Mean Values (±Standard Deviation) of Visual Field Indices for Normal, Glaucoma Suspect, and Glaucomatous Eyes

	Normal (n = 30)	Suspect (n = 165)	Glaucoma (n = 125)	Analysis of Variance Test
SITA
	(n = 10)	(n = 81)	(n = 78)
MD	−0.39 (1.00)	−0.98 (1.74)	−4.80 (5.62)	< 0.0001
PSD	1.98 (0.81)	2.06 (1.62)	4.64 (3.72)	< 0.0001
SWAP
	(n = 2)	(n = 25)	(n = 18)
MD	0.21 (0.74)	−3.48 (4.09)	−1.35 (2.63)	*
PSD	4.42 (1.87)	3.08 (0.86)	3.75 (1.23)	*
FDT
	(n = 18)	(n = 59)	(n = 29)
MD	−1.99 (2.34)	−1.76 (2.70)	−3.40 (3.69)	0.26
PSD	4.27 (1.08)	4.48 (1.60)	5.67 (2.39)	0.02

FDT = frequency doubling technology; MD = mean deviation; PSD = pattern standard deviation; SITA = Swedish interactive thresholding algorithm; SWAP = short wavelength automated perimetry.

^*Analysis of variance test not calculated because of limited number of normal subjects.
