Krause's glands are specialized glands located in the submucosal layer of the conjunctiva. These glands produce a watery fluid that helps keep the eye moist. There are several synonyms for Krause's glands including the lacrimal gland, the meibomian gland, and the glands of Wolfring. The lacrimal gland is responsible for producing tears to help lubricate and protect the eye, while the meibomian gland produces oil to prevent evaporation of tears. The glands of Wolfring are also located in the conjunctiva and produce a thicker, more viscous fluid than Krause's glands. All of these glands are crucial to the health and function of the eye.
