Fundus autofluorescence of the RE (left) and LE (right). Baseline frames (top) and 12-year’s frames (bottom). There is a slight progression of atrophy only in the RE after 12 years (hypoautofluorescent area, white arrow, left). Progression of atrophy is larger in the LE though (white arrow, right), where the encircled white area (bottom right) matches the drawn area of atrophy at baseline (top right)
