What is the definition of Dacryoadenitis?

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

What are the causes for Dacryoadenitis?

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

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

What are the symptoms for Dacryoadenitis?

Symptoms may include:

  • 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 nodes in front of the ear

What are the current treatments for Dacryoadenitis?

If the cause of dacryoadenitis is a viral condition such as mumps, rest and warm compresses may be enough. In other cases, the treatment depends on the disease that caused the condition.

What is the outlook (prognosis) for Dacryoadenitis?

Most people will fully recover from dacryoadenitis. For more serious causes, such as sarcoidosis, the outlook depends on the disease that caused this condition.

What are the possible complications for Dacryoadenitis?

Swelling may be severe enough to put pressure on the eye and distort vision. Some people who were first thought to have dacryoadenitis may turn out to have cancer of the lacrimal gland.

When should I contact a medical professional for Dacryoadenitis?

Contact your health care provider if swelling or pain increase despite treatment.

How do I prevent Dacryoadenitis?

Mumps can be prevented by getting vaccinated. You can avoid getting infected with gonococcus, the bacteria that cause gonorrhea, by using safe sex practices. Most other causes cannot be prevented.
