Association Between Pancreatic β-Cell Function and Quantitative OCT Angiography Metrics in Patients with Type 2 Diabetes Without Clinical Diabetic Retinopathy

The impaired pancreatic β-cell function is significantly associated with adverse macular vasculature alterations, suggesting that these vascular changes may occur prior to the clinical manifestation of DR in patients with compromised β-cell function. β-cell function markers might help identify patients at risk of early subclinical retinal microvascular changes.
