PURPOSE
We report the variability in flow angiogram during the course of branch retinal artery occlusion (BRAO) in a case imaged by optical coherence tomography angiography (OCTA).
CASE REPORT
OCTA was performed in a patient with BRAO at initial examination and 6 hours later. Initially, the occluded retinal artery and its branches were not detected on OCTA whereas a slow perfusion was present on fluorescein angiography. Six hours after initial examination, flow was detected on OCTA image in the previously occluded artery.
CONCLUSION
This case confirmed the relevance of using OCTA in monitoring BRAO and showed that capillaries with a very slow flow are not visible on OCTA angiograms. It emphasizes that non-perfusion on OCTA should be interpreted with caution.
目的
我们报告了在1例接受光学相干断层扫描血管造影（OCTA）成像的视网膜分支动脉阻塞（BRAO）病例病程中血流血管造影的变异性。
病例报告
对1例BRAO患者在初次检查时及6小时后进行了OCTA检查。最初，在OCTA上未检测到阻塞的视网膜动脉及其分支，而荧光素血管造影显示存在缓慢灌注。初次检查6小时后，在OCTA图像上检测到先前阻塞动脉的血流。
结论
该病例证实了使用OCTA监测BRAO的相关性，并表明血流非常缓慢的毛细血管在OCTA血管造影上不可见。它强调对OCTA上的无灌注情况应谨慎解读。
