摘　　要：本文分析了49例49眼常规视网膜脱离复位术失败后的玻璃体视网膜显微手术.解剖成功率为75.51%,功能成功率为65.31%.作者认为这类病例常规手术失败的主要原因是增殖性玻璃体视两膜病变(PVR).冷凝、电凝及多次手术均刺激PVR形成.这类病人应行玻璃体手术才能使视网膜复位.玻璃体手术的疗效与PVR级别呈线性关系.手术时间以常规手术3个月后进行为宜.但为了保护视功能可适当提前.最后,作者讨论了玻璃体手术失败的原因,指出前段PVR及固定不确实是玻璃体手术失败的主要原因.In this paper we analyzed 49 cases (49 eyes) of mciro-vitreoretinal surgery for failed common retinal detachment repair. Reattacbment was achieved in 37 cases (75.51%) and final visual acuity of 10/200 or better was attained in 32 cases (65. 31%). It was suggested that common operation failure in these patients was due to PVR. Cryopeaxy, diathermy and repeat operation can render the formation of the PVR. Micro-vitreoretinal surgery should be performed on these patients. There was a linear relationship between the effectiveness and the degree of PVR. It is best to perform the surgery 3 months after common operation. Finally, the authors discuss the reasons for failure of vitreorednal surgery and conclude that the anterior PVR and the invalid fixing are the main reasons for failure of vitieoretinal surgery.
