Correlation between greater CRT and greater VFD in central 1 mm and smaller area of FAZ in 3 healthy subjects. a– c OCTA of the macula (above) with the corresponding OCTA scans at level of superficial retinal plexuses (below). a CRT of 298 mm with high VFD of 45.2% and small FAZ area of 0.105 mm². b CRT of 234 mm with lower VFD of 34.3% and larger FAZ area of 0.304 mm². c CRT of 207 mm with lowest VFD of 16.6% and largest FAZ area of 0.629 mm². In the thickest fovea (a), there is continuity of inner nuclear layer and ganglion cell layer over the foveolar center. In the thinnest fovea (c) there is a large cleavage of the inner retinal layers at the foveal center. From the thickest to the thinnest fovea, an increasing VFD is noted
