NCIt definition : Human Eye Development involves bilateral outpouchings of optic vesicles, from the
neural tube, that each form optic cups. By cell division, migration, differentiation,
and synaptogenesis, the inner surface becomes the multi-layer neuroepithelial retina;
the outer monolayer becomes the retinal pigment epithelium. Surface membranes cover
the eye and develop into the lens, iris and cornea.;
