FAZ area and vessel density measurements. Example of a patient with severe non proliferative diabetic retinopathy. Images in the left column were taken 12 months prior to images in the right column. a, c Superficial retinal slab projection showing automated FAZ area measurements. Note parafoveal capillary drop out and slight increase in FAZ area over time. b, d B-scan showing corresponding segmentation boundaries. e, f Vessel density map of the deep retinal slab for the same patient and timepoints. Note slight drop in vessel density in the superior quadrant. f, g B-scan with corresponding segmentation lines
