Geographic atrophy (GA) in the foveal region due to age-related macular degeneration (AMD) imaged with (a) short-wavelength autofluorescence (SW-AF) to detect lipofuscin, and (b) near-infrared autofluorescence (NIR-AF) to detect melanin. Areas of hypo-fluorescence (c, d) corresponds to GA. Larger areas of hypo-fluorescence are detected with (c) SW-AF compared to (d) NIR-AF, which may indicate that SW-AF overestimates areas affected by GA in the fovea.
