Representative example of image export and processing. SS-OCTA and en face SS-OCT images are exported from the choriocapillaris (A, I), inner choroid (B, J), midchoroid (C, K), and outer choroid (D, L). These images are then binarized in ImageJ using the Niblack local thresholding algorithm (E–H, M–P), which are used to calculate choroidal vessel density.
