Table 3. Multiple regression analysis of independent variables affecting mean deviation in the study groups.

Variable Dependent	Independent	β	p Value
MD (dB)	Age (years)	-0.09	0.41
	AL (mm)	-0.09	0.43
	IOP (mmHg)	0.15	0.15
	CpRNFLT (μm)	0.70	<0.001
	Redox index	0.26	0.02
	ATI (AU)	0.20	0.07

β is the standard partial regression coefficient.

MD, mean deviation; AL, axial length; IOP, intraocular pressure; CpRNFLT, circumpapillary retinal nerve fiber layer thickness; redox index, the log GSH/GSSG ratio; ATI, acceleration time index; AU, arbitrary unit.
