Infraorbital vein

Infraorbital vein is a blood vessel that is part of the human anatomy. It is located in the face and is responsible for draining blood from the eye socket and surrounding areas.

Anatomy

The infraorbital vein begins in the eyelid and runs through the infraorbital canal to join the facial vein. It is closely associated with the infraorbital artery and infraorbital nerve, which run alongside it.

Function

The primary function of the infraorbital vein is to drain deoxygenated blood from the lower eyelid, cheek, and upper lip. It then carries this blood to the facial vein, which eventually drains into the internal jugular vein.

Clinical significance

Due to its location, the infraorbital vein can be affected by various medical conditions. For example, trauma to the face can cause damage to the vein, leading to bruising or hematoma. Infections in the eye socket or surrounding areas can also spread to the infraorbital vein, potentially leading to thrombosis or sepsis.
