Exploratory Analysis of APOE ε4-Stratified Associations Between Plasma Alzheimer's Biomarkers and Retinal Imaging Metrics in Cognitively Normal Adults.

Purpose Retinal imaging offers a noninvasive window into microvascular and neurodegenerative changes, yet its relationship to circulating plasma biomarkers of Alzheimer's disease (AD) remains incompletely understood. We evaluated associations between plasma AD biomarkers and retinal imaging metrics in cognitively norma...

Plasma Glial Fibrillary Acidic Protein and Neurofilament Light Chain Concentrations Are Inversely Associated with Retinal Microvascular Perfusion and Vessel Density in Cognitively Normal Individuals with Familial or Genetic Risk Factors for Alzheimer’s Disease

Background/Objectives: Evaluating noninvasive, accessible ocular and blood-based biomarkers could aid in early risk stratification and disease detection during the preclinical phase of Alzheimer’s disease. This study investigates associations between plasma biomarkers of neurodegeneration and retinal structural and mic...
