[2] The function of these glands are to produce tears which are secreted onto the surface of the conjunctiva.
[3] 20 to 40 glands of Krause are found in the upper fornix, and 6-8 glands appear in the lower fornix. [4] There are usually 2 to 5 Ciaccio's glands, and are found along the superior tarsal border of the upper eyelid. [1] Popov’s glands are located within the substance of the caruncle. [1]
