Pressure-Dependent Changes in NFLT or a Percentage of NFLT to Total Retinal Thickness, Densities of Swollen Axons (Ax), and Damaged GCs and NDS

Condition (n)	NFLT ± SE (μm) [P]	NFLT ± SE (%) [P]	Ax ± SE (n) [P]	GC ± SE (n) [P]	NDS ± SE (n) [P]
10 mm Hg (5)	2.4 ± 1.3 [−]	1.5 ± 0.6 [−]	0.2 ± 0.5 [−]	0.5 ± 0.2 [−]	0.1 ± 0.1 [−]
25 mm Hg (5)	2.6 ± 1.2 [0.92]	1.7 ± 0.7 [0.96]	0.3 ± 0.7 [0.98]	0.6 ± 0.4 [0.89]	0.2 ± 0.1 [0.93]
50 mm Hg (5)	7.9 ± 4.2 [0.002]*	5.8 ± 1.7 [0.002]*	6.5 ± 4.6 [<0.001]*	7.5 ± 2.8 [0.002]*	0.8 ± 0.3 [0.010]*
75 mm Hg (7)	12.8 ± 3.7 [<0.001]*	9.2 ± 2.6 [<0.001]*	13.5 ± 4.3 [<0.001]*	8.8 ± 3.6 [0.002]*	0.9 ± 0.4 [0.009]*

The density of swollen axons was counted per 100 μm² of the NFL. The density of damaged GCs was counted per 500 μm of retina. Ps were calculated vs. the control (10 mm Hg) by Mann-Whitney U test.

^*Statistical significance was set at P < 0.05.
