This study investigates the hypothesis that ranibizumab injection given into the eye is a safe, efficacious and helping treatment option applied before surgical intervention of the proliferative diabetic retinal eye disorder.
This is a randomized, double blinded , controlled, two-center study assessing the feasibility, efficacy and safety of intravitreal ranibizumab injection applied as a preoperative adjunct treatment before vitrectomy surgery in severe proliferative diabetic retinopathy (PDR). Comparator arm consists of patients receiving standard vitrectomy alone with sham intravitreal injection preoperatively.
