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 ret...

Retinal and Choroidal Structure and Microvasculature in Dementia With Lewy Bodies and Alzheimer Disease

Purpose: To compare retinal and choroidal structural and microvascular imaging parameters between patients with dementia with Lewy bodies and those with Alzheimer disease using optical coherence tomography (OCT) and OCT angiography (OCTA). Methods: In this cross-sectional study,...
