【摘要】 目的 观察多波长氪激光治疗增殖期糖尿病视网膜病变的疗效。 方法 对52例74眼患有增殖期糖尿病视网膜病变伴有屈光间质混浊或轻度玻璃体积血的病例，进行了全视网膜光凝治疗。 结果 术前、术后视力的差异无显著性。全视网膜光凝治疗后视盘和视网膜的新生血管部分消退。 结论 多波长氪激光以不同波长为特点，对伴有屈光间质混浊或轻度玻璃体积血的增殖期糖尿病视网膜病变，进行全视网膜光凝术是有效的治疗方法，可使新生血管消退，有效地阻止了增殖期糖尿病视网膜病变的发展，防止再出血的发生。

    【Abstract】 Objective To observe the effects of multi-wavelength krypton laser treatment for proliferative dia-betic retinopathy(PDR).Methods 52cases(74eyes)of PDR with refractive media opacity or mild vitreous hemor-rhage were treated with panretinal photocoagulation.Results In preoperation and postoperation，visual acuity was not different significantly.Neovascularization of the disc/retina partly regressed after the panretinal photocoagulation.Con-clusion Multi-wavelength krypton laser is effective to abate neovascularization and prevents the recurrence of hemor-rhage ......
