倍频532nm激光治疗糖尿病性黄斑水肿

目的:观察激光治疗糖尿病性黄斑水肿(DME)的疗效。方法:回顾性分析DME患者45例(76眼),其中局限水肿44眼,弥漫性水肿32眼。对局限水肿行微血管瘤或扩张的毛细血管直接光凝,弥漫水肿行C形格栅或环形格栅光凝。主要指标依靠视力、眼底荧光素血管造影。结果:局限水肿中视力提高10眼(22.72%),不变25眼(56.82%),下降9眼(20.45%);弥漫水肿中视力提高10眼(31.25%),不变19眼(59.38%),下降3眼(9.38%)。局限水肿中水肿消退12眼(27.27%),减轻23眼(52.27%),未退9眼(20.45%)。弥漫水肿中水肿消退6眼(18.75%),减轻14眼(43.75%),未退12眼(38.71%)。结论:IRIS倍频532 nm激光治疗DME有效,局限性黄斑水肿比弥漫性黄斑水肿效果好。

IRIS532 overtone laser photocoagulation for diabetic macular edema

Objective:To investigate the effect of IRIS532 overtone laser photocoagulation treatment for diabetic macular edema.Methods: A retrospective study on 45 patients(76 eyes) were analyzed.Of them,44 eyes of localized edema were treated with direct photocoagulation and 32 eyes of diffuse edema were treated with grid photocoagulation.Vision and fundus fluorescein angiography were analyzed.Results: Among patients with localized edema,visual acuity was improved in 2 lines or more in 10 eyes(22.72%),not changed in 25 eyes(56.82%),and declined in 9 eyes(20.45%),and among patients with diffuse edema,these were respectively in 10 eyes(31.25%),19 eyes((59.38)%) and 3 eyes(9.38%).Among patients with localized edema,edema disappeared in 12 eyes(27.27%),alleviated in 23 eyes(52.27%) and did not changed in 9 eyes(20.45%),and among patients with diffuse edema,these were respectively in 6 eyes(18.75%),14 eyes(43.75%) and 12 eyes(38.71%).Conclusion: IRIS overtone 532nm laser photocoagulation is more effective for localized edema than for diffuse edema.
