Figure Lengend Snippet: Correspondence between structural and angiographic HighRes OCT scans of the deep capillary plexus draining venules. (A) HighRes OCT B-scan of the inferotemporal parafoveal region. The inset highlights an oblique vessel ( yellow arrow ) crossing the inner nuclear layer. Superficial plexus vessels are labeled as veins ( blue arrows ) and arteries ( red arrows ) in the registered near-infrared reflectance image (B). (C) An en face view of the DCP registered with structural HighRes OCT demonstrates the origin of the vessel at the convergence of several DCP capillary size vessels (DCP vortex). (D) Three-dimensional visualization shows a course between the DCP ( dark blue ) and an SVC venule ( light blue ), supporting that this vessel is a DCP draining venule.

Article Snippet: When connecting vessels were identified, the display was set to 1:1 pixel to micrometer scaling before measuring vascular diameter with the HighRes OCT software caliper tool.

Figure Lengend Snippet: Schematic representation of the parafoveal vascular network demonstrating the most frequently observed connectivity patterns observed with HighRes OCT. Superficial arteries supply the network through large arteriolar connections to the SVC and ICP. DCP inflow derives from small vessels succeeding ICP arterioles. Venules originate from the convergence of capillaries in every plexus. SVC draining venule is the venule that abuts most frequently the superficial vein and often receives venules from the plexuses below. DCP draining venules angle toward a superficial vein and typically receive ICP draining venules prior to reaching this target. The schematic representation demonstrates a hybrid model of flow between arteries and veins in the human parafovea, with a parallel circuit in the SVC and ICP and an in-series circuit through the DCP.
