Summary

The purpose of this study is to determine the effect of anti-VEGF drug (Avastin) adminstration in eyes prior to surgical treatment for Traction retinal detachment (TRD) in patients with Proliferative Diabetic Retinopathy (PDR).

Clinical Details

Official title: Effect of Pre-operative Adjunctive Anti-VEGF on Growth Factors in Severe Proliferative Diabetic Retinopathy Requiring Surgical Management

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment

Primary outcome: The effect of an anti-VEGF agent, bevacizumab, on growth factor levels in eyes with traction retinal detachment due to PDR.

Secondary outcome:

To determine whether intra- and post-operative complications are decreased in eyes given pre-operative adjunctive bevacizumab in eyes undergoing PDR surgery.

Visual outcomes are improved in patients given pre-operative adjunctive bevacizumab in eyes undergoing PDR surgery.

Detailed description: Traction retinal detachment (TRD) due to proliferative diabetic retinopathy is a blinding disease caused by contraction of fibrovascular proliferation, treatment of which is limited to surgery. Fibrosis and neovascularization are both associated with high levels of connective tissue growth factor (CTGF) and vascular endothelial growth factor (VEGF) in the eye. Small, nonrandomized studies have suggested that pre-operative adjunctive anti-VEGF administration may reduce intra- and post-operative complications and provide visual benefit in patients with this condition.

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.
