Treatment of vitreoretinal disorders in the developing world: Indications and outcomes of vitreoretinal surgery in Nepal

Purpose: To examine the outcomes of vitreoretinal surgery for retinal disorders at Tilganga Eye Centre in Kathmandu, Nepal. Design: Retrospective noncomparative case series. Participants: 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. Main Outcome Measures: 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.
