Retinal microvasculature parameters in healthy control subjects and in those who experienced a myocardial infarction (MI) at a young age (<50 years). All parameters were measured in both eyes. Measured values in the right eye and left eyes were compared using two-tailed paired t-tests.

	Right eye	Left eye	p
Healthy subjects
CRAE-6 (µm)	47.5 ± 2.0	46.9 ± 1.6	0.16
CRVE-6 (µm)	57.0 ± 1.8	56.8 ± 2.0	0.64
AVR	0.83 ± 0.04	0.83 ± 0.03	0.43
MI subjects
CRAE-6 (µm)	47.6 ± 2.2	46.9 ± 1.9	0.09
CRVE-6 (µm)	57.1 ± 2.0	56.6 ± 2.2	0.18
