方法：回顾性分析晚期增殖性糖尿病视网膜病变患者38例45眼经玻璃体视网膜手术治疗后的临床资料，分析手术后视力改善情况和手术的并发症。

结果：随访患者45眼，术后视力0.05以上者从术前14眼(31.1%)提高到术后30眼(66.7%)，其中22眼(73.3%)视力>0.1。术后并发症：高眼压、玻璃体出血、视网膜脱离、并发性白内障、视神经萎缩、新生血管性青光眼、眼球萎缩。

结论：玻璃体视网膜手术是目前治疗晚期增殖性糖尿病视网膜病变的有效方法，正确掌握手术适应证，合理应用手术技术，及时准确地处理术后并发症，才能有效地改善晚期增殖性糖尿病视网膜病变患者视力。

METHODS: Totally 38 cases(45 eyes)with PDR stageⅥ operated with standard vitreoretinal surgery were analyzed retrospectively. Preoperative and postoperative visual acuity was studied. The complications of post-operation were analyzed.

RESULTS: Forty-five eyes were followed-up in the find examination. The vision of 0.05 or better was obtained from 14/45 eyes(31.1%)to 30/45 eyes(66.7%), in which, 22/30 eyes(73.3%)were 0.1 or better. The major operative complications included highintraocular pressure, vitreous hemorrhage, retinal detachment, complicated cataract, neovascular glaucoma, optic atrophy and ocular-atrophy.

CONCLUSION:Vitreoretinal surgery is an effective and safe procedure for the late stage of PDR to master surgical indications and techniques in order to obtain better visual improvement and reduce the surgical complications.
