[A modern perspective on the pathogenesis of proliferative diabetic retinopathy].

Abstract

This article reviews the pathogenic mechanisms underlying proliferative diabetic retinopathy (DR), focusing on the development of angio-fibrotic switch, neurodegeneration, pro-inflammatory and pro-angiogenic biomarkers, emphasizes the modern perspectives on the role of the vitreous body and mechanical traction in DR progression. Understanding of these pathogenic mechanisms will provide new opportunities for improvement and development of treatments for DR at earlier stages, before significant and persistent functional impairment occurs.
