title: Clinical experience with the Baerveldt 250-mm2 Glaucoma Implant.
abstract: OBJECTIVE
  To report the intermediate-term results of the Baerveldt 250-mm2 Glaucoma Implant for treatment of adult glaucoma.
  
  
  METHODS
  Retrospective, noncomparative, interventional case series.
  
  
  METHODS
  One hundred eight adult patients (108 eyes) with glaucoma who received a Baerveldt 250-mm2 Glaucoma Implant.
  
  
  METHODS
  Implantation of the Baerveldt 250-mm2 Glaucoma Implant.
  
  
  METHODS
  Intraocular pressure (IOP), visual acuity, number of glaucoma medications, and surgical complications. Success was defined as IOP > or = 6 mmHg and < or = 21 mmHg (with or without antiglaucoma medications), without further glaucoma surgery, devastating complication, or loss of light perception attributable to drainage implantation.
  
  
  RESULTS
  Mean age was 63.8+/-16.5 years. Mean postoperative follow-up was 22.8 months (range, 0.2-84.9; interquartile range, 3.9-36.3). Mean preoperative IOP was 36.3+/-13.0 mmHg, on 2.9+/-1.1 antiglaucoma medications. The mean postoperative IOP at final visit was 15.8+/-7.6 mmHg (P<0.0001, paired t test), on 0.8+/-1.0 antiglaucoma medications (P<0.0001, Wilcoxon test). Kaplan-Meier success rates were 0.92 (6 months, n = 81), 0.88 (12 months, n = 75), 0.84 (18 months, n = 68), and 0.79 (24 months, n = 61).
  
  
  CONCLUSIONS
  The Baerveldt 250-mm2 Glaucoma Implant provides good intermediate-term success for the treatment of adult refractory glaucoma.
