Comparison of characteristics among eyes of normal-tension glaucoma patients with unilateral optic disc hemorrhage (group A), fellow eyes without optic disc hemorrhage (group B), and eyes of normal-tension glaucoma patients without an episode of optic disc hemorrhage (group C)

*Comparison performed using Wilcoxon signed rank test
†Comparison performed using Mann-Whitney U test
‡Intraocular pressures measured on the day of contact lens ophthalmodynamometry
§As central retinal arterial pressure measurements were not conducted in 2 eyes from group B due to presence of spontaneous venous pulsation, only 20 eyes were included in the comparison between eyes in group B versus A or C.
Data are represented as mean ± standard deviation unless otherwise noted.
Significant values with P < 0.05 are in bold.
