Progression of geographic atrophy (GA) with the adoption of an eccentric preferred retinal locus (PRL). (Left) At baseline, fixation (x) was placed centrally, with surrounding c-shaped geographic atrophy (circled white area). At this time, visual acuity was 20/118, and the total area of GA was 1.2 Macular Photocoagulation Study (MPS) disc areas. (Right) One year later, the GA has enlarged to 2.4 MPS disc areas and involves the central area. Fixation is now maintained superior to the atrophy on the retina, which corresponds to fixation with the scotoma above fixation in visual field space. Visual acuity is now 20/214.
