All OCTA images (left column) were converted to an 8-bit grayscale (center column) and white vessels reflectivity value was calculated in pixels. Pixels measurements of vessels reflectivity were both compared through a 3D rendering (right column), in which peaks height correspond to vessels intensity, and through a histogram (bottom panel). Iris vessels caliper and reflectivity on optical coherence tomography angiography is higher in the eye with 4+ cells (top row, orange line in the histogram), decreases in the eye with 2+ cells (second row, grey line in the histogram), and is barely detectable in a normal eye (third row, blue line in the histogram). In healthy subjects, iris vessels are scarcely visible through optical coherence tomography angiography, since the flow inside them is below the scan threshold
