|Abstract:||PURPOSE: To compare the late complications in the Ahmed Baerveldt Comparison Study during 5 years of follow-up. DESIGN: Multicenter, prospective randomized clinical trial. METHODS: SETTING: Sixteen international clinical centers. STUDY POPULATION: Two hundred seventy-six subjects aged 18.85 years with previous intraocular surgery or refractory glaucoma with intraocular pressure of > 18 mm Hg. INTERVENTIONS: Ahmed Glaucoma Valve FP7 or Baerveldt Glaucoma Implant BG 101-350. MAIN OUTCOME MEASURES: Late postoperative complications (beyond 3 months), reoperations for complications, and decreased vision from complications. RESULTS: Late complications developed in 56 subjects (46.8 +/- 4.8 5-year cumulative % SE) in the Ahmed Glaucoma Valve group and 67 (56.3 +/- 4.7 5-year cumulative % +/- SE) in the Baerveldt Glaucoma Implant group (P=.082). The cumulative rates of serious complications were 15.9% and 24.7% in the Ahmed Glaucoma Valve and Baerveldt Glaucoma Implant groups, respectively (P=.034), although this was largely driven by subjects who had tube occlusions in. the 2 groups (0.8% in the Ahmed Glaucoma Valve group and 5.7% in the Baerveldt Glaucoma Implant group, P=.037). Both groups had a relatively high incidence of persistent diplopia (12%) and corneal edema (20%), although half of the corneal edema cases were likely due to pre-existing causes other than the aqueous shunt. The incidence of tube erosion was 1% and 3% in the Ahmed Glaucoma Valve and Baerveldt Glaucoma Implant groups, respectively (P=.04). CONCLUSIONS: Long-term rates of vision-threatening complications and complications resulting in reoperation were higher in the Baerveldt Glaucoma Implant than in the Ahmed Glaucoma Valve group over 5 years of follow-up|
