NCT00644280

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 COMPARATOR

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

Drug: Ranibizumab

Usual care

NO INTERVENTION

Standard 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

Also known as: Lucentis
Ranibizumab

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

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.
