Frequency multiplier semiconductor laser(532nm)treats macular edema caused by blood vessel diseases of retina

目的:探讨倍频半导体激光(5 32nm)治疗视网膜血管病所致黄斑水肿的疗效。方法:对78例、10 8眼视网膜血管病所致黄斑水肿患者施行5 32nm纯绿半导体激光治疗,其中局限性水肿用局灶性光凝,弥漫性黄斑水肿及囊样黄斑水肿用格栅样光凝。术后随访3～18个月,平均10 .5个月,对比治疗前后视力及黄斑水肿的变化。结果:黄斑局限性水肿15眼,视力提高或无变化14眼(92 .3% ) ,视力下降1眼(6 .7% ) ;水肿全部或部分吸收14眼(92 .3% ) ,未吸收1眼(6 .7% )。弥漫性水肿4 1眼,视力提高或无变化35眼(85 .4 % ) ,视力下降6眼(14 .6 % ) ;水肿全部或部分吸收33眼(80 .5 % ) ,未吸收6眼(14 .6 % ) ,加重2眼(4.9% )。黄斑囊样水肿5 2眼,视力提高或无变化4 3眼(82 .7% ) ,视力下降9眼(17.3% ) ;水肿全部或部分吸收38眼(78.9% ) ,未吸收9眼(17.3% ) ,加重2眼(3.8% )。结论:倍频半导体激光治疗视网膜血管病所致黄斑水肿安全且疗效显著。

Objective:To search for the curative effect of frequency multiplier semiconductor(532nm) in treating macular edema caused by retinal blood vessel diseases.Methods::One hundred and eight eyes of 78 cases were performed by pure green semiconductor laser, including local laser solidification,and grid laser solidification to general macular edema and cystoid macular edma. Followed up from 3 to 18 months, with an average of 10.5 months,the eyesight and the change of macular edema before and after treatment were compared.Results:Among the 15 eyes with limit macular edma, eyesight of 14 eyes was improved or not changed(92.3%), of 1 eye dropped (6.7%); the edema of 14 eyes was completely or partly absorbed(92.3%),of 1 eye was not absorbed(6.7%). Among 41 eyes with general edema, eyesight of 35 eyes was improved or not changed(85.4%), of 6 eyes dropped(14.6%); the edema of 33 eyes was completely or partly absorbed(80.5%), of 6 eyes was not absorbed(14.6%),of 2 eyes became even worse(4.9%). Among 52 eyes of cystoid macular edema, eyesight of 43 eyes was improved or not changed (82.7%), of 9 eyes dropped (17.3%); the edema of 38 eyes was completely or partly absorbed (78.9%), of 9 eyes was not absorbed (17.3%), of 2 eyes became even worse (3.8%).Conclusion:Frequency multiplier semiconductor laser(532nm)for macular edema caused by retinal blood vessel diseases has high safety and obvious curative effect.
