Uberon Homology note : The folded arrangement of the vertebrate retina and RPE [retinal pigment epithelial]
provides an evolutionary explanation for the occurrence of the choroid fissure, as
proposed more than a century ago. Early in evolution, before the optic cup invaginated,
the axons from retinal ganglion cells would simply have run over the surface of the
structure. Hence, one can view the optic nerve as having acted rather like a rope
in linking the retina to higher centres: the developing eye cup has simply wrapped
around this 'rope', and the developing axons have thereby not needed to penetrate
the retina.[well established][VHOG];
