The ophthalmic artery is a crucial blood vessel that supplies oxygenated blood to the eye and its surrounding structures. It branches off from the internal carotid artery and enters the orbit through the optic canal, where it then divides into several smaller arteries. This artery provides blood to important areas, including the retina, eyelids, and parts of the forehead. It plays a vital role in maintaining the health and function of the eye, ensuring that these tissues receive the necessary nutrients and oxygen for proper operation.
