目的：分析23G玻璃体切割术治疗增生型糖尿病视网膜病变(PDR)术后早期发生出血的危险因素。

方法：回顾性分析2016-06/2018-01于我院行23G玻璃体切割术治疗的PDR患者100例100眼的临床资料，根据术后早期(1mo内)是否发生玻璃体出血分为早期玻璃体出血组(27例)和无玻璃体出血组(73例)，分析术后早期发生玻璃体出血的危险因素。

结果：两组患者年龄、术前抗VEGF治疗、术前存在纤维血管膜增殖、术中视盘新生血管出血、术中注入气体情况有明显差异(P<0.01)，其中术前存在纤维血管膜增殖、术中存在视盘新生血管出血是导致术后早期出血的独立危险因素。

结论：23G玻璃体切割术治疗PDR术后早期玻璃体出血主要发生于眼底病变严重者，术前存在纤维血管膜增殖及术中视盘新生血管出血会增加其发生风险。

METHODS: A retrospective analysis was made on the clinical data of 100(100 eyes)PDR patients who were underwent 23G vitrectomy from June 2016 to January 2018. According to whether vitreous hemorrhage occurred in the early stage of operation(within 1mo), the patients were divided into early vitreous hemorrhage group(27 cases)and non vitreous hemorrhage group(73 cases). The risk factors of early vitreous hemorrhage were analyzed.

RESULTS: There were significant differences in age, preoperative anti-vascular therapy, preoperative fibrovascular membrane proliferation, intraoperative optic disc neovascularization hemorrhage and intraoperative gas injection between the two groups(P<0.01). Preoperative fibrovascular membrane proliferation and intraoperative optic disc neovascularization hemorrhage were independent risk factors for early postoperative hemorrhage.

CONCLUSION: Early vitreous hemorrhage after 23G vitrectomy for PDR mainly occurs in patients with severe fundus lesions. Preoperative fibrovascular membrane proliferation and intraoperative optic disc neovascularization hemorrhage increase the risk of vitreous hemorrhage.
