Previously it was thought that the main lacrimal gland is responsible for reflex tear secretion and the accessory lacrimal glands of Wolfring and Krause are responsible for the basal secretion. But recent evidence suggests that all tearing may be reflex. [5] The accessory glands account for approximately 10% of the total lacrimal secretory mass ...
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 ...
They are sometimes called "Wolfring's glands" after Polish ophthalmologist Emilj von Wolfring (1832-1906), who described them during the same time period as did Ciaccio. 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 ...
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.
As with all oil glands, lacrimal caruncles can become clogged, causing a pimple, whitehead, or pustule beneath the skin. Clogged oil and sweat glands in the caruncle can affect tear ducts. Treatment for dry eyes due to clogged glands includes refraining from rubbing the eyes and rinsing the eyes with clear water frequently during the day ...
Karl Friedrich Theodor Krause (15 December 1797 – 8 June 1868) was a German anatomist born in Hanover. In 1818 he received his medical doctorate from the University of Göttingen, and later attained the chair of anatomy at the surgical school in Hanover. His son Wilhelm Krause (1833–1910) was also an anatomist.
The lacrimal sac or lachrymal sac [1] is the upper dilated end of the nasolacrimal duct, [2] and is lodged in a deep groove formed by the lacrimal bone and frontal process of the maxilla.
