DEFINITION of Dacryoadenitis

Dacryoadenitis involves swelling and irritation of the almond-sized lacrimal glands, which produce tears for the eye’s aqueous layer; it disrupts tear production and causes orbital discomfort, potentially leading to fibrosis in chronic cases.


ETYMOLOGY of Dacryoadenitis

greek Dacryoadenitis breaks down as o- (tear, from Greek δάκρυ, dákry, tear) + o- (gland, from Greek ἀδήν, adḗn, acorn/gland) + -itis (inflammation, from Greek -ῖτις, -îtis, pertaining to disease).


CAUSES

  • Acute: Viral (e.g., mumps, EBV, adenovirus), bacterial (e.g., Staphylococcus, gonococcus), or rarely fungal.
  • Chronic: Autoimmune (e.g., Sjögren’s, sarcoidosis, thyroid eye disease), idiopathic, or infiltrative (e.g., lymphoma).
  • Symptoms
  • Common signs include upper eyelid swelling (often S-shaped), pain/tenderness in the superotemporal orbit, redness, excess tearing or discharge, and preauricular lymph node swelling; severe cases may cause proptosis or vision distortion.
