An article about the lacrimal artery, its anatomy, and function


Lacrimal artery[edit | edit source]

The lacrimal artery is a significant blood vessel in the human body that supplies blood to the lacrimal gland, the eyelids, and the conjunctiva. It is a branch of the ophthalmic artery, which itself is a branch of the internal carotid artery.

Anatomy[edit | edit source]

The lacrimal artery arises from the ophthalmic artery shortly after it enters the orbit through the optic canal. It travels along the superior border of the lateral rectus muscle, towards the lacrimal gland.

Branches[edit | edit source]

The lacrimal artery gives off several branches:

Function[edit | edit source]

The primary function of the lacrimal artery is to supply oxygenated blood to the lacrimal gland, which is responsible for the production of tears. It also supplies blood to the eyelids and the conjunctiva, playing a crucial role in maintaining the health and function of the eye and its associated structures.

Clinical significance[edit | edit source]

The lacrimal artery is important in ophthalmic surgery and orbital surgery. Damage to this artery can lead to complications such as ischemia of the lacrimal gland or eyelid tissues. Understanding its course and branches is essential for surgeons operating in the orbital region.
