Medial palpebral arteries

Medial Palpebral Arteries

Diagram of the blood vessels of the eyelid, showing the medial palpebral arteries.

The Medial Palpebral Arteries are two small blood vessels, superior and inferior, that supply blood to the eyelids. They originate from the Ophthalmic artery, a major branch of the Internal carotid artery.

Anatomy

The medial palpebral arteries arise from the ophthalmic artery as it courses through the orbit. The superior medial palpebral artery travels superiorly, supplying the upper eyelid, while the inferior medial palpebral artery travels inferiorly, supplying the lower eyelid.

These arteries anastomose, or connect, with the Lateral palpebral arteries, which are branches of the Lacrimal artery. This connection ensures a continuous blood supply to the eyelids, even if one of the arteries is blocked or damaged.

Clinical Significance

The medial palpebral arteries are important in a number of clinical procedures, including eyelid surgery and the treatment of certain eye conditions. Knowledge of their anatomy can help to avoid complications such as bleeding or damage to the eyelids.
