To evaluate scotopic retinal organization in retinopathy of prematurity (ROP) through a study of spatial summation. Thresholds for a range of stimulus diameters (0.4°-10°) were measured using a two alternative, spatial, forced choice psychophysical procedure. The critical diameter (DCRIT) for comple...
