【摘要】目的:观察氩激光治疗中心性浆液性脉络膜视网膜病变的疗效。方法:根据视网膜血管荧光造影确诊,确定渗漏点的位置,采用氩激光直接封闭渗漏点。结果:56例(56眼),光凝一次治愈49眼,两次激光治愈7眼。其中1wk治愈7眼,2wk治愈14眼,3wk治愈12眼,4wk治愈10眼。>4wk~2mo以上治愈13眼。6眼复发,再次激光治疗治愈。结论:氩激光治疗中心性浆液性视网膜病变病程明显缩短,视力提高,无并发症的发生。

AbstractAIM: To observe the clinical efficacy of argon laser treatment for central serous chorioretinopathy.METHODS: The location of leak spot was defined by fluorescein retina angiography and was blocked by argon laser directly.RESULTS: In 56 cases (56 eyes), 49 eyes were cured by photocoagulation once, 7 eyes by twice, in which, 7 eyes were cured in 1 week, 14 eyes in 2 weeks, 12 eyes in 3 weeks, 10 eyes in 4 weeks, 13 eyes above 4 weeks~2 months. Six eyes recurred and were cured with laser therapy again. CONCLUSION: Argon laser treating central serous chorioretinopathy can shorten course significantly, improve visual acuity and has no complications. KEYWORDS: argon laser; central serous chorioretinopathy
0引言
中心性浆液性视网膜病变的原发位置是在视网膜色素上皮。正常情况下,视网膜色素上皮具有屏障作用。脉络膜毛细血管的渗液不能通过视网膜色素上皮进入视网膜下。如果视网膜色素上皮出现局限性的损害,它的屏障作用受到破坏,渗液便通过破损的色素上皮进入视网膜下腔,并在该处积存,使视网膜向前隆起,形成视网膜神经上皮脱离。因此而出现了中心性浆液性视网膜脉络膜病变(central serous chorioletinopathy,CSC,简称“中浆”)的症状和体征,眼底荧光血管造影可见荧光素渗漏点。以往采取微血管扩张药物静脉注射,病程长复发率高,我院在200601/200701采用氩激光治疗56例(56眼)中心性浆液性视网膜病变[1,2],取得良好效果,报告如下。
1对象和方法
1.1对象
我院应用氩离子激光治疗中心性浆液性视网膜病变56例(56眼)。其中男43例(43眼),女13例(13眼)。年龄24~55(平均37.2)岁。发病时间最短1wk,最长1mo。眼底荧光血管造影显示渗漏点位于视乳头黄斑纤维束内,或在黄斑中心凹无血管区250μm以内者,排除在外。
1.2方法
56眼常规眼底荧光血管造影检查,有3个渗漏点11眼,2个渗漏点16眼,1个渗漏点29眼。治疗采用氩激光直接照射渗漏点,所用激光参数:功率0.05~0。1W,光斑直径50~l00μm,曝光时间0.05~0.1s。每个渗漏点照射2~6光凝点,出现淡灰白色I级反应。光凝15d后病情无改善者,给予第2次治疗。
