Also described as a blocked tear duct. ==Causes, incidence, and risk factors== [[Acute (medical)|Acute]] dacryoadenitis is most commonly due to [[virus|viral]] or [[bacterium|bacteria]]l [[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. ==Symptoms == * Swelling of the outer portion of the upper lid, with possible redness and tenderness * [[Pain]] in the area of swelling * Excess tearing or discharge * Swelling of [[lymph node]]s in front of the [[ear]] ==Signs and tests== Dacryoadenitis can be diagnosed by examination of the [[eye]]s 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. ==Treatment== 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. ==Prognosis== Most patients will fully recover from dacryoadenitis. For conditions with more serious causes, such as sarcoidosis, the [[prognosis]] is that of the underlying condition. ==Complications== Swelling may be severe enough to put pressure on the eye and distort [[Visual perception|vision]]. Some patients first thought to have dacryoadenitis may turn out to have a [[malignancy]] of the lacrimal gland. ==Prevention== Mumps can be prevented by [[immunization]]. Gonococcus, bacteria can be avoided by the use of [[condom]]s. Most other causes cannot be prevented. ==External links== * [http://www.nlm.nih.gov/medlineplus/ency/article/001625.htm Source (NIH/Medline)] * [http://www.emedicine.com/oph/topic594.htm eMedicine] * [http://dro.hs.columbia.edu/dacryoadenitis.htm Photo (at Columbia)] * {{DiseasesDB|3430}} {{Eye pathology}} [[Category:Ophthalmology]] [[Category:Inflammations]] [[de:Tränendrüsenentzündung]] [[it:Dacriocistite]]
