What is a dacryocystitis?

Dacryocystitis is an inflammation usually caused by a lachrymal sac infection, arising from an obstruction of the tear duct.

What are its symptoms?

Pain, redness and edema at the level of the internal side of the lower eyelid (under the lachrymal sac), tearing, discharges, occasional or recurrent fever.

What are its signs?

Painful and erythematous edema located in the level of the nasal side of the lower eyelid, spreading towards the area of nasal periorbit. When pressure is put on the lachrymal sac, mucous or purulent discharges may go out through the lachrymal punctum.

Other signs are the creation of a fistula (usually with emergency point at the level of the medial canthal tendon) or a cyst in the lachrymal sac or mucocele, especially in chronic cases. There are rarely complications such as orbital or facial cellulitis.

What are its causes?

The most common cause is the obstruction of nasolachrymal duct, although less frequently it can be caused by other conditions, such as face trauma, previous nose surgery or tumours.

Management

It depends on the symptoms degree of gravity and the signs found during the exploration performed by the specialist. It requires a comprehensive ophthalmology examination and, when possible, the obtainment of a culture of any secretion extracted from lachrymal punctum.

Treatment

  • Systemic antibiotics. The antibiotic treatment is adjusted depending on the clinical response and the results of cultures and antibiograms
  • Topical antibiotic eye drops.
  • Warm compresses and a mild massage at the internal canthus level.
  • Analgesics whenever they are necessary.
  • Incision and drainage, to be assessed in case of mature abscess. These will always be performed by a specialist.
  • Once the acute process is gone, surgical treatment may be considered, especially in cases of chronic dacryocystitis. This is the only healing treatment for this diseases, as, if the obstruction is not resolved, the occurrence of infections may be repeated.
