The orbital septum (palpebral ligament) is a membranous sheet in the upper eyelid, attached to the edge of the orbit, where it is continuous with the periosteum.
It blends by its peripheral circumference with the tendon of the Levator palpebræ superioris and the superior tarsus, in the lower eyelid with the inferior tarsus.
Medially it is thin, and, becoming separated from the medial palpebral ligament, is fixed to the lacrimal bone immediately behind the lacrimal sac.
The septum is perforated by the vessels and nerves which pass from the orbital cavity to the face and scalp.
The eyelids are richly supplied with blood.
