Comparison of the Haller’s layer vasculature between acute and chronic CSC on OCTA, OCT, and processed images. (Top) Raw en-face slab obtained from Haller’s layer. (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). Greater diameter variation of choroidal vessels is observable in the chronic CSC case compared to the acute CSC case on OCTA and OCT imaging. Vessel visualization is better with OCT compared to OCTA.
