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
Detailed Description:

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.
