Descriptive Measures for Each Study Group

	Controls (n = 81)	Glaucoma (n = 85)	P
Age, mean ± SD (years)	59.0 ± 10.7	61.2 ± 12.2	0.22
Eye (% right eye)	54.3	51.8	0.74
Sex (% male)	33.3	52.9	0.03
Cataract extraction before study (%)	3 (3.7)	15 (17.7)	0.003
SAP MD, mean ± SD (dB)	−0.96 ± 1.51	−3.82 ± 6.12	<0.001
SAP MD, range (dB)	−5.98–1.50	−30.63–1.19	—
SAP PSD, mean ± SD (dB)	1.84 ± 0.82	3.82 ± 3.75	<0.001
SAP PSD, range (dB)	1.05–6.93	1.02–16.11	—

Age, mean deviation (MD), and pattern standard deviation (PSD) for standard automated perimetry (SAP) were analyzed with t-tests, whereas eye, sex, and number of cataract extractions in the study eye before the study were analyzed with chi-square tests.
