DEVELOPMENT
OF RETINA
2 divisions of optic cup
Orbital part of retina - larger, thicker,
posterior part
Ciliary and iridial parts of retina -
thinner, anterior part
2 layers of optic cup
The outer layer of the optic cup is known as the pigmented
layer of the retina.
Development of the inner neural layer of the optic cup is more
complicated.
The posterior four-鍖fths, cells of the pars optica retinae,
differentiate into light-receptive elements, rods and cones.
Adjacent to this photoreceptive layer is the mantle layer,
which gives rise to neurons and supporting cells, including the
outer nuclear layer, inner nuclear layer and ganglion cell layer.
The space between pigmented and nervous layers is called the
interretinal space that represents the original cavity of optic
cup.
