Krause's glands and Wolfring's glands (or Ciaccio's glands) are the accessory lacrimal glands of the lacrimal system of human eye. [1] These glands are structurally and histologically similar to the main lacrimal gland. Glands of Krause are located in the stroma of the conjunctival fornix, and the glands of Wolfring are located along the ...
The function of these glands are to produce tears which are secreted onto the surface of the conjunctiva. There are rare instances of tumors associated with Krause's glands. They usually occur as retention cysts in cicatricial conditions of the conjunctiva. Krause's glands are named after German anatomist Karl Friedrich Theodor Krause (1797 ...
Ciaccio's glands or Wolfring's glands are small tubular accessory lacrimal glands (glandulae lacrimales accessoriae) found in the lacrimal caruncle of the eyelid. These accessory lacrimal glands are located in the upper border of the tarsus , approximately in the middle between the extremities of the tarsal glands . [ 1 ]
The lacrimal gland is a compound tubuloacinar gland, it is made up of many lobules separated by connective tissue, each lobule contains many acini.The acini composed of large serous cells which, produce a watery serous secretion, serous cells are filled with lightly stained secretory granules and surrounded by well-developed myoepithelial cells and a sparse, vascular stroma.
Most lacritin is produced by the lacrimal gland, [4] including the accessory lacrimal gland of Wolfring. [10] Some lacritin is produced by the meibomian gland, and by epithelial cells of the conjunctiva and cornea. [11] Together these epithelia comprise much of the lacrimal functional unit (LFU). Dry eye is the most common disease of the LFU.

Merocrine – the cells of the gland excrete their substances by exocytosis into a duct; for example, pancreatic acinar cells, eccrine sweat glands [dubious – discuss], salivary glands, goblet cells, intestinal glands, tear glands, etc. Apocrine – the apical portion of the cytoplasm in the cell membrane, which contains the excretion, buds off.
Human Von Ebner's gland. Von Ebner's glands, also called Ebner's glands or gustatory glands, are exocrine glands found in the mouth. More specifically, they are serous salivary glands which reside adjacent to the moats surrounding the circumvallate and foliate papillae just anterior to the posterior third of the tongue in its submucosa, anterior to the terminal sulcus.
