title: Nonpenetrating deep sclerectomy versus trabeculectomy in bilateral primary open-angle glaucoma.
abstract: OBJECTIVE
  To establish the efficacy and safety of nonpenetrating deep sclerectomy versus trabeculectomy in primary open-angle glaucoma.
  
  
  METHODS
  Prospective randomized trial.
  
  
  METHODS
  Thirty-nine patients (78 eyes) with bilateral primary open angle glaucoma were included in the study.
  
  
  METHODS
  Eyes were randomly assigned to receive deep sclerectomy in one eye and trabeculectomy in the other eye.
  
  
  METHODS
  Mean intraocular pressure (IOP), postoperative medications, visual acuity, success rate, and complications.
  
  
  RESULTS
  At 12 months, mean IOP reduction was 12.3 +/- 4.2 (sclerectomy) versus 14.1 +/- 6.4 mmHg (trabeculectomy) (P = 0.15), and an IOP </= 21 mmHg was achieved in 36 (92.3%) and 37 eyes (94.9%) (P = 0.9), respectively. Complications included three (7.7%) flat/shallow anterior chambers and one (2.6%) hypotony (trabeculectomy), whereas internal iris incarceration was encountered in two eyes (5.1%) (sclerectomy).
  
  
  CONCLUSIONS
  Deep sclerectomy may provide comparable IOP reduction with fewer complications in management of primary open angle glaucoma.
