A, Geographic atrophy (GA) area as a function of time in unifocal and multifocal groups. The data were generated by converting the y-axis of Figure 10B from effective radius to area. At the same duration of GA, the area growth rate of multifocal GA is 2.14-folds higher than the growth rate of unifocal GA. At the same lesion size, the area growth rate of multifocal GA is 1.46-folds (between 2 and 3) higher than the growth rate of unifocal GA. B, The difference between the natural history of unifocal and multifocal GA disappears after dividing the area of multifocal GA by a factor of 2.
