Vascular and perfusion density in superficial capillary plexus of macula as a biomarker for appearance of diabetic retinopathy

Science, Engineering and Health Studies, 2023
Diabetic alteration of the retinal microenvironment causes damage to the retinal vessels. Biomarkers such as vessel density and perfusion density, measured using optical coherence tomography angiography (OCT-A), may help detect early signs of diabetic retinopathy (DR) and track disease progression.
