Name the arteries that supply the eyeball.
Understand the venous drainage of the eyeball.

Watch videos

The eyeball is a spherical sensory organ located in the bony orbit. It is the part of the eye, which participates in transmitting visual stimuli. It receives its main arterial supply via the ophthalmic artery that gives off several branches. The venous drainage occurs via the central retinal, superior ophthalmic, inferior ophthalmic, and middle ophthalmic veins. The veins drain an intricate venous network located between the different layers of the eyeball.

The following video will provide you with an overview of the blood vessels of the eyeball.
