Fig. 5.

Two en face volumes of a subject with GA were aligned, flattened, cleared of retinal vasculature via masking and cropped to produce a (A) $1.0\text{mm}\times 1.1\text{mm}$ OCT image of the RPE layer. The 7 GA lesions (a-g) are traced in yellow. When (B) overlaid on an OCTA en face image of the choriocapillaris in the same location, these regions highlight vascular abnormalities. When (C) overlaid on an OCTA en face image of the choroid in the same location, these regions show increased signal. On the choriocapillaris layer, they contain (D) increased flow-void radius and (E) reduced vessel radius, as compared to areas without GA lesions. Lesions d and e are excluded from analysis because retinal vasculature shadows overlap them. Error bars are $95\mathrm{\%}$ confidence intervals.
