Dacryocystitis

Dacryocystitis is an infection of the nasolacrimal sac, frequently caused by nasolacrimal duct obstruction. The term derives from the Greek dákryon (tear), cyst (sac), and -itis (inflammation). It causes pain, redness, and swelling over the inner aspect of the lower eyelid and epiphora. When nasolacrimal duct obstruction is secondary to a congenital barrier it is referred to as dacrocystoceles. It is most commonly caused by Staphylococcus aureus and Streptococcus pneumoniae. The most common complication is corneal ulceration, frequently in association with S. pneumoniae. The mainstays of treatment are intravenous antibiotics, warm compresses, and relief of nasolacrimal duct obstruction by dacryocystorhinostomy.
