Design outcomes

Primary

MeasureTime frame
Main Objective: Does injection into the eye of ranibizumab prior to undergoing vitrectomy surgery improve vision in patients with proliferative diabetic retinopathy?;Secondary Objective: Does injecting ranibizumab into the eye before undergoing vitrectomy surgery for proliferative diabetic retionopathy: Make the surgery easier? Reduce the incidence of bleeding after the operation? Change the growth of new blood vessels in the retina? Alter the amount of retinal detachment present? Alter the blood flow to the macula? Additionally, the study seeks to establish the levels of the drug in the eye at an interval after injection and compare this with levels detectable in the blood.;Primary end point(s): Absolute visual acuity at 12 weeks following surgery.
