Analysis of the perfused vessel density in optical coherence tomography angiograms of the sublingual microcirculation. En face optical coherence tomography (OCT) angiogram (A) of the sublingual microcirculation. For analysis of the perfused vessel density (PVDby OCTA), a picture section (box with dashed line; 858 × 688 µm) was exported from the OCT angiogram, within which the vessel length relative to the image size was determined. Picture (B) shows a picture of the sublingual microcirculation recorded by incident dark field illumination (688 × 688 µm).
