Summary
This study established normative ranges for retinal vascular measurements in healthy individuals. These measurements, including caliber and complexity, correlate with age and blood pressure, offering insights into ocular and systemic health.
Area of Science:
- Ophthalmology and optometry
- Biomedical engineering
- Public health
Background:
- Retinal vascular parameters serve as potential biomarkers for ocular and systemic health.
- Establishing normative ranges is crucial for interpreting individual measurements and identifying deviations.
Purpose of the Study:
- To determine the normative range for a wide array of retinal vascular measurements.
- To assess the utility of these measurements as biomarkers for ocular and systemic health.
Main Methods:
- A cross-sectional study involving 10,151 healthy participants from the UK Biobank.
- Utilized Retina-based Microvascular Health Assessment System software to extract 114 retinal vascular measurements (caliber, complexity, density, branching angle, tortuosity) for arteries and veins.
- Explored associations between retinal measurements and health metrics like age, systolic blood pressure (SBP), body mass index, glycated hemoglobin, and intraocular pressure.
Main Results:
- Provided population normative ranges for 114 retinal vascular measurements, stratified by sex and age.
- Identified age and SBP as having the strongest associations with most retinal parameters.
- Observed decreases in central retinal artery equivalent, central retinal vein equivalent (CRVE), density, and complexity with increasing age and SBP, with arterial measurements showing greater changes.
Conclusions:
- Established population normative data for comprehensive retinal vascular measurements.
- Enables quantifiable approaches to better understand retinal vascular changes and their implications for health.
- Highlights the potential of retinal vascular measurements as biomarkers for systemic health assessment.
