Active Comparator: Ranibizumab
Ranibizumab (0.5 mg in 0.05 mL) administered intravitreally at 3 time points: 9 days before Ahmed tube insertion for open-angle glaucoma, 1 month post-surgery, and 2 months post-surgery
intravitreal injection of 0.5 mg ranibizumab 1 week prior to tube insertion and then monthly x 2 more injections
Other Name: Lucentis
No Intervention: Usual care
Standard of care Ahmed tube insertion for open-angle glaucoma without injections of Ranibizumab
This is a randomized, open-label, Phase I/II study of intravitreally administered ranibizumab for the treatment of tube patency in glaucoma patients.
Thirty (30) patients with severe glaucoma requiring tubes will be randomized (2:1) to either ranibizumab or observation.
Consented, enrolled subjects assigned to the treatment group will receive open-label intravitreal injection of 0.5 mg ranibizumab 1 week prior to tube insertion and then monthly x 2 more injections Sham intravitreal injections for the observation group will NOT be performed.
Study start date: May 1st, 2007 (estimated) Enrollment period: 6-8 months (estimated) Follow-up period: 6 months Study end Date: December 1st, 2010 (estimated)
