Evaluation of Contrast Sensitivity, Chromatic Vision, and Reading Ability in Patients with Primary Open Angle Glaucoma

Table 2

Descriptive and clinical data for 121 glaucoma patients classified into two groups according to disease severity (Hodapp-Parrish-Anderson criteria).

	Early defect ()	Moderate defect ()
	Mean ± SD	Mean ± SD
Age (years)			0.253
BCVA (decimal notation)			0.016
IOPb (mm Hg)			0.647
CDR			<0.001
MD (dB)			<0.001
PSD (dB)			<0.001
VFI (%)			<0.001
CP (µm)			0.239
Photopic pupil size (mm)			0.803

: level of statistical significance in comparison between groups using the Mann-Whitney nonparametric test. Bold text shows the statistically significant results ().
BCVA: best corrected visual acuity; IOPb: basal intraocular pressure; CDR: cup-to-disc ratio; MD, PSD, and VFI, mean deviation (MD), pattern standard deviation (PSD), and visual field index (VFI) obtained in the visual field using Humphrey 24-2 Swedish Interactive Threshold Algorithm Standard perimeter; dB: decibels; CP: corneal pachymetry; µm: micrometers; SD: standard deviation.
