Elevated IOP Alters the Material Properties of Sclera and Lamina Cribrosa in Monkeys

Table 7

Initial rate and equilibrium rate of creep of ppSCl in axial direction (μm/min, Int: initial rate; Equl: equilibrium rate).

Groups	Creep rate (μm/min)
	Superior	Inferior	Nasal	Temporal
Exp. (Int.)						16.04	0.011
Ctrl. (Int.)						11.73	0.019
	0.037	0.009	0.047	0.048
Exp. (Equl.)						19.62	0.007
Ctrl. (Equl.)						7.66	0.039
	0.011	0.001	0.003	0.006

Creep rate of each scleral trip was measured for 3 times repeatedly. Paired-samples test was applied in the intergroup comparison in each quadrant; ANOVA method and post hoc test (LSD, Tukey HSD) were applied in the intragroup comparison in each group. The initial rate and equilibrium rate of each quadrant were lower in the experimental group than that in the control group, with significant difference (). The initial rate and equilibrium rate of each group were significantly different in each quadrant, respectively ().
