Recent trends in chlamydial and gonococcal conjunctivitis among neonates and adults in an Irish hospital.
BACKGROUND
Chlamydia trachomatis and Neisseria gonorrhoeae are two important and frequently overlooked causes of neonatal and adult conjunctivitis.


OBJECTIVE
In order to improve primary treatment, prevention, and control of infection caused by these organisms, an analysis of all cases presenting from July 2002 to December 2006 at a major Irish regional teaching hospital was performed.


RESULTS
There were 51 cases of conjunctivitis in total. Among neonates and adults, C. trachomatis was the most common cause of conjunctivitis. Of the adult patients, 75% were men. The annual incidence of adult chlamydial conjunctivitis increased yearly from 2002 and correlated with an overall increase in genital chlamydia infection in the region. Neonatal chlamydial conjunctivitis has an overall incidence of 0.65/1000 live births and is continuing to rise annually. In 2006, gonococcal conjunctivitis accounted for 20% of all cases of conjunctivitis caused by sexually transmitted bacteria presenting to our hospital.


CONCLUSIONS
The recent increase in the incidence of gonococcal keratitis serves to remind us that this important infection should be borne in mind when treating cases of purulent conjunctivitis. The diagnosis of chlamydial and gonococcal conjunctivitis requires a high index of suspicion and prompt treatment with systemic antibiotics.
