Brief Summary
To determine whether ranibizumab therapy before and after tube insertion for glaucoma surgeries can maintain the patency of the tube and prevent scar formation, and increase the chances for a successful procedure compared to observation.

Outcome Measures
Primary Outcomes (1)
Tube Success at 6 Months
Criteria for success at 6 months postoperatively was intraocular pressure (IOP) \< 18mmHg without the necessity for adjunctive medication for pressure or IOP \< 15mmHg with \<=1 adjunctive medication.
6 months
Secondary Outcomes (1)
Significant Ocular Adverse Events
6 months
Study Arms (2)
Ranibizumab
ACTIVE COMPARATORRanibizumab (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
Usual care
NO INTERVENTIONStandard of care Ahmed tube insertion for open-angle glaucoma without injections of Ranibizumab
Interventions
intravitreal injection of 0.5 mg ranibizumab 1 week prior to tube insertion and then monthly x 2 more injections
Eligibility Criteria
You may qualify if:
- ability to provide written informed consent and comply with study assessment for the full duration of the study.
- age ≥ 21
- diagnosis of glaucoma and determined to be candidate for therapy with tube insertion.
You may not qualify if:
- pregnant or lactating females
- Persons on oral contraceptives and women of child-bearing age
- prior enrollment in the study
- any conditions the investigator believes would pose a significant hazard to the subject if the investigational therapy were initiated
- participation in another simultaneous medical investigation or trial
- history of active inflammatory, infectious, or idiopathic keratitis precluding view of anterior segment structures
- previous injections of ranibizumab in either eye.
- Persons on Plavix (clopidogrel bisulfate) and coumadin
- Persons with uncontrolled high blood pressure
- Persons with renal or liver disease

Limitations and Caveats
IOP reduction may be attributable to cataract surgery instead of or in addition to ranibizumab use. Further studies, with larger sample size and longer follow-up, are needed to evaluate safety and potential efficacy of intravitreal ranibizumab.
