目的探讨白内障手术与玻璃体切除手术联合治疗增生性糖尿病视网膜病变（PDR VVI期）患者的临床效果。方法选取2012年1月至2014年1月80例增生性糖尿病视网膜病变患者作为研究对象，按手术方法分成单一术组和联合术组。单一术组患者仅进行玻璃体切除手术，联合术组患者联合白内障手术与玻璃体切除手术治疗。比较2组患者在视网膜复位率、视力水平和术后并发症等情况。结果联合术组患者和单一术组患者相比，视网膜复位率明显较高，组间比较差异有显著的统计学意义（P＜0.05）。联合术组患者视力水平改善幅度高于单一术组，组间比较差异有统计学意义（P＜0.05）。联合术组患者手术并发症少于单一术组，组间比较差异有统计学意义（P＜0.05）。结论白内障手术联合玻璃体切除手术治疗增生性糖尿病视网膜病变临床效果确切，可有效提高视网膜复位率和视力水平，减少并发症发生率，安全可靠。
Objective To investigate the clinical effect of cataract surgery combined with vitrectomy in the treatment of proliferative diabetic retinopathy (PDR VVI stage). Methods Eighty patients with proliferative diabetic retinopathy from January 2012 to January 2014 were selected as study subjects and divided into single surgery group and combined surgery group according to surgical methods. Patients in the monotherapy group were treated with vitrectomy only, and patients in the combined surgery group were treated with cataract surgery and vitrectomy. The retinal reattachment rate, visual acuity and postoperative complications were compared between the two groups. Results The retinal reattachment rate was significantly higher in the combined surgery group than in the single surgery group, with significant differences between the two groups (P <0.05). The improvement rate of visual acuity in the combined surgery group was higher than that in the single surgery group, the difference was statistically significant (P <0.05). The surgical complications in the combined surgery group were less than those in the single surgery group, the difference was statistically significant (P <0.05). Conclusions Cataract surgery combined with vitrectomy for the treatment of proliferative diabetic retinopathy has definite clinical effect, which can effectively improve the retinal reattachment rate and visual acuity, reduce the incidence of complications and be safe and reliable.
