Summary of study design, objectives, and ongoing research findings
A randomised double-blind trial to compare the effectiveness of chloramphenicol eye drops with placebo in children with infective conjunctivitis in primary care. 326 children aged 6 months to 12 years with a clinical diagnosis of conjunctivitis were recruited from 12 general medical practices in the UK. 163 children were assigned chloramphenicol eye drops and 163 placebo eye drops. Eye swabs were taken for bacterial and viral analysis. The primary outcome was clinical cure at day 7; this was assessed from diaries completed by parents. All children were followed up for 6 weeks to identify relapse. Survival statistics were used for comparison, and analysis was by intention to treat. Findings Nine children were lost to follow-up (one in chloramphenicol group; eight in placebo group). Clinical cure by day 7 occurred in 128 (83%) of 155 children with placebo compared with 140 (86%) of 162 with chloramphenicol (risk difference 3·8%, 95% CI −4·1% to 11·8%). Seven (4%) children with chloramphenicol and five (3%) with placebo had further conjunctivitis episodes within 6 weeks (1·2%, −2·9% to 5·3%). Adverse events were rare and evenly distributed between each group. Interpretation Most children presenting with acute infective conjunctivitis in primary care will get better by themselves and do not need treatment with an antibiotic.
