Abstract
The postnatal development of the area centralis of the kitten retina was followed using EM. After birth, small but well developed photoreceptor outer segments were observed. Cone pedicles formed triads and biplar cells formed dyads; so, potentially, cone pathways to the ganglion cell were present at this time. By the start of the 2nd week, rod spherules formed shallow invaginations containing both central and lateral processes and rod bipolar cells formed dyads. Potentially, rod pathways to the ganglion cell were present. By the end of the 3rd week, the area centralis was sufficiently well developed to take advantage of the clearing of the optical media which occurs in postnatal development. Maturity was attained during the 5th week.
