Microbiological Diagnosis and Treatment

Prognosis of postcataract infectious endophthalmitis is at least partially dependent on the causative pathogen. In the EVS, bacteria were isolated in 69% of postcataract endophthalmitis cases and were gram positive in 94.2% of cases, most commonly Staphylococcus epidermidis, followed by other gram positives, gram negatives, and polymicrobial infections.[11] More recent series have mostly found lower culture positivity rates, ranging from 33 to 56%.[16,40–42] Samples in the EVS were obtained either by single port vitrectomy or needle aspiration, whereas recent studies only used needle aspiration.[11] Aqueous samples appear to be significantly less sensitive with reported culture-positive rates of 22 to 42%.[11,43,44]
