Table 1. Comparison of arterial and venous HypS_ox measurements and arteriovenous (AV) differences from 4 rabbits (2 albino and 2 pigmented).

Table 1	HypSox		AV Difference	P-Value
	Artery	Vein
Pigmented Rabbit 1a	87±9%	77±12%	10%	0.03
Pigmented Rabbit 1b	91±14%	80±7%	11%	0.04
Pigmented Rabbit 2	86±10%	90±9%	4%	0.14
Albino Rabbit 3	95±8%	87±8%	8%	0.04
Albino Rabbit 4	82±6%	78±4%	4%	0.18

First two rows (Pigmented Rabbit 1A and 1B) show data from two different parts of the same pigmented rabbit retina demonstrating the reproducibility of the measurement. All other measurements are from different rabbits. Peripheral retinal pigmentation did not significantly affect these measurements. P-values determined using paired, two-tailed, Student T-test.
