Examples of fundus autofluorescence (FAF) images showing quantification of geographic atrophy (GA) in patients with age-related macular degeneration (AMD) using a modified fundus camera. Three images on the same line include the fundus image (Left), the original FAF image (middle) and the cropped image (right). Atrophic areas are highlighted in red. Images were classified in accordance with different patterns of hyper-autofluorescence in the junctional zone of GA. (a) Right eye of a 73-year-old patient showing GA with no increased autoflorescence intensity (None or Minimal change). Very small area of hyper-autofluorescence at the junctional zone of GA is minimal variation of the None pattern. (b) Left eye of a 68-year-old patient with small areas of focally increased autofluorescence at the margin of the atrophic area (Focal). (c) Right eye of a 58-year-old patient with areas of focally increased autofluorescence, which is larger than that of the Focal pattern (Patchy). (d) Left eye of a 71-year-old patient with a band of increased autofluorescence surrounding the geographic atrophy (Banded). (e) Left eye of a 79-year-old patient with many variable shapes of hyper-autofluorescent spot around GA (Diffuse).
