Insights into Systemic Disease through Retinal Imaging-Based Oculomics.
Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing existing literature on retinal biomarkers without primary data or systematic review methodology.
PubMed 32704412 · doi:10.1167/tvst.9.2.6
What was done
This narrative review summarizes current evidence on high-resolution retinal imaging modalities (such as fundus photography) for identifying ocular biomarkers of systemic disease ("oculomics"), focusing on cardiovascular disease and dementia, and discusses the role of artificial intelligence and deep learning in risk stratification.
What was found
The abstract reports no numerical data, effect sizes, or performance metrics. It notes established population-based associations between retinal microvascular indices and screening for heart attack and stroke, as well as between neurosensory retinal structure and prevalent neurodegenerative disease, particularly Alzheimer's disease.
Why it matters
It highlights the potential for non-invasive, high-resolution retinal imaging combined with deep learning to serve as a scalable screening and risk-stratification approach for chronic complex disorders of aging.
Limits
The abstract contains no quantitative metrics, diagnostic accuracy values, or systematic literature search details. Because this is a narrative review, it does not provide new primary human data or formal meta-analytic synthesis.
