Krause's glands the conjunctiva. Krause's glands are named after German anatomist Karl Friedrich Theodor Krause (1797–1868). Krause's glands Krause's glands are small, mucous accessory lacrimal glands that are found underneath the eyelid where the upper and lower conjuctivae meet. Their ducts unite into a rather long sinus which open into the fornix conjunctiva. There are approximately forty Krause glands in the region of the upper eyelid, and around 6 to 8 in the region of the lower lid. The function of these glands are to produce tears which are secreted onto the surface of the conjuctiva. There are rare instances of tumors
Meibomian gland lipidomic analysis of meibum is mass spectrometry either with direct infusion or in combination with liquid chromatography. In humans, more than 90 different proteins have been identified in meibomian gland secretions. Dysfunctional meibomian glands often cause dry eyes, one of the more common eye conditions. They may also contribute to blepharitis. Inflammation of the meibomian glands (also known as "meibomitis", "meibomian gland dysfunction", or "posterior blepharitis") causes the glands to be obstructed by thick waxy secretions. Besides leading to dry eyes, the obstructions can be degraded by bacterial lipases, resulting in the formation of free fatty acids, which irritate the
