目的：探讨玻璃体视网膜显微手术中发生医源性视网膜裂孔的原因和处理措施。方法：回顾性分析本院１９９４年７月至１９９６年３月玻璃体视网膜显微手术中发生的医源性视网膜裂孔２４眼（４０个裂孔）的原因、位置和术中术后的处理情况。结果：２４只眼中增殖性玻璃体视网膜病变（ｐｒｏｌｉｆｅｒａｔｉｖｅｖｉｔｒｅｏｒｅｔｉｎｏｐａｔｈｙ，ＰＶＲ）１６只眼，外伤性ＰＶＲ５只眼，牵拉性视网膜脱离３只眼。对新裂孔的处理采用巩膜冷凝、硅胶填压、眼内电凝、眼内填充和术后激光光凝。下方和手术嵴后医源性视网膜裂孔分别占７０％和９２％。平均随访５个月，视网膜完全复位和黄斑复位１７只眼，视力改善１９只眼，均在０．０２以上。结论：医源性视网膜裂孔是一种严重的并发症，应在术中、术后采取措施促使其封闭
Objective: To investigate the causes and treatment of iatrogenic retinal tears in vitreoretinal microsurgery. Methods: Retrospective analysis of the hospital from July 1994 to March 1996 vitreoretinal microsurgery occurred in iatrogenic retinal holes 24 (40 holes) causes, location and postoperative management. Results: Twenty-four eyes of proliferative vitreoretinopathy (PVR), 24 eyes of traumatic PVR and 3 eyes of traction-induced retinal detachment were observed in 24 eyes. The treatment of new holes using scleral condensation, silicone packing, intraocular coagulation, intraocular filling and postoperative laser photocoagulation. Below and surgical ridges iridoid retinal holes accounted for 70% and 92%. The average follow-up of 5 months, retinal complete reset and macular reduction in 17 eyes, visual acuity improved in 19 eyes, were more than 0.02. Conclusion: iatrogenic retinal breaks are a serious complication and should be closed intraoperatively and postoperatively
