【摘要】 目的比较氪绿激光、氪黄激光和氪红激光治疗增殖期糖尿病性视网膜病变(PDR)的疗效。方法 PDR患者167例243只眼,随机分为氪绿激光、氪黄激光和氪红激光治疗组,行标准全视网膜光凝。比较三组患眼视力、新生血管的变化。结果三组患者视力比较差异无显著意义(P>0.05)。新生血管消退比较,氪绿激光组与氪红激光组比较差异无显著意义(P>0.05)。氪黄激光组与氪绿激光组、氪红激光组比较差异有显著意义(P<0.05)。结论氪绿激光、氪黄激光和氪红激光对PDR均有治疗作用,氪绿激光和氪红激光的疗效较好。更多还原

【Abstract】 Objective To investigate the therapeutic effect of the krypton green,krypton yellow or krypton red laser in the treatment of proliferative diabetic retinopathy(PDR). Methods Two hundred and forty-three eyes of 167 PDR patients were assigned randomly to receive either krypton green,krypton yellow or krypton red laser treatment,to investigate the changes in the vision and neovessels. Results There was no statistical difference among krypton green,krypton yellow and krypton red laser treatment for PDR(P>0.05) in visual improvement,and also between krypton green with krypton red laser in neovessels loss,but there was statistical difference between krypton yellow with krypton green or krypton red laser in it. Conclusions The three kinds of krypton lasers all have therapeutic effect on PDR,but the krypton green and krypton red lasers should be preferred.更多还原
