Retinal microvascular complexity as a putative biomarker of biological age: a pilot study

Retinal microvascular complexity could be a promising new biomarker of biological age. Decreased box-counting fractal dimension was present in old patients, and this decrease was 2.1 times faster in participants who had age-related diseases (p=0.047).

Microvascular complexity measured by Box-counting fractal dimension (Db) and Sholl’s sum in healthy vs. unhealthy aging. Healthy aging model shown in black, unhealthy aging model shown in gray,
