Is an ocular vasculature that develops adjacent to the pigment epithelium of the eye. The optic choroid vascular plexus develops from the primitive mesencephalic artery. Initially blood enters from the mesencephalic central artery, and the dorsal ciliary vein. The plexus drains via the ophthalmic vein. The plexus supplies blood to the retina.
