoxon秩检验）。25G玻璃体切割联合两步斜切口将减少术后第一天低眼压的发生率。
The efficacy of a two-step, oblique incision procedure during 25-gauge vitrectomy on postoperative hypotony was evaluated by a retrospective, case-control study. The transconjunctival incision during 25-gauge vitrectomy was made in two steps: penetration with a microvitreoretinal blade followed by a penetrater instrument of a blunt trocar. The two-step procedure was performed on 89 eyes and with the conventional incision on 68 eyes. The incidence of hypotony (intraocular pressure < 6 mmHg) on the first postoperative day and after 1 week and 1 month was compared. Hypotony was found in two eyes (2%) with the two-step method and 12 eyes (18%) with the conventional incision on the first postoperative day (P = 0.001, Fisher's exact probability test). The preoperative intraocular pressure was not significantly different in the two groups but was significantly higher in the two-step group than in the conventional method group on the first postoperative day (P = 0.001, Wilcoxon rank test). Twenty-five-gauge vitrectomy with two-step oblique incisions will reduce the incidence of postoperative hypotony on the first postoperative day.
