Background: One of the most common infections in neonatal period is ophthalmia neo-natorum. In this study, the bacterial agents, drug resistance and susceptibility of bacteri-al agents were studied.Methods: In this study a total of 72 newborns with ophthalmia neonatorum admitted in Bahrami Hospital in Tehran during the years 2008-2011 were continuously enrolled in a case series, descriptive study. Demographic data, including age, sex, cause of admis-sion and culture of discharge from the eyes and its antibiogram, as well as experimental treatments and treatment outcomes were collected.Results: Forty four infants (61.1%) were males and 28 (38.9%) were females and the mean age on admission was 11.6±7.7 days. In 51 patients (70.8%) the onset of ophthal-mia neonatorum was prior to admission. More than 56% of cases with ophthalmia neonatorum were associated with sepsis. On the other hand, positive blood culture was detected in 15.3% of cases. Among 72 neonates with ophthalmia neonatorum, 26 (36.1%) had a positive culture of the eye discharge. The most common causes of bacterial agents were Staphylococcus aureus (46.1%) (12 of 26 cases). Other causes included streptococcus species (23%), Pseudomonas (15.3%), E-coli (11.5%) and Haemophilus influenza (3.8%). The most frequent causes of drug resistance were Ampicillin, Penici-llin, Cefixime, and Ceftazidime (100% resistance). The most sensiti-ve antibiotics were vancomycin and imipenem (100% sensitivity). Based on the conventional treatment, clinical response to local gentamicin was approximately 60%. Sulfacetamide was associated with no clinical response in 40% of cases.Conclusion: The antibiogram and clinical response to empiric treatment showed that resistance to ampicillin and some third generation of cephalosporine was 100%. Aminoglycosides’ sensitivity was more than 50% locally and systemically. Our recommendation is performing eye discharge culture before antibiotic treatment. More studies with numerous cases should be done for better definition of bacterial resistance.
