Incidence of conjunctival colonization by bacteria capable of causing postoperative endophthalmitis

Increased awareness of the range of pathogens capable of causing postoperative endophthalmitis prompted a study of the conjunctival flora in 100 patients admitted for intraocular surgery. Bacteria capable of causing endophthalmitis were present in 74% of these patients, a much higher proportion than previously documented. No correlation was found with blockage of the nasolacrimal duct.
