【摘要】 目的　探讨糖尿病黄斑病变荧光素眼底血管造影检查特征及诊断分型标准。方法　应用荧光素眼底血管造影进行诊断分型。结果　 (1)诊断分型 :凡视网膜病变距黄斑中心凹 1PD以内或累及到 1PD范围以内者均称为黄斑病变。根据荧光素眼底血管造影检查分为缺血性黄斑病变 (黄斑区有局限性毛细血管闭塞的无灌注区形成 ,有或无黄斑拱环扩大或断裂 )和黄斑水肿两大类。黄斑水肿又分为囊样水肿 (眼底造影晚期形成花瓣样荧光素贮存 )和非囊样水肿 ;根据其病变渗漏范围小于 2个象限的为局部水肿 ,大于 2个象限者为弥漫水肿。 (2 )分型结果 :本组 12 7例 (2 11眼 )中 ,缺血性病变 5眼 ,占 2 .4% ;囊样水肿 2 0眼 ,占 9.5 % ;局部水肿 12 6眼 ,占 5 9.7% ;弥漫水肿 6 0眼 ,占 2 8.4%。结论　糖尿病黄斑病变应用荧光素眼底血管造影诊断分型 ,敏感可靠 ,易于推行 ,建议制订我国对本病的诊断标准 ,并与我国现行的糖尿病视网膜病变分期标准结合应用 ,更能准确的描述其眼底病变 ,并指导临床治疗。更多还原

【Abstract】 Objective To investigate the characteristics of fundus fluorescence angiography(FFA) and diagnostic classification criterion of diabetic maculopathy.Methods Diagnostic classification were made through FFA.Result (1)Diagnostic classification:retinopathy that is equal or less to 1PD around macular central fovea is defined as maculopathy.Maculopathy includes ischmic maculopathy (limited nonirrigation zone with or without macular arch ring enlargement and break) and macular edema.Macular edema contains cystoid edema (flower-like fluorescence reservoir at late tage of FFA) and noncystoid macular edema.Exudution range<2PD is defined as local edema,>2PD is diffuse edema.(2)Classification result:In 211 eyes of 127 cases,5 eyes of ischemic maculopathy were 2.4%;20 eyes of cystoid edema 9.5%;126 eyes of local edema 59.7%;60 eyes of diffuse edema 28.4%.Conclusion Diabetic maculopathy classification according to FFA is sensitive and reliable and available to be introduced.We suggest that diagnostic criterion of the desease will be made being combined with current diabetic retinopathy classification.that criterion will describe fundus disease more accurately and direct theraphy更多还原
