摘要
目的 评估玻璃体手术治疗增殖性玻璃体视网膜病变的疗效。方法 C2 级以上 PVR合并视网膜脱离 2 1眼 ,特发性 PVR14眼 ,外伤性 PVR7眼 ,C级 9眼 ,D级 12眼 ,均作常规玻璃体切除术联合环扎、膜剥离、视网膜切开、气体或硅油填充等附加术式。结果 随访 2～ 9个月 ,视网膜复位 15眼 (78.9% ) ,视力提高 2 0眼 (95 .2 % )。4眼手术失败 ,均系 PVR再次复发所致。结论 现代玻璃体手术是治疗严重 PVR的理想术式。术中技巧在于剥膜、解除基底部玻璃体对视网膜的牵引。手术失败的主要原因是 PVR复发。
Objective To evaluate the effect of vitrectomy in the proliferative vitreoretinopathy(PVR).Methods 21 cases of PVR(≥Grade-C 2)with retinal detachment were treated by vitrectomy,and scleral buckling,membrane peeling,retinotomy,gas or silicon oil tamponade.Results The retina was reattached in a rate of 78.9% in 2-9 months postoperatively,visual acuity improved in 20 eyes(95.2%).4 eyes failed because of PVR recurrent.Conclusion Modern vitrectomy is optimal operation for PVR.The most important technique is membrane peeling and eliminating the traction of vitreous base.PVR recurrent is major reason of failure.
