Figure 1. Examples of Progression of Lesions of Definitely Decreased Autofluorescence and Questionably Decreased Autofluorescence.
A, A lesion of definitely decreased autofluorescence (7.87 mm2) at baseline. B, The same eye after 12 months; the lesion is enlarged to 8.48 mm2. C, A lesion of questionably decreased autofluorescence at baseline (2.45 mm2). D, The same eye after 12 months, with the lesion enlarged to 2.90 mm2. Red indicates an excluded area without definitely decreased autofluorescence.
