Definition of Dacryoadenitis:

Dacryoadenitis is an inflammation of the tear-producing gland (lacrimal gland).

Causes, incidence, and risk factors:

Acute dacryoadenitis is most commonly due to viral or bacterial infection. Common causes include mumps, Epstein-Barr virus, staphylococcus, and gonococcus.

Chronic dacryoadenitis is usually due to noninfectious inflammatory disorders. Examples include sarcoidosis, thyroid eye disease, and orbital pseudotumor.
