Percent VA in choroids in aged control and subjects with GA. Representative higher-magnification images of UEA-stained choroidal flat-mounts showing the submacular and paramacular choroidal vasculature in three aged control eyes and three GA donor eyes. Reduced vascular area is observed in the submacular region (C, G, K) of GA choroids compared to that in controls (A, E, I). In the paramacular region, the vascular area was similar in control (B, F, J) and GA (D, H, L) choroids. Remaining viable CC luminal diameters in GA submacula is also significantly constricted compared to aged controls. Scale bar in A indicates 100 µm for all panels.
