The etiology of diabetic retinopathy (DR) involves multiple factors and affects the retinal neurovascular unit (NVU). DR has a chronic low-grade inflammatory component, and understanding its mechanisms allows the development of new therapeutic strategies. This review article summarizes the latest research on the role of inflammation in DR and discusses the efficacy of current anti-inflammatory treatments.
The etiology of diabetic retinopathy (DR) is complex, multifactorial and compromises all the elements of the retinal neurovascular unit (NVU). This diabetic complication has a chronic low-grade inflammatory component involving multiple inflammatory mediators and adhesion molecules. The diabetic milieu promotes reactive gliosis, pro-inflammatory cytokine production and leukocyte recruitment, which contribute to the disruption of the blood retinal barrier. The understanding and the continuous research of the mechanisms behind the strong inflammatory component of the disease allows the design of new therapeutic strategies to address this unmet medical need. In this context, the aim of this review article is to recapitulate the latest research on the role of inflammation in DR and to discuss the efficacy of currently administered anti-inflammatory treatments and those still under development.
