**5. SS-OCTA depiction of retinal vascular plexuses and the choriocapillaris in normal individuals**

Normally, the retinal superficial capillary plexus (SCP) appears on SS-OCTA as an interlacing network of horizontal arterioles and venules connected by transverse capillaries and anastomosing together to form the peri-foveal capillary circle. Arterioles are surrounded by a wider capillary-free zone compared to venules. The retinal deep capillary plexus (DCP) appears as polygonal lobules or vortices composed of capillaries converging radially on an epicenter. The choriocapillaris appears as a homogeneous hyperintense layer composed of densely packed capillaries with no intervening dark spaces [21, 27, 28].
