part of optic cup morphogenesis involved in camera-type eye development optic cup morphogenesis involved in camera-style eye development biological_process GO:0002072 The invagination of the optic vesicle to form two-walled indentations, the optic cups, that will go on to form the retina. This process begins with the optic vesicle becoming a two-walled structure and its subsequent shape changes. It does not include the fate commitment of cells to become the pigmented retina and the neural retina. An example of this process is found in Mus musculus. morphogenesis of embryonic epithelium embryonic camera-type eye formation
