The eye offers a unique, non-invasive window into systemic health, reflecting early signs of cardiovascular, neurological, metabolic, inflammatory, and oncologic disease.
This whitepaper explores how retinal imaging and ocular biomarkers can be used to detect and monitor chronic conditions such as hypertension, stroke, diabetes, Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, and cancer. It reviews key imaging modalities—including fundus photography, OCT, fluorescein angiography, and multimodal imaging—and explains how retinal microvascular changes correlate with disease progression throughout the body.
The paper also highlights the growing role of artificial intelligence and tear-based biomarkers in enhancing diagnostic accuracy and scalability. By positioning ophthalmic screening as a frontline tool for preventive healthcare, this work underscores the eye’s expanding role in early detection, risk stratification, and longitudinal disease monitoring.
