Ophthalmia neonatorum in a semi-rural African community

Abstract

The incidence and aetiology of ophthalmia neonatorum have been estimated over a 7-month period in Franceville, a semi-rural community in south-eastern Gabon. Chlamydia trachomatis was the most frequently observed pathogen, being isolated from 17 babies (2.7% of births), and Neisseria gonorrhoeae was recovered from 12 (1.6% of births). 5 of 17 cases of chlamydial conjunctivitis were in infants less than 5 d old as opposed to 9 in the typical 5 to 10-days-old group. As expected, most cases of gonococcal ophthalmia neonatorum occurred in the first 5 d of life with cases in older infants often not accompanied by a granulocytic response. Chlamydial conjunctivitis was usually unilateral whereas other cases were most frequently bilateral.
