Comparison of the choriocapillaris vasculature between acute and chronic CSC on OCTA, OCT, and processed images. (Top) Raw en-face slab obtained at the choriocapillaris level. (Middle) Binarized image heat-mapped according to vessel diameter. (Bottom) Skeletonized images. (A column) OCTA imaging of an acute CSC case. (B column) OCTA imaging of a chronic CSC case. (C column) OCT imaging of the acute CSC case shown in (A). (D column) OCT imaging of the chronic CSC case shown in (B). Higher densities of a more regular-diameter choriocapillaris are observable in the acute CSC case compared to the chronic CSC case on OCTA and OCT imaging, and vessel visualization is better with OCTA compared to OCT.
