Tarsal glands

The tarsal glands are modified sebaceous glands located in the tarsus of each eyelid. They are large, yellow and arranged in rows. They are partially visible through non-pigmented palpebral conjunctiva. Their excretory ducts form a line along the edge of the eyelids.

They create a lipid secretion called palpebral sebum, whose role is to prevent the tear film from escaping from the palpebral fissure by forming its superficial layer.
