Visibility of blood flow on optical coherence tomography angiography in a case of branch retinal artery occlusion
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 occlud...

| Summary: | 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. |
