WebIn detail, quantitative and qualitative analyses of the macular area were performed to quantify topographical retinal perfusion changes after surgery, calculating the foveal avascular zone (FAZ), vessel density (VD) and vessel length density (VLD) at the superficial capillary plexus (SCP) and deep capillary plexus (DCP). WebThe Foveal Avascular Zone (FAZ) is located within the central macular region, 1 where the retinal capillaries are absent. 2 This zone has the highest cone density 3,4 and overlays the inner retinal tissue. 4 This region is of clinical importance since the vascular arrangement around the fovea changes depending on the eye’s (disease or refractive) status.
