: tarsus) or tarsal plates are two comparatively thick, elongated plates of dense connective tissue, about 10 mm (0.39 in) in length for the upper eyelid and 5 mm for the lower eyelid; one is found in each eyelid, and contributes to its form and support.

[1] The tarsus has a lower and upper part making up the palpebrae.

To the anterior surface of this plate the aponeurosis of the levator palpebrae superioris is attached.

The free or ciliary margins of these plates are thick and straight.
