title: Treatment of vitreoretinal disorders in the developing world: indications and outcomes of vitreoretinal surgery in Nepal.
abstract: OBJECTIVE
  To examine the outcomes of vitreoretinal surgery for retinal disorders at Tilganga Eye Centre in Kathmandu, Nepal.
  
  
  METHODS
  Retrospective noncomparative case series.
  
  
  METHODS
  Records of 255 patients undergoing vitreoretinal surgery from December 2000 to January 2003 were reviewed.
  
  
  METHODS
  Demographics, diagnoses, duration of symptoms, vision, and examination findings were noted before and after vitreoretinal surgery.
  
  
  METHODS
  Postoperative data were categorized by surgery type and analyzed by anatomic success, symptoms, and visual acuity (VA).
  
  
  RESULTS
  Sixteen percent of patients had >6/60 vision preoperatively, and the mean duration of vision loss before presentation was 4.9 months. Major indications for surgery were retinal detachment (RD) (75%) and vitreous hemorrhage (19%). Anatomic success was achieved in 74.5% of patients. Postoperatively, 39% of patients experienced improved VA, with 33% obtaining >6/60 vision.
  
  
  CONCLUSIONS
  Despite prolonged duration of vision loss at presentation, vitreoretinal surgery in the developing world can restore useful vision in many patients with RD and vitreous hemorrhage.
