part of part of optic choroid vasculature of head vasculature of eye vascular plexus optic choroid vascular plexus 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[ZFA:0005094]. The choroid of teleosts is a connective tissue layer rich in blood vessels, and one or two choroidal glands. choroid vasculature XAO:0004176 CVP TAO:0005094 ZFA:0005094 choroid vascular plexus Consider merging with capillary layer. Consider choriocapillaris complex choroidal vascular plexus UBERON:0010078 optic choroid vascular plexus A plexus of capillaries that is located anteromedial to the eye. It is a capillary layer in the choroid. It is in contact with the basal surface of the retinal pigmented epithelium and supplies the photoreceptors with oxygen and nutrients. The fused basement membrane of this capillary layer and the pigmented epithelium is called Bruchs's membrane.[XAO:0004176]. choriocapillaris capillary lamina of choroid
