Multiple Choice

The lower edge of the upper lid or upper edge of the lower lid that contains the openings of the meibomian glands is called what?

The lid margin is the edge of the eyelid where the openings of the Meibomian glands are located. It forms the border of the palpebral fissure and includes the gland orifices that secrete the oily layer essential for tear film stability. The inner corner (medial canthus) is just the near-nose junction, the limbus is the border between cornea and sclera, and the gland openings themselves are just the openings, not the edge. So the term that describes the edge containing those openings is the lid margin.
