The eye initially develops as a single median evagination of the diencephalon that soon bifurcates to form the paired optic vesicles. As each optic vesicle grows towards the body surface, its proximal part narrows as the optic stalk, and its distal part invaginates to form a two-layered optic cup. (...) The outer layer of the optic cup becomes the pigment layer of the retina, whereas the inner layer differentiates into the photoreceptive cells and neuronal layers of the retina.[well established][VHOG] EHDAA2:0001304 ZFA:0001071 UBERON:0005425 Portion of tissue that is the inner layer of the optic cup and will become the neural retina. presumptive retina optic cup inner layer future NR future neural retina inner layer optic cup presumptive retinas presumptive structure
