the retina was formed at the age of 24 hours of incubation from ganglion cell layer (Gcl)inner nuclear layer(Inl).And then followed by the other layers that fit their appearance with the age of the embryo, completed growth and the emergence of layers of the retina at the age of almost 30 days after hatching.
