视网膜大动脉瘤临床分析

目的观察视网膜大动脉瘤的临床特征和荧光素眼底血管造影及吲哚菁绿血管造影（FFA、ICGA）及相干光断层扫描（OCT）的图像特征，提高其诊断准确性。方法对14例诊断为视网膜大动脉瘤患者的临床资料和FFA、ICGA及OCT等检查结果进行回顾性分析。结果14例患者中男性5例，女性9例。年龄57～82岁，平均71岁。多数患者伴有高血压、糖尿病等病史。均为单眼发病，单个大动脉瘤瘤体均位于视网膜颞侧动脉分支，其中颞上支动脉10例，颞下支动脉4例；动脉瘤都位于2—3级分支内。瘤体呈灰黄色或红色，周围有不同程度的视网膜出血和环形或弧形渗出。FFA和ICGA检查显示动脉瘤呈圆点状强荧光，晚期有不同程度的荧光渗漏和瘤体壁染，出血呈遮蔽荧光。OCT图像显示视网膜出血使视网膜隆起，视网膜内呈现高反射，出血为暗区，遮挡下方组织反射，水肿呈低反射；可伴有视网膜神经上皮的出血性和（或）浆液性脱离，呈现低反射。结论FFA和ICGA检查有助于视网膜大动脉瘤的早期正确诊断；应掌握视网膜大动脉瘤的临床特征和FFA、ICGA及OCT的图像特征，注意与渗出型年龄相关性黄斑变性（AMD）、成人型Coats病等眼病相鉴别。
