Fig. 3

Left panel: 6 × 6 mm enface OCTA scan demonstrating partial attenuation of FAZ contour in the pseudoaveraged scan at about 6 o’clock (middle) compared to the original scan (top). However, after adjusting the brightness/contrast histogram in image J, the vessel is no longer as attenuated and FAZ contour becomes more visible (bottom image) indicating that FAZ contour attenuation is at least partially due to inadequate brightness/contrast adjustment and not only due to pseudoaveraging. Right panel: cropped 6 × 6 mm enface OCTA scan from an eye with diabetic retinopathy. The arrows in the bottom image point to subtle residual FAZ noise in the pseudoaveraged scan (bottom scan)
