title: Clinical profile and visual outcome following pars plana vitrectomy in acute post-operative endophthalmitis.
abstract: BACKGROUND
  Endophthalmitis following cataract surgery is a rare but devastating ocular complication where delay in treatment not only results in vision loss but also in difficulty to save the eye ball.
  
  
  OBJECTIVE
  To explore the clinical profile and visual outcome following pars plana vitrectomy (PPV) in acute endophthalmitis after cataract surgery.
  
  
  METHODS
  This is a retrospective interventional case series study conducted at Tilganga Institute of Ophthalmology (TIO), Nepal. All consecutive cases of acute endophthalmitis following cataract surgery treated with PPV from January 2005 to August 2010 were included in the study.
  
  
  RESULTS
  There were a total of 34 cases (34 eyes) treated with PPV. The age range was 8 - 93 years with mean age of 56.9 ± 19.5 years. The mean duration of presentation and duration following cataract surgery was 7.7 ± 8.1 days and 13 ± 11.6 days respectively. Small incision cataract surgery was done in 75 % of cases followed by phacoemulsification (15.6 %). The mean duration of the last follow -up was 4.3 months. Vision was improved in two-thirds of cases (67.67 %) with a good vision of 6/18 or better in 17.6 %. Among the available vitreous samples of 22 cases, 36.36 % had an abnormality in Gram and Giemsa stains and culture was positive in 13.6 % of cases.
  
  
  CONCLUSIONS
  Despite the late presentation, the majority of eyes were salvaged with improvement of vision in 67.67 %, with a good vision of 6/18 or better in 17.6 4 % of cases following PPV in acute post operative endophthalmitis.
