Core Tip
Core Tip: Diabetic retinopathy (DR) remains a leading cause of vision loss and blindness among individuals with type 2 diabetes. A critical need exists for reliable biomarkers that can facilitate early identification and diagnosis of DR, as the absence of such markers significantly impedes timely intervention and effective management. The study by Lin et al reveals that "IBIL levels are independently and inversely associated with DR risk, suggesting its potential as a low-cost, non-invasive, and readily applicable predictive biomarker". To facilitate a comprehensive understanding of this novel predictive indicator, this review first evaluates the potential of indirect bilirubin in DR risk prediction from both basic science and clinical perspectives. It subsequently addresses the advantages and challenges associated with its application as a predictive biomarker and concludes with projections on its future role in DR screening strategies.
