Therapeutic Effect of Krypton Yellow Laser in Treating Diabetic Macular Edema

目的观察氪黄激光治疗糖尿病黄斑水肿的疗效。方法2007年3月至2007年12月经眼底荧光造影检查确诊为糖尿病视网膜病变Ⅳ期并伴有黄斑水肿,接受氩激光全视网膜光凝联合黄斑区氪黄激光栅格样光凝治疗的2型糖尿病患者63例75只眼,分析术后1、3和6个月的视力和眼底荧光造影的变化。结果术后1个月,视力提高20只眼(26.7%),视力稳定27只眼(36.0%),视力下降28只眼(37.3%);眼底荧光造影检查无明显渗漏11只眼(14.7%),渗漏缩小37只眼(49.3%),渗漏无明显变化27只眼(36.0%)。术后3个月,视力提高31只眼(41.3%),视力稳定28只眼(37.3%),视力下降16只眼(21.3%);眼底荧光造影检查无明显渗漏33只眼(44.0%),渗漏缩小28只眼(37.3%),渗漏无明显变化14只眼(18.7%)。术后6个月,视力提高43只眼(57.3%),稳定24只眼(32.0%),视力下降8只眼(10.7%);眼底荧光造影检查无明显渗漏57只眼(76.0%),渗漏缩小11只眼(14.7%),渗漏无明显变化7只眼(9.3%)。结论氪黄激光栅格样光凝治疗糖尿病黄斑水肿疗效显著。

Objective To evaluate the therapeutic effect of krypton yellow laser in treating diabetic macular edema. Methods Sixty-three patients （75 eyes ） , were with stage Ⅳ diabetic retinopathy and macular edema and examined by fundus fluorescein angiography（FFA） the change in vision and FFA was analyzed at 1,3 and 6 months after therapy. Results At 1 month after therapy , the vision was improved in 20 （26.7%） eyes , remained in 27 （36. 0% ） eyes and decreased in 28 （ 37.3% ） eyes. The FFA showed the ]eakage stop in 11 （ 14. 7% ） eyes, reduced in 37 （49. 3% ） eyes and remained in 27 （ 36. 0% ） eyes; at 3 months after therapy, the vision was improved in 31 （41.3%） eyes, remained in 28 （37.3%） eyes and decreased in 16 （21.3%） eyes. The FFA showed the leakage stop in 33 （44. 0% ） eyes, reduced in 28 （37. 3% ） eyes and remained in 14 （ 18.7% ） eyes ; at 6 months after therapy, the vision was improved in 43 （ 57.3% ） eyes, remained in 24 （ 32.0% ） eyes and decreased in 8 （ 10. 7% ） eyes. The FFA showed the leakage stop in 57 （76. 0% ） eyes, reduced in 11 （ 14.7% ） eyes and remained in 7 （9. 3% ） eyes and. Conclusions The krypton yellow laser is efficient to treat diabetic macular edema.
