About this trial

This is an interventional treatment trial for Complications of Diabetes Mellitus

Eligibility Criteria

18 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients with proliferative diabetic retinopathy who were scheduled for PPV for vitreous hemorrhage or tractional retinal detachment (TRD)

Exclusion Criteria:

  • Eyes with any pharmacologic intervention on study eye within 6 months
  • Eyes with panretinal photocoagulation on study eye within 3 months
  • Eyes with any pharmacologic intervention on fellow eye within 3 months,
  • History of ocular diseases other than diabetic retinopathy
  • History of PPV on study eye
  • History of systemic thromboembolic events including myocardial infarction and cerebrovascular accidents.

Experimental

Active Comparator

Arm Label

Intravitreal Avastin Day 2

Intravitreal Avastin Day 7

Arm Description

randomized to either treatment with preoperative IVB 2 days before PPV (Group A) or 7 days before PPV (Group B).

randomized to either treatment with preoperative IVB 2 days before PPV (Group A) or 7 days before PPV (Group B).

Outcomes

Primary Outcome Measures

intraocular VEGF levels (pg/ml) in both groups (measured in aqueous humor), using multiplex beads immunoassay
Because we want to compare the differences between day 2 and day 7, vitrectomy will be performed at day 2 in group 1 and day 7 in group 2. That's why the time frame has two time point

5. Study Description

Brief Summary
Purpose: To evaluate the acute changes in intraocular cytokines after intravitreal bevacizumab (IVB) in proliferative diabetic retinopathy. Design: Prospective, open-label, controlled, randomized interventional clinical trial. Participants: Twenty eyes of 28 consecutive patients who are scheduled for pars plana vitrectomy (ppV) for proliferative diabetic retinopathy were prospectively enrolled. Methods: All patients were randomly assigned to receive IVB either at 2 or 7 days before ppV. Aqueous humor samples were taken from anterior chamber just before IVB and at the time of surgery. Multiplex cytokine array were used to assay various cytokines
