The evagination from the neural tube of the developing embryo which develops the optic cup at its extremity; the stalk persists as the optic nerve. [TFD][VHOG]
(...) an essentially similar sequence of events occurs during the embryonic development of the vertebrate eye. 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.[well established][VHOG]
