title: Postcataract endophthalmitis caused by Enterococcus faecalis.
abstract: OBJECTIVE
  To investigate the management strategies, susceptibility patterns, and visual outcomes of postcataract Enterococcus faecalis endophthalmitis.
  
  
  METHODS
  Retrospective chart review study of 26 eyes of 26 patients with culture-proven E. faecalis endophthalmitis.
  
  
  RESULTS
  In initial treatments, pars plana vitrectomy with intravitreal antibiotics in 15 eyes (58%). Resistance patterns among the isolates were the following: vancomycin in 0 of 26 eyes (0%), ampicillin in 0 of 26 eyes (0%), teicoplanin in 0 of 18 eyes (0%), and high-level gentamicin (minimum inhibitory concentration > 500 mg/L) in 8 of 12 eyes (67%). Presenting visual acuity ranged from counting fingers to no light perception. Final visual acuity was better than 5/200 in 4 of 26 eyes (15%), 5/200 to hand motions in 4 of 26 eyes (15%), and light perception to no light perception in 18 of 26 eyes (69%).
  
  
  CONCLUSIONS
  Although all E. faecalis isolates were susceptible to vancomycin, endophthalmitis caused by E. faecalis was usually associated with poor visual prognosis.
