Retinal vascular metrics difference by comparison of two image acquisition modes using a novel OCT angiography prototype

Panel A: Representation of the OCTA assessment of the superficial capillary plexus (SCP). The SCP was investigated in two different OCTA scan modalities: (i) 3x3-mm single volume scan (V1) (Top left), and (ii) 3x3 multiple-volume scan (V4) (bottom left). The SCP binarized (middle) and skeletonized (right) images, for both protocol scans, were analyzed to investigate both perfusion density (PD), and vessel length density (VLD), respectively. Panel B: Representation of the OCTA assessment of the deep capillary plexus (DCP). The DCP was investigated in two different OCTA scan modalities: (i) 3x3-mm single volume scan (V1) (top left), and (ii) 3x3 multiple-volume scan (V4) (bottom left). The DCP binarized (middle) and skeletonized (right) images, for both protocol scans, were analyzed to investigate both perfusion density (PD), and vessel length density (VLD), respectively.
