氩绿激光治疗糖尿病性黄斑水肿的临床观察

Clinical observation on argon green laser in the treatment of diabetic macular edema

目的 :评价氩绿激光治疗糖尿病性黄斑水肿的临床效果。方法 :采用波长为 5 14nm的氩绿激光对黄斑水肿患者 19人 2 3眼进行格栅样光凝治疗 ,光斑直径 10 0～ 2 0 0 μm ,曝光时间 0 .1～ 0 .2s,能量 10 0～ 30 0mW。周边视网膜光凝均在黄斑光凝完成后进行。平均随访 (9.3± 4 .1)个月 ,期间观察治疗前后黄斑水肿消退及视力变化的情况。结果 :2 3眼中 2 1眼黄斑水肿完全或部分消退 ;19眼视力得以保持或改善。结论

Objective To assess the clinical effect of argon green laser photocoagulation on diabetic macular edema. Methods Grid macular photocoagulation with argon green laser (λ= 514 nm), 100～200 μm spot diameter and 0.1～0.2 s duration, was applied to 23 eyes of diabetic macular edema. Panretinal scatter photocoagulations, if needed, were carried out in the later therapy. The mean of the follow up period was (9.3±4.1) months. Changes in macular edema and visual acuity as well were observed. Results Complete and partial resolution of macular edema occurred in 21 out of the 23 eyes and visual acuity improved or remained unchanged in 19 out of the 23 eyes. Conclusion Grid macular photocoagulation with argon green laser is effective and relatively safe in the treatment of diabetic macular edema.
