Study Notes
- Lacrimal glands are exocrine glands that secrete lacrimal fluid onto the surfaces of the eye.
- 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.
