Fractal Analysis of Retinal Microvasculature and Its Association with Cardiovascular Outcomes: A Systematic Review and Meta-Analysis - Summary - MDSpire
To evaluate the association between fractal dimension (FD) of retinal microvasculature and cardiovascular disease (CVD) risk through a systematic review and meta-analysis, highlighting its potential significance as a biomarker.
Approach:
Key Findings:
Fractal dimension (FD) is associated with various cardiovascular outcomes, including stroke and coronary heart disease, though the nature of these associations can be inconsistent.
The relationship between FD and CVD risk varies by vessel type (arterioles vs. venules) and specific CVD outcomes, with some studies reporting conflicting results.
Interpretation:
The findings suggest that retinal FD could serve as a potential biomarker for assessing CVD risk, though the relationship is complex and influenced by multiple factors, which may have implications for clinical practice.
Limitations:
Inconsistencies in study findings regarding the association between FD and CVD outcomes may limit the reliability of conclusions drawn.
Variability in methodologies for measuring FD across studies could impact the comparability of results.
Limited availability of high-quality, multivariate-adjusted risk estimates in some studies restricts the robustness of the findings.
Conclusion:
Retinal fractal dimension may be a valuable tool for evaluating cardiovascular risk, but further research is needed to clarify its role and the mechanisms underlying its associations with different CVD types, particularly focusing on specific methodologies and outcomes.
