Figure 3. — Representative optical coherence tomography (OCT) B-scan of a patient with geographic atrophy (GA). OCT B-scan (left) showing the presence of choroidal hyper-reflective foci (HRF). A magnified visualization of the foveal region is reported on the right. Hyper-reflective deposits are localized near Bruch's membrane (orange asterisk) and within the choroidal stroma (orange arrowhead). Choroidal HRF exhibited varying effects on the posterior signal, including shadowing or hypertransmission, the latter characteristic causing a barcode effect within the underlying sclera (orange asterisks).
