Blood vessels of the eyeball

This tutorial covers the blood vessels of the eyeball, focusing on the arteries and veins that supply the eye. It begins with an overview of the eye's function and structure, then delves into the ophthalmic artery and its branches, including the central retinal artery and ciliary arteries. The tutorial also explains the veins of the eyeball, particularly the vortex veins, and concludes with clinical notes on potential pathologies related to eye blood vessels, such as retinal artery occlusion and ocular stroke.

What is the primary function of the eyes?

• To produce tears

• To perceive vision

• To regulate body temperature

What do the muscular branches of the ophthalmic artery supply?

• The iris

• The optic nerve

• The extraocular muscles

• The retina

Which arteries supply the conjunctiva and sclera?

• Central retinal arteries

What is the clinical significance of the vortex veins?

• They supply the retina

• They drain the conjunctiva

• They drain the ocular choroid

• They supply the optic nerve

What is a common cause of ocular stroke?

• Inflammation of the sclera
