(A,B) Color fundus images with a superimposed square depicting the area scanned with spectral domain optical coherence tomography (SD-OCT) imaging. (C,D) Fundus autofluorescence images with a superimposed square depicting the area scanned with SD-OCT imaging. (E,F) Sub-RPE slabs. (G,H) En face images derived from the outer retinal slab described in Figure 1 with the superimposed images of GA (white) derived from the corresponding sub-RPE slabs at baseline.
