title: Use of 25-gauge vitrectomy in the management of primary rhegmatogenous retinal detachment.
abstract: OBJECTIVE
  To evaluate the anatomical and functional results of 25-gauge transconjuctival vitrectomy in the management of primary rhegmatogenous retinal detachment (RRD).
  
  
  METHODS
  A retrospective, noncomparative interventional case series including 131 consecutive patients who underwent 25-gauge transconjunctival vitrectomy for primary RRD repair was performed. Data concerning pre- and postoperative visual acuity and intraocular pressure (IOP), lens status, macular status, location of primary break, surgical time, postoperative inflammation, peri- and postoperative complications, and number of sutured sites were collected. Main outcome measures were anatomical success rate, postoperative visual acuity and IOP, and peri- and postoperative complications.
  
  
  RESULTS
  The success rate at 3 months was 92.4%. The visual acuity improved from 20/50 (range, 20/16 to light perception) to 20/32 (range, 20/200 to 20/16). Ten patients (7.6%) redetached after a mean follow-up time of 38 days (range, 21-53 days) because of the presence of proliferative vitreoretinopathy in 7 eyes (9.2%) or a new retinal tear in 3 eyes (3.9%). A lowered IOP between 6 mmHg and 10 mmHg (mean, 7.8 mmHg) was observed in 11 patients (8.4%). None had frank hypotony. None of the patients had choroidal detachment or endophthalmitis.
  
  
  CONCLUSIONS
  Good case selection was shown to ensure good outcomes with 25-gauge transconjuctival vitrectomy in the management of primary RRD.
