Involutional stenosis is probably the most common cause of nasolacrimal duct obstruction in older people. It affects women twice as frequently as men. Although the inciting event in this process is unknown, clinicopathologic study suggests that compression of the lumen of the nasolacrimal duct is caused by inflammatory infiltrates and edema.
Psoriatic erythroderma can be congenital or secondary to an environmental trigger. [12] [13] [14] Environmental triggers that have been documented include sunburn, skin trauma, psychological stress, systemic illness, alcoholism, drug exposure, chemical exposure (e.g., topical tar, computed tomography contrast material), and the sudden cessation of medication.
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.
Historically, bilateral parotid and lacrimal gland enlargement was characterized by the term Mikulicz's disease if the enlargement appeared apart from other diseases. If it was secondary to another disease, such as tuberculosis, sarcoidosis, lymphoma, and Sjögren's syndrome, the term used was Mikulicz's syndrome.
The lacrimal apparatus is the physiological system containing the orbital structures for tear production and drainage. [1] It consists of: The lacrimal gland, which secretes the tears, and its excretory ducts, which convey the fluid to the surface of the eye; it is a j-shaped serous gland located in lacrimal fossa.
