本文报告一例视网膜分支动脉阻塞（BRAO）的荧光素血管造影（FA）和新型光学相干地形图血管造影（OCTA）。OCTA显示出继发于视网膜动脉栓塞的界限分明的血流中断区域，以及与FA结果相对应的受累区域中的毛细血管无灌注。因此，OCTA可以显示与FA结果相关的栓塞性BRAO的血管特征。在这种情况下，OCTA还显示了在FA上未观察到的浅表血管毛细血管丛中的灌注缺损增加。
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.
