WebIn the developing human retina, cones are generated and specified in a series of waves starting from the foveola and moving out to the periphery (Fig. 6). Cones are first specified during week 11 of fetal development as S cones are generated in the central retina. S cones are then specified in a wave that spreads out to the periphery.
