Dots = dot-shaped lesions; Mixed = both morphologies; MQ = multiquadrant; N = nasal; NIR RPD Distribution: NIR = near-infrared reflectance; Ribbon = ribbon-shaped lesions; RPD = reticular pseudodrusen; S = superior; SD = standard deviation; T = temporal.
∗
N Instances/Images = number of visits.
†
Mean RPD Contour Area on NIR = NIR-based contour area of concave hull around the RPD lesions from reading center grading, only for images with definite RPD.
