Organ of Vision (Eye)
Blood and Lymphatic Vessels of the Organ of Vision

The Eyeball and its accessory structures receive Blood from Branches of the ophthalmic artery (a. ophthalmica), which in turn is a branch of the Internal Carotid Artery. The vascular tunic of the eyeball is formed by branches of the long and short posterior ciliary Arteries. The retina is supplied with blood by the central retinal artery. The eyelids are supplied by the lateral and medial palpebral arteries, which form the superior and inferior palpebral arcades within the thickness of the eyelids; the eyebrows, by the supratrochlear artery; the lacrimal gland, by the lacrimal artery; and the conjunctiva, by the anterior and posterior conjunctival arteries (all of which are collateral branches of the ophthalmic artery).

Venous blood from the eyeball drains via the vortex Veins, the central retinal vein, and the ophthalmic veins into the cavernous sinus. From the eyelids, eyebrows, and conjunctiva, blood flows into the facial vein.

Lymphatic vessels from the eyelids, conjunctiva, and eyebrows drain into the mandibular, submandibular, and parotid Lymph Nodes.
