激光光凝治疗糖尿病性黄斑水肿的临床观察

Clinical observation of the efficacy of laser photoeoagulation for the treatment of diabetic macular edema

目的观察激光光凝治疗糖尿病性黄斑水肿(DME)的疗效。方法对50只眼局限性DME和36只眼弥漫性DME分别进行局灶光凝和格栅光凝治疗。结果局限性DME组光凝后视力提高18只眼(36%),无变化24只眼(48%),视力下降8只眼(16%),弥漫性DME组光凝后视力提高6只眼(17%),无变化25只眼(69%),视力下降5只眼(14%)。两组对比P<0.05,有显著性差异。结论激光光凝治疗DME安全、有效,局限性DME比弥漫性DME效果好。

Objective To observe the therapeutic effect of laser photocoagulation on diabetic macular edema （ DME ）. Methods 50 eyes with localized edema were treated by local photocoagulation,36 eyes with diffuse edema were treated by grid photocoagulation. Results Among patients with localized edema, the postoperative visual acuity improved in 18 eyes（36% ） ,remained unchanged in 24 eyes（ 48% ） ,and worsened in 8 eyes（ 16% ） .Among patients with diffuse edema, the postoperative visual acuity improved in 6 eyes（17% ） ,remained unchanged in 25 eyes（ 69% ） ,and wors- ened in 5 eyes（ 14 % ） . Conclusion Laser photocoagulation treatment for diabetic macular edema is effective. It is found that therapeutic response is better in localized edema than that in diffuse edema.
