Abstract：
BACKGROUND: The most common complication after vitrectomy is the rebleeding in vitreous cavity. It is important to detect the different factors that can increase the vitreous rebleeding rate in these patients.
OBJECTIVE: To carry out a retrospective review of the rate of vitreous rebleeding after vitrectomy or phacovitrectomy.
METHODS: Retrospective, descriptive and comparative study of patients with a diagnosis of proliferative diabetic retinopathy with phacovitrectomy or vitrectomy procedure. Personal background data, type of surgical intervention and grade of the surgeon who carried out the procedure were obtained.
RESULTS: 1227 files of diabetic patients with vitrectomy or phacovitrectomy were reviewed. 65% presented systemic arterial hypertension. The average glomerular filtration rate was 63.50 (±32.36) ml/min/1.73 m2 and glycosylated hemoglobin (HBA1C) of 8% (4.6 to 15%). In the comparison of variables, a significant difference in the rate of vitreous rebleeding was obtained comparing phacovitrectomy with vitrectomy. (p = 0.003), in the relationship between vitrectomy with vitreous rebleeding, an odds ratio of 1.44 was obtained.
CONCLUSIONS: The results obtained show a lower rate of rebleeding in patients undergoing phacovitrectomy in patients with proliferative diabetic retinopathy.

摘要：
背景：玻璃体切除术后最常见的并发症是玻璃体腔再出血。重要的是检测可以增加这些患者玻璃体再出血率的不同因素。
目的：对玻璃体切除术或晶状体切除术后玻璃体再出血的发生率进行回顾性分析。
方法：回顾性，对诊断为增殖性糖尿病视网膜病变的患者进行超声玻璃体切除术或玻璃体切除术的描述性和比较研究。个人背景资料,获得了手术干预的类型和进行手术的外科医生的等级。
结果：回顾了1227份糖尿病患者的玻璃体切除术或超声玻璃体切除术。65%表现为全身动脉高血压。平均肾小球滤过率为63.50(±32.36)ml/min/1.73m2,糖化血红蛋白(HBA1C)为8%(4.6～15%)。在变量的比较中，玻璃体切除术与玻璃体切除术相比,玻璃体再出血的发生率有显著差异.（p=0.003），在玻璃体切除术与玻璃体再出血之间的关系中，得到的比值比为1.44。
结论：所获得的结果表明，在患有增生性糖尿病视网膜病变的患者中，接受玻璃体切除术的患者的再出血率较低。
