目的：探讨合并玻璃体积血的增殖性糖尿病视网膜病变(proliferative diabetic retinopathy，PDR)的手术干预时机。
方法：采用回顾性的研究方法对128例177眼合并玻璃体积血的PDR患者的手术疗效进行对比观察。PDR患者依据疾病进程分为Ⅳ级组、Ⅴ级组以及Ⅵ级组。采用玻璃体切除术以及眼内视网膜激光对各组患者进行治疗，观察并比较三组患者手术并发症、前房炎症反应、术后1wk眼压以及术后6mo视力恢复情况。
结果：与术前相比，所有患者视力均恢复，但三组中以Ⅳ组视力恢复最为显著(P<0.05)； 三组患者手术相关并发症发生率、前房炎症以及术后平均眼压，均未发现统计学差异(P>0.05)。
结论：在Ⅳ级时对PDR患者进行手术干预可在不增加手术风险的同时显著提高疗效。

AIM: To explore the surgical intervention time in treatment of proliferative diabetic retinopathy(PDR)combined with vitreous hemorrhage.
METHODS: Totally, 128 cases(177 eyes)with PDR combined with vitreous hemorrhage were investigated retrospectively. Patients with PDR were divided into Ⅳ group, Ⅴ group and Ⅵ group. Vitrectomy and laser treatment were applied. Surgical complications, anterior chamber inflammation, intraocular pressure 1 week after surgeries and restoration of vision 6 months after surgeries were observed and compared between groups.
RESULTS:Vision of all patients restored significantly after surgeries, but more significantly in Ⅳ group(P<0.05); there were no significant differences of surgical complications, anterior chamber inflammation and intraocular pressure 1 week after surgeries in 3 groups(P>0.05).
CONCLUSION: Clinical effects could be improved significantly by surgical intervention at Ⅳ stage of PDR without increasing any surgical risks.
