En-face images of Sattler’s and Haller’s layers after flattening of Bruch’s membrane.

(A, C, E) Raw images, and (B, D, F) processed images after the flattening of chorio retinal images using Bruch’s membrane as a reference surface. En-face images after flattening at the levels of Sattler’s layer (D) and Haller’s layer (F) delineate choroidal vessels clearly, compared to en-face images before flattening (C, E).
