Another type of accessory lacrimal gland are "Krause's glands", which are smaller, more numerous than "Ciaccio's glands" and are found along the superior and inferior fornices of the conjunctival sac. Ciaccio's glands Ciaccio's glands or Wolfring's glands are small tubular accessory lacrimal glands ("glandulae lacrimales accessoriae") found in the lacrimal caruncle of the eyelid.

Meibomian gland eye conditions. They may also contribute to blepharitis. The glands are named after Heinrich Meibom (1638–1700), a German physician. Lipids are the major components of meibum (also known as "meibomian gland secretions"). The term "meibum" was originally introduced by Nicolaides "et al." in 1981. The biochemical composition of meibum is extremely complex and very different from that of sebum. Lipids are universally recognized as major components of human and animal meibum. Recently, an update on the composition of human meibum and on the structures of various positively identified meibomian lipids was published. Currently, the most sensitive and informative approach to
