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 efficacy of vitrectomy in the treatment of proliferative vitreoretinopathy. Methods C2 or more PVR with retinal detachment in 21 eyes, idiopathic PVR14 eyes, traumatic PVR7 eyes, C grade 9 eyes, D grade 12 eyes were treated with conventional vitrectomy combined with cerclage, membrane dissection, retinal incision, Gas or silicone oil filled additional surgical procedures. Results The follow-up ranged from 2 to 9 months. Retinal reattachment was found in 15 eyes (78.9%) and visual acuity was improved in 20 eyes (95.2%). 4 eyes failed surgery, all caused by recurrence of PVR. Conclusion Modern vitreous surgery is an ideal procedure for the treatment of severe PVR. Intraoperative skills is stripping the membrane, lifting the base of the vitreous traction on the retina. The main reason for the failure of surgery is PVR recurrence.
