Meibomian Glands

 

(tarsal glands), modified sebaceous glands in the tissue of the eyelids in man and most mammals (except monotremes and aquatic species); named for the German anatomist H. Meibom (1638–1700).

Each meibomian gland consists of numerous alveoli that discharge a secretion into a common efferent duct that opens onto the edge of the eyelid at the base of the eyelashes. The secretion is fatty and serves to coat the eyelids, protecting their edges from wetting by tears; it also contains bactericidal substances. There are 30–40 of the glands in the human upper lid and 20–30 in the lower.

The underlying issues involved in dry eye syndrome are simple: Too little watery tear production in the lacrimal glands means not enough water gets into your tears to fully moisten the eye surface, while too little oil production in the Meibomian glands means too much water evaporates from the eye surface, again leaving it exposed to damage.
