A case of embolic branch retinal artery occlusion (BRAO) was evaluated utilizing both fluorescein angiography (FA) and novel optical coherence topography angiography (OCTA). OCTA demonstrated a well-demarcated area of flow interruption secondary to the retinal artery embolus, as well as capillary nonperfusion in the involved region corresponding to FA findings. Therefore, OCTA can demonstrate vascular features of embolic BRAO correlating to FA findings. In this case, OCTA also revealed an increased perfusion defect in the superficial vascular capillary plexus that was not seen on FA.
利用荧光素血管造影（FA）和新型光学相干断层扫描血管造影（OCTA）对一例视网膜动脉分支栓塞性阻塞（BRAO）病例进行了评估。OCTA显示继发于视网膜动脉栓子的血流中断区域界限清晰，以及与FA结果相对应的受累区域的毛细血管无灌注。因此，OCTA可以显示与FA结果相关的栓塞性BRAO的血管特征。在该病例中，OCTA还显示在FA上未见的浅表血管毛细血管丛灌注缺损增加。
