目的 :分析玻璃体切除术治疗严重增殖型糖尿病视网膜病变 (PDR)的疗效。 方法 :PDR患者 31例 (35眼 ) ,在控制血糖、血压情况下行玻璃体切除术 ,术中均作次全或全视网膜光凝。分析手术前后及随访 6～ 32个月的资料。结果 :最后随访时 ,视网膜平伏 ,眼底清晰可见 ,保留一定视力的手术成功眼为 2 9眼 ,最后成功率为 82 .9% ;病变较轻组比病变重度组成功率高 (P<0 .0 5 ) ;出血时间 >6个月组较出血时间≤ 6个月组成功率低 (P<0 .0 5 )。手术成功眼最后视力有明显提高 ,6 2 .9%达0 .1以上 ,2 8.6 %达 0 .4以上。 结论 :适时进行玻璃体切除术联合视网膜光凝治疗严重 PDR有较好疗效
Objective: To analyze the curative effect of vitrectomy on severe proliferative diabetic retinopathy (PDR). Methods: Thirty-one patients (35 eyes) with PDR underwent vitrectomy under control of blood glucose and blood pressure. All patients underwent total or full retinal photocoagulation during and after operation. Before and after surgery and follow-up of 6 to 32 months of data. Results: At the final follow-up, the retina was flat and the fundus was clearly visible. The successful eyes with a certain visual acuity were 29 eyes and the final success rate was 82.9%. The severity of lesion was higher than that of the lesion (P <0. 0 5). The bleeding time> 6 months was lower than that of the bleeding time ≤ 6 months (P <0.05). The final visual acuity was significantly improved in the successful eye surgery, with 62.9% reaching over 0.1% and 8.6% reaching over 0.4. Conclusion: Timely vitrectomy combined with retinal photocoagulation for the treatment of severe PDR has a good effect
