Anatomy of the posterior segment vasculature. Using Angiovue™ optical coherence tomography angiography (OCTA), the vascular plexus from the internal limiting membrane to the Bruch’s membrane of a healthy subject was non-invasively visualized in 3 × 3 mm (a), 6 × 6 mm (b), and 8 × 8 mm (c) angiograms. Intravenous Fluorescein Angiography (IVFA) cropped to 8 × 8 mm (d) shows less microvasculature detail than that of OCTA angiogram (a-c). The inner retinal vascular plexus is further separated into the superficial inner vascular plexus (e), which supplies the retinal nerve fiber layer and ganglion cell layer and the deep inner vascular plexus (f), which supplies the inner plexiform layer, inner nuclear layer, and outer plexiform layer [76]. No distinct vasculature can be detected in the outer retina (g) and choriocapillaris (h) using 3 × 3 mm OCTA. (Reprinted and modified from de Carlo et al.
