Graph showing the residual area of retinal pigment epithelium (RPE) as a function of age in 257 untreated eyes. The data appear to follow an exponential decay (r2 = 0.30) with data points scattered along the trendline. Note, some eyes have relatively large residual RPE area at advanced ages. We restricted the y-intercept of the exponential trendline (in red) to the mean maximal measurable RPE area in a 55° image (201.4 mm2), as suggested by Jolly et al19.
