A 20° SLO image with 15×15° OCT angiography slab, 150 μm thick, referenced to the ILM. B. OCT angiography slab following accentuation using a Frangi filter. C. Threshold image used for calculating vessel density. D. The three ellipses correspond to the best fit to the BMO, an eccentricity of 500 μm from the BMO, and an eccentricity of 1000 μm from the BMO.
