Objective To observe the clinical effects of vitrectomy in the treatment of patients with proliferative diabetic retinopathy (PDR). Methods One hundred and twelve patients with PDR (180 eyes) were randomly divided into the observation group (58 patients, 90 eyes) and the control group (54 patients, 90 eyes). The control group was treated with panretinal photocoagulation, and the observation group was treated with vitrectomy. Then the clinical effects were com-pared between the two groups. Results After the treatment, the improvement rates of visual acuity in the observation group (84.4%forⅣstage, 64.3%forⅤstage, 50.0%forⅥstage) were significantly higher than those of the control group (27.6%, 23.3%, 16.1%), with statistically significant differences (P<0.01). The incidence of secondary glaucoma of the ob-servation group was significantly lower than the control group (1.1%vs 14.4%, P<0.05), but the differences were not statisti-cally significant in the incidences of other complications between the two groups (P>0.05). Conclusion Vitrectomy has re-markable curative effect in the treatment of patients with PDR. It can effectively improve the patient's vision, reduce compli-cations, and improve the quality of life of patients, which is conducive to the postoperative recovery of patients and is wor-thy of promotion.%目的 探讨玻璃体切除术对增殖性糖尿病视网膜病变(PDR)患者的临床治疗疗效.方法 将112例PDR患者180只眼以数字表法随机分为观察组(58例,90眼)与对照组(54例,90眼),对照组给予光凝治疗,观察组给予玻璃体切除术治疗,比较两组患者的治疗效果.结果 治疗后观察组Ⅳ期好转率为84.4%,Ⅴ期好转率为64.3%,Ⅵ期好转率为50.0%,均明显高于对照组的27.6%、23.3%以及16.1%,差异均有统计学意义(P<0.05);观察组患者继发性青光眼发生率为1.1%,明显低于对照组的14.4%(P<0.05),其他并发症发生率比较则差异无统计学意义(P>0.05).结论 玻璃体切除术在PDR患者中具有确切的疗效,可有效改善患者视力,同时并发症较少,有利于患者术后恢复,且对于提高患者生活质量具有重要意义,值得临床推广.
