Dacryoadenitis is inflammation of the lacrimal glands (the tear-producing glands). Also described as a blocked tear duct.
Additional recommended knowledge
Causes, incidence, and risk factors
Chronic dacryoadenitis is usually due to noninfectious inflammatory disorders. Examples include sarcoidosis, thyroid eye disease, and orbital pseudotumor.
Signs and tests
Dacryoadenitis can be diagnosed by examination of the eyes and lids. Special tests such as a CT scan may be required to search for the cause. Sometimes biopsy will be needed to be sure that a tumor of the lacrimal gland is not present.
If the cause of dacryoadenitis is a viral condition such as mumps, simple rest and warm compresses may be all that is needed. For other causes, the treatment is specific to the causative disease.
Most patients will fully recover from dacryoadenitis. For conditions with more serious causes, such as sarcoidosis, the prognosis is that of the underlying condition.
Swelling may be severe enough to put pressure on the eye and distort vision. Some patients first thought to have dacryoadenitis may turn out to have a malignancy of the lacrimal gland.
