Clinical Report: Disruption of the Neurovascular Unit in Diabetic Retinopathy
Overview
Diabetic retinopathy (DR) is increasingly recognized as a neurovascular degenerative disorder, with early neuronal dysfunction preceding visible vascular lesions. This review discusses the molecular pathways involved in DR.
Background
Diabetic retinopathy is a significant cause of vision loss among adults, affecting over 100 million individuals globally. Traditionally viewed as a microvascular complication, recent insights reveal that DR involves interactions among neuronal, glial, and vascular components of the retinal neurovascular unit.
Data Highlights
No numerical data provided in the article.
Key Findings
Diabetic retinopathy is a neurovascular degenerative disorder, not solely a microvascular complication.
Chronic hyperglycemia and oxidative stress disrupt the retinal neurovascular unit, leading to neurovascular uncoupling.
Functional abnormalities in DR can occur before visible vascular lesions are detected.
Current therapies primarily target advanced disease.
Clinical Implications
Recognizing diabetic retinopathy as a disorder of the neurovascular unit may facilitate earlier diagnosis.
Conclusion
Reframing diabetic retinopathy as a neurovascular disorder emphasizes the importance of early detection.
An artificial intelligence–based optical coherence tomography pathway met noninferiority criteria for false-positive diabetic macular edema referrals and was associated with fewer referral decisions in a randomized clinical trial.
