摘　　要：目的评价氪黄激光治疗糖尿病性黄斑水肿的疗效。方法糖尿病视网膜病变合并黄斑水肿患者65例107眼,其中局限性黄斑水肿39眼,弥漫性黄斑水肿45眼,囊样黄斑水肿23眼,采用波长为568nm的氪黄激光进行光凝治疗。对局限性黄斑水肿,以激光直接封闭微血管病和无灌注区,光斑直径50～200μm,照射时间0.2s,功率200～300mW;对弥漫性黄斑水肿和囊样黄斑水肿,行格栅样光凝,光斑直径100～200μm,照射时间0.1s,功率250～400mW。观察治疗前后患者视力及黄斑水肿的变化。结果视力提高2行以上24眼(22.43%),视力稳定65眼(60.75%),视力下降18眼(16.82%)。治疗后局限性黄斑水肿患者视力的提高较弥漫性黄斑水肿患者和囊样黄斑水肿患者显著。局限性黄斑水肿组水肿完全吸收17眼(43.59%),弥漫性黄斑水肿组为16眼(35.56%),囊样黄斑水肿组为1眼(4.35%),P=0.000。结论氪黄激光治疗糖尿病性黄斑水肿是安全有效的方法,且早期治疗疗效好。Objective To assess the therapeutic effects of krypton yellow laser for diabetic macular edema. Methods A total of 107 eyes of 65 patients with diabetic macular edema were grouped into focal macular edema, diffuse macular edema and cystoid macular edema and treated by krypton yellow laser. Results The vision of 24 eyes improved two lines or better ,unchanged in 65 eyes. After photocoagulations, 17 eyes of focal macular edema, 16 eyes in diffuse macular edema, and 1 eye in cystoid edema were absorbed totally. Conclusions Krypton yellow laser for diabetic macular edema may be a safe and effective method to treat diabetic macular edema.
