title: Repair of primary rhegmatogenous retinal detachment using 25-gauge transconjunctival sutureless vitrectomy.
abstract: OBJECTIVE
  : To evaluate the anatomical and visual outcomes of primary rhegmatogenous retinal detachment repairs performed using 25-gauge transconjunctival sutureless vitrectomy.
  
  
  METHODS
  : A retrospective, noncomparative interventional case series including 53 consecutive eyes of 52 patients who underwent 25-gauge transconjunctival sutureless vitrectomy to repair primary rhegmatogenous retinal detachment was performed. Variables collected for the study were patient demographics, lens status, preoperative visual acuity, and macular status. Outcome measures included single-operation anatomical success rate, final anatomical success rate, postoperative visual acuity, and surgical complications.
  
  
  RESULTS
  : The retina was reattached with a single operation in 39 (74%) of 53 eyes. The final anatomical success rate was 100%. The mean time to redetachment was 72 days (range, 13-334 days). Proliferative vitreoretinopathy (64%) and development of new retinal breaks (43%) were the most common reasons associated with redetachment. Mean visual acuity improved from 20/100 to 20/60 (P = 0.001); 55% of eyes had final vision of 20/40 or better. Three eyes (6%) developed postoperative choroidal hemorrhage. Three eyes (6%) developed visually significant macular pucker that required surgery. No postoperative hypotony or endophthalmitis was observed.
  
  
  CONCLUSIONS
  : Repair of primary rhegmatogenous retinal detachments using 25-gauge transconjunctival sutureless vitrectomy resulted in excellent final anatomical success rate and postoperative visual outcomes. However, redetachments due to new tears and/or proliferative vitreoretinopathy resulted in a lower single-operation success rate than those reported with 20-gauge systems.
