205例Coats病临床分析

目的分析总结Coats病患者的一般临床规律和眼底特征。方法回顾分析205例Coats病患者211只眼的临床资料，统计分析患者性别、年龄、眼别及视力分布情况；根据检眼镜以及荧光素眼底血管造影(FFA)检查所见的眼底及FFA特征，分析病变部位、范围及病变程度，探究病变分布及发展规律。结果 205例患者就诊时平均年龄28.0岁，20岁以上占54.2%。其中，男性占76.1%；单眼发病占97.1%。211眼中，视力0.3及其以下者占67.3%。所有患者均有眼底微血管异常扩张，90.5%伴有黄白色脂质渗出；异常扩张血管90.1%位于颞侧，73.9%位于赤道以前，72.5%波及1个以上象限。结论 Coats病多发于男性，各年龄段均可发病，几乎均为单眼发病。最本质特征是微血管异常扩张，绝大部分位于颞侧赤道前的视网膜，通常伴有黄白色脂质渗出并波及黄斑，对视功能损害严重。 （中华眼底病杂志，2008，24：276-278）

Clinical Analysis of 205 Coats Disease

Objective To analyze and summarize the clinical regulation and ocular fundus characteristics of the Coats diseases paients. Methods The clinical data of 205 Coats diseases (211 eyes) which including sex, age, which-eye and visual distribution were retrospectively analyzed. To analyze the region, scope, and degree of the disease according to the ophthalmoscopy, ocular fundus photography, and fundus fluorescein angiography results, in additon to invistigate the distribution and development rule of lesions. Results In 205 cases, Coats disease was diagnosed at a median age of 28 years old. There were 54.2 % patients over 20 years old. It occurred in 76. 1% males,and was unilateral in 97.1% patients. In 211 eyes, the visual acuity was below 0.3 in 67.3% eyes. The retinal telangiectasia occurred in all eyes, with yellow white lipid exudation in 90.5% eyes; located in temporal fundus in 90.1% eyes, in front of midperipheral 73.9% eyes; spread over one sector in 72. 5% eyes. Conclusions Coats disease occurs mostly in males; it can occurrs in any age; it almost occurrs in unilateral. The essential characteritics are abnormal expansion of microvascular, mostly located in temporal fundus and in front of midperipheral, with yellow white lipid exudation, spread macular and damage visual function seriously.
