title: Treatment outcomes in the tube versus trabeculectomy study after one year of follow-up.
abstract: OBJECTIVE
  To report one-year results of the Tube Versus Trabeculectomy (TVT) Study.
  
  
  METHODS
  Multicenter randomized clinical trial.
  
  
  METHODS
  
  
  
  METHODS
  17 Clinical Centers.
  
  
  METHODS
  Patients 18 to 85 years of age who had previous trabeculectomy and/or cataract extraction with intraocular lens implantation and uncontrolled glaucoma with intraocular pressure (IOP) > or =18 mm Hg and < or =40 mm Hg on maximum tolerated medical therapy.
  
  
  METHODS
  350 mm(2) Baerveldt glaucoma implant or trabeculectomy with mitomycin C (MMC).
  
  
  METHODS
  IOP, visual acuity, and reoperation for glaucoma.
  
  
  RESULTS
  A total of 212 eyes of 212 patients were enrolled, including 107 in the tube group and 105 in the trabeculectomy group. At one year, IOP (mean +/- SD) was 12.4 +/- 3.9 mm Hg in the tube group and 12.7 +/- 5.8 mm Hg in the trabeculectomy group (P = .73). The number of glaucoma medications (mean +/- SD) was 1.3 +/- 1.3 in the tube group and 0.5 +/- 0.9 in the trabeculectomy group (P < .001). The cumulative probability of failure during the first year of follow-up was 3.9% in the tube group and 13.5% in the trabeculectomy group (P = .017).
  
  
  CONCLUSIONS
  Nonvalved tube shunt surgery was more likely to maintain IOP control and avoid persistent hypotony or reoperation for glaucoma than trabeculectomy with MMC during the first year of follow-up in the TVT Study. Both surgical procedures produced similar IOP reduction at one year, but there was less need for supplemental medical therapy following trabeculectomy with MMC.
