玻璃体切割联合激光治疗增殖性糖尿病性视网膜病变

Treatment of POR by vitrectomy cornbined with laser

目的:观察分析玻璃体切割联合激光治疗增殖性糖尿病性视网膜病变的疗效及充填材料选择。方法:分析426例472眼增殖性糖尿病性视网膜病变的患者行玻璃体切割,膜剥离切除,眼内电凝,激光光凝并根据情况选用眼内充填材料。结果:术后随访6-12个月,448/472眼(占95%)一次视网膜解剖复位成功,除1眼术后合并中央静脉阻塞,1眼合并中央动脉阻塞,8眼视网膜脱离术后复发视力下降外,其余均有不同程度提高。视力0．05以上362眼(76．7%),与术前相比有显著性差异(P＞0．05),46眼视力大于0．2。结论:玻璃体切割手术联合激光治疗是挽救增殖性糖尿病性玻璃体视网膜病变患者最终失明的有效方法。

Objective：To explore the effect and the filling material of vitrectomy combining with laser on the treatment of PDR . Methods：426 cases 472 eyes of PDR treated with vitrectomy , membrane peeling,DOMS electric congulation ,laser photo- cogulation ,and the filling matreial of adoption acconding to condition .Result： The follow- up period was 6 months to 12 manths,448 eyes once succeed in the reattachment of retina, 1 eyes occured CRAO, 1 eye occurred CRVO. The sight of 8 eyes which re occurred the retinal separation dropped, the rest improved in some degrees. It became 0.05 or better in 362 eyes, 0.2 or better in 46 eyes. There was significant difference in visual acuity before and after operation （ P 〈 0.05）. Conclusion： Vitrectony combining with laser have the therapeutic effect for the patient with PDR.
