Postnatal development of the cat's retina: a concept of maturation obtained by qualitative and quantitative examinations.

From a coherent morphological and morphometrical investigation of the postnatal development of the cat's retina, some main aspects are presented concerning the structures lying outside the outer limiting membrane, the neuropile layers and the nuclear layers. It is shown by means of qualitative and quantitative results, that the maturation process of the various cellular elements in the cat's retina can be devided into three phases and is presumably finished between the 4th to the 5th month of life.
