the upper eyelid contains 2 to 4 rows of cilia (eyelashes), the lower eyelid does not contain cilia.1 The modified sweat glands, referred to as the glands of Moll, open onto the eyelid margin near the base of the cilia. The glands of Zeis are sebaceous glands that are found in the tarsal plate and open onto the eyelid margin posterior to the cilia. ................
