About this trial

This is an interventional treatment trial for Diabetic Retinopathy focused on measuring Severe proliferative diabetic retinopathy

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • male or female 18 or older who have signed an informed consent
  • Type I or II diabetes mellitus and severe proliferative retinopathy with tractional retinal detachment, tractional-rhegmatogenous retinal detachment, tractional detachment complicated with vitreous haemorrhage or active severe proliferative retinopathy not responding to previous panretinal laser photocoagulation
  • study eye BCVA must have at least light perception and must not exceed 70 letters using ETDRS at testing distance 4 meters
  • study eye vision decrease must be resulted from severe PDR

Exclusion Criteria:

  • History of uveitis
  • Uncontrolled glaucoma
  • High myopia
  • Any concurrent intraocular condition in the study eye that in the opinion of the investigator could confound the study results

  • History of vitrectomy within 60 days preceding Day 1 in the study eye
  • History of intraocular surgery within 30 days preceding Day 1 in the study eye
  • Untreated diabetes mellitus
  • Severe hypertension (systolic pressure higher than 160mmHg)
  • Current use of systemic medications known to be toxic to the retina
  • History of thromboembolic events (incl MI and stroke) within 5 years
  • Major surgery within previous 3 months or planned within the next 28 days
  • Known coagulation abnormalities or current use of anticoagulative medications other than aspirins
  • Known hypersensitivity to ranibizumab or any component of it
  • Women of childbearing potential unless 2 methods of birth control applied
  • Pregnant or lactating women

5. Study Description

Brief Summary
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.
Detailed Description
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.
