目的 探讨视网膜中央动脉阻塞 (central retinalartery occlusion,CRAO)患者眼底荧光血管造影 (fundusfluorescein angiography,FFA)的特征。方法 观察 2 6例 2 6眼 CRAO患者荧光片的眼底血管充盈情况。结果 CRAO患者 FFA示 :(1)动脉前期明显延长 ;(2 )视网膜动脉完成充盈循环时间延长 ;(3)视网膜动脉荧光素充盈前峰 ;(4)静脉回流迟缓 ;(5 )动脉小分支充盈缺损。结论 CRAO患者 FFA片上的主要特征为视网膜动脉充盈迟缓和 /或充盈不足。
Objective To investigate the characteristics of fundus fluorescein angiography (FFA) in patients with central retinal artery occlusion (CRAO). Methods Fourteen of 26 patients with 26 eyes of CRAO fluorescein fluorescein fundus filling. Results FFA in patients with CRAO showed: (1) pre-arterial prolongation; (2) prolongation of filling the retina artery filling cycle; (3) pre-fluorescein retinal artery filling peak; (4) delayed venous return; (5) Defect. Conclusion The main feature of FFA on-chip in patients with CRAO is delayed filling and / or under-filling of the retinal artery.
