OCTA extraction for vessel depth analysis.

A: Enface image of the OCTA data showing perfused vessels of the chosen slab thickness. Crosshairs are positioned at a vessel segment of interest located 1.25° superior to FAZ (green line represents transverse scan and blue is the orthogonal scan). B: A close up view of Structural OCT section images with overlay of OCTA data in yellow, showing thickness slab (in red dashed lines pointed by blue arrow) positioned 160 microns away from photoreceptor layer 1 (indicated by orange arrow).
