Abstract | PURPOSE: DESIGN: Double-masked, controlled, prospective clinical trial. METHODS: In an ophthalmology clinic in a general hospital in Manila, Philippines, 459 children (mean [SD] age 6.6 [6.6] years; range, 7 months-21 years) with acute conjunctivitis were studied. Infected eyes were cultured for bacteria and underwent immunofluorescent testing for Chlamydia trachomatis. Viral conjunctivitis was diagnosed if bacterial cultures were negative and diagnostic criteria were met. Subjects were alternated to receive povidone-iodine 1.25% or neomycin- polymyxin-B- gramicidin ophthalmic solution, one drop 4 times daily in the affected eye. Ocular inflammation was evaluated daily by the family or patient and weekly by an ophthalmologist. The main outcome measures were days until cured and proportion cured after 1 and 2 weeks of treatment. RESULTS: Despite adequate statistical power (power >80% for a 1-day difference and P <.05), there was no significant difference between treatment groups regarding the number of days to cure or proportion cured at 1 or 2 weeks whether caused by bacteria or virus (P =.133-.824 for the four comparisons). After 1 week of treatment, povidone-iodine cured marginally more chlamydial infections than the antibiotic (P =.057). By 2 weeks, fewer chlamydial infections were cured than those of viral or bacterial etiology (P =.0001). The younger the patient, the faster their conjunctivitis resolved (R = 0.13, P =.013). CONCLUSIONS:
