Evolution of vessel intensity over OCTA slabs located at different depths and vessel drawings.

A: 130 (depicting deep vascular plexus), B: 150, C: 170 and D: 190 microns away from PR 1 layer (depicting superficial vascular plexus), E: An inset from C (in blue), drawing vessel ROI markings for pixel intensity analysis on an OCTA map. Different VOI indicated by the numerical code at the center of the marking. F: Reference AO DIV image with vessels labelled numerically that matches with E.
