Representative exported and processed images. SS-OCTA and en face images were exported from the retinal superficial layer (A), choriocapillaris (B), inner choroid (inner cho, E), mid-choroid (mid cho, H), and outer choroid (outer cho, K). These images were first aligned to the retinal superficial layer and then binarized in ImageJ (C, F, I, L).
