Fundus photographs from participants in the Age-Related Eye Disease Study (AREDS) illustrating eyes in age-related macular degeneration Categories 2 and 3. A, Left eye in Category 2 shows nonextensive intermediate drusen, mostly located superotemporal to the center of the macula. No druse is 125 μm or greater in diameter, although some are 63 μm or greater and their cumulative area is less than AREDS circle O-2 (about 0.2 disc areas). B, One left eye in Category 3 depicts the lower limit of the category, having 1 large druse (≥125 μm in diameter) in the 8-o’clock position from the center of the macula, while another left eye (C) shows many large drusen (totaling at least 1 disc area) scattered throughout the macula.
