OCT Biomarkers for Diabetic Retinopathy

NIH/NIDDK DP3 DK104397 PIs: Yali Jia, David Wilson

 

Diabetic retinopathy (DR), associated with long-term diabetes mellitus, is a leading cause of blindness in the US. Structural optical coherence tomography (OCT) has become the standard method for evaluating diabetic macular edema; however, fluorescein angiography (FA), which requires an invasive intravenous dye injection, is still needed to assess capillary dropout and confirm neovascularization. Recently, we have used a high-speed OCT system to make non-invasive functional measurements such as angiography, total retinal blood flow, and retinal arterial pulsatility. The goal of the proposed project is to improve these functional OCT-derived biomarkers and determine their roles in the early detection and
