Purpose: To analyze the emergence of multidrug-resistant Staphylococcus epidermidis after repeated conjunctival exposure to topical macrolide or fluoroquinolone antibiotics.Design: Prospective, controlled, longitudinal study with 1-year follow-up.Participants: Forty-eight eyes of 24 patients undergoing serial unilateral intravitreal (IVT) injections for choroidal neovascularization.Methods: Subjects received 4 consecutive monthly unilateral IVT injections and then were treated as needed. Each subject was assigned randomly to 1 of 4 antibiotics (azithromycin 1%, gatifloxacin 0.3%, moxifloxacin 0.5%, ofloxacin 0.3%) and used only their assigned antibiotic after each injection. Conjunctival culture specimens of the treated and untreated fellow eye (control) were obtained at baseline and after each injection. All bacterial isolates were tested for antibiotic susceptibility to 16 different antibiotics using the Kirby-Bauer disc diffusion technique.Main Outcome Measures: Antibiotic susceptibility patterns and multidrug resistance of S. epidermidis.Results: After 4 consecutive treatments, a total of 58 isolates of S. epidermidis each were isolated from control and treated eyes. Resistance to 3 or more antibiotics was present in 69% of S. epidermidis isolated from control eyes compared with 90% from treated eyes (P
