Lacrimal fluid cleans, nourishes, and lubricates the eyes.
The gland is located in the superolateral aspect of the orbit, within the lacrimal fossa.
It is approximately 2cm long and can be divided into two main parts.
The lacrimal fluid is secreted into excretory ducts, which empty into the superior conjunctival fornix.
The lacrimal apparatus is responsible for the drainage of lacrimal fluid from the orbit.
The lacrimal artery supplies blood to the gland, and the superior ophthalmic vein drains it.
The lacrimal gland is innervated by the lacrimal nerve and receives autonomic nerve fibers.
Dacryoadenitis is inflammation of the lacrimal glands.
It can cause swelling, pain, excess tear production, and visual impairment.
