Primary Outcome Measures:
- To evaluate the effect of ranibizumab on vitrectomy complications such as recurrent vitreous hemorrhage, postoperative retinal detachment rates, and development of intraoperative retinal breaks. [ Time Frame: 6 months ]
| Estimated Enrollment: | 40 |
| Study Start Date: | August 2007 |
| Estimated Study Completion Date: | August 2008 |
This is an open-label, Phase I/II study of multiple doses of intravitreally administered ranibizumab in patients with severe NPDR and PDR prior to, during, and after vitrectomy therapy.
40 subjects will be enrolled and randomized 3:1 to ranibizumab or vitrectomy alone. 30 consented, enrolled subjects will receive 3 intravitreal injections of 0.5 mg ranibizumab administered 1-3 weeks pre-procedure, intraoperatively, and 1 month post-vitrectomy.
