摘　　要：目的观察视网膜大动脉瘤的临床特征。方法回顾性分析10例(10只眼)视网膜大动脉瘤的l临床资料、眼底荧光血管造影(FFA)和吲哚青绿血管造影(ICGA)结果。结果10例患者中,6例通过眼底检查和FFA即可明确诊断,FFA表现为视网膜大动脉瘤处的局部性强荧光,周围有出血者则有遮蔽荧光环绕,4例FFA表现为视网膜出血遮挡荧光,瘤体显示不清,通过ICGA可见视网膜大动脉上一局灶性的强荧光。其中1例有玻璃体出血。结论视网膜大动脉瘤是视网膜动脉的病理性扩张,FFA检查对视网膜大动脉瘤的诊断和鉴别诊断有重要意义。如视网膜出血较多时,FFA可能难以发现病灶,ICGA能清楚显示视网膜大动脉病损和动脉壁相连,有助于明确诊断。有些视网膜大动脉瘤患者未治疗视力预后亦好,如果视网膜大动脉瘤出血累及黄斑,或导致玻璃体出血,视功能会受到严重损害,应及早光凝治疗。Objective To describe the chnical features of patients with retinal macroaneurysm. Method Restrospective studies the clinical features and FFA and ICGA of 10 eyes with retinal macroaneurysms in 10 patients. Result In 10 case, 6 case were identifiable by funds examination and FFA. FFA showed local hyperfluorescein in retinal macroaneurysm and round blocked-fluorescein corresponding to the hemorrhage around the macroaneurysm The retinal macroaneurysms were obscure because of dense retinal hemorrage. ICGA showed a local hyperfluorescence which corresponded to the macroaneurysm of the branch artery. Conclusion The retinal macroaneurysm is pathological distension of the retinal artery. FFA is important for the diagnosis and differential diagnosis. If the lesion cant be identified by FFA because of dense dense hemorrhage. ICGA can show clearly the lesion . It is helpful for the correct diagnosis. Some retinal macroaneurysm do not require the treatment , and others need early laser treatment.
