摘　　要：目的 探讨各类导致视网膜毛细血管扩张疾病的临床特征.方法 对2008～2012年在云南红十字会医院眼科经回顾分析特发性黄斑旁毛细血管扩张症、Coat＇s病、视网膜分支静脉阻塞、糖尿病视网膜病变、视网膜血管炎患者计69例（112只眼）的临床资料、眼底彩照、眼底荧光血管造影等进行总结分析.结果 5例特发性黄斑旁毛细血管扩张症表现为黄斑区灰白色病灶,黄斑毛细血管网扩张,渗漏;6例Coat＇s病患者表现为大片视网膜渗出,视网膜血管瘤样扩张;18例视网膜分支静脉阻塞患者表现为沿阻塞区域分布的毛细血管扩张,缺血型可见无灌注区;21例糖尿病视网膜病变者表现为广泛散在的视网膜毛细血管扩张、微动脉瘤形成,合并出血渗漏病变;19例视网膜血管炎典型表现除视网膜血管扩张外,血管壁染色、渗漏.结论 特发性、缺氧、炎症、血流动力学改变、放射性损伤等,均可破坏血管内皮细胞或周细胞,从而表现为毛细血管扩张,结合患者资料、全面分析判断视网膜毛细血管扩张的原因及对策.Objective To explore the characteristics of fundus photography and fundusfluorescein angiography in patients of retinal telangiectasis.Methods Retrospective analysis of idiopathic macular telangiectasia,Coat＇s disease,retinal Branch vein occlusion,diabetic retinopathy,retinal vasculitis,the clinical data were summarized.Results Five cases of idiopathic paramacular telangiectasia showed white lesions,macular capillary network expanded and leakage; 6 cases of Coat＇s disease showed a large retinal exudation,retinal vascular ectasia; 18 cases of patients with branch retinal vein occlusion showed regional telangiectasia along the blocking vein,no-perfusion areas can be seen in the ischemic area; 21 cases of diabetic retinopathy showed widely scattered retinal telangiectasia,micro aneurysm formation,hemorrhage leakage lesions; 19 cases of retinal vasculitis showed dilated retinal veins,the blood vessel walls stained and leakage.Conclusions Idiopathic,hypoxia,inflammation,hemodynamic changes,and radiation damage can damage endothelial cells or pericytes,which manifest as telangiectasia,comprehensive analysis and determine the causes and measurements.
