Microbiologic spectrum and susceptibility of isolates in acute postcataract surgery endophthalmitis: are they same as they were more than a decade ago?

Endophthalmitis is a severe and vision-threatening complication of intraocular surgeries like cataract surgery. Treatment of endophthalmitis includes vitreous tap/biopsy to identify the etiologic organisms and prompt initiation of broad-spectrum intravitreal antibiotics. The choice of initial broad-spectrum antibiotics is based on the susceptibility patterns of micro-organisms in a particular region. The purpose of the current study was to investigate the spectrum of organisms causing culture-proven acute postcataract surgery endophthalmitis and their antimicrobial susceptibilities at our centre between 2006 and 2013, and to compare the results with the previously published data from the same centre.1 This was a retrospective, non-comparative, consecutive case series. Microbiology records were reviewed of all the culture-proven, acute postcataract surgery endophthalmitis cases treated at L V Prasad Eye Institute, Hyderabad, India, between January 2006 and March 2013. Bacterial isolates were identified using Analytical Profile Index (API, Bio Meriux, France). The susceptibility was determined by the Kirby–Bauer disk diffusion method. …
