Tarsal plate

Last revised by Craig Hacking on 27 Mar 2024

The tarsal plates of the eye are formed by dense fibrous tissue representing thickened extensions of the orbital septum, molded to the curvature of the eyeball. Each eye has a superior tarsal plate and an inferior tarsal plate, located in their respective eyelid

The plates anchor the roots of the eyelashes and contain tarsal (Meibomian) glands. These modified sebaceous glands secrete oil which makes the lid margins waterproof, mitigates against the tears dripping and delays tear evaporation.
