Abstract
Dysregulation of angiogenesis can cause a disruption in oxygen and nutrient delivery, resulting in impaired neural retinal function. Understanding the underlying components involved in its pathophysiology is essential to develop new treatments for preserving and restoring vision. The aim of this review is to describe the role of angiogenesis in different retinal and choroidal pathologies and evaluate current and emerging anti-angiogenic therapies for retinopathies. Current research articles, focusing on the latest clinical trials from the last two decades, were used to write this review. We discuss normal angiogenesis, in contrast to pathological angiogenesis, in four diseases: retinal vein occlusion (RVO), age-related macular degeneration (AMD), diabetic retinopathy (DR), and retinopathy of prematurity (ROP). Alongside these diseases, this review discusses relevant anti-angiogenic therapies that have been approved for use and are under active investigation through clinical trials for their safety and efficacy.
