The bolded values were the statistically significant values (with p < 0.05).
CCT = central corneal thickness; D = diopters; dB = decibels; DH = disc hemorrhage; IOP = intraocular pressure; MD = mean deviation; SD = standard deviation.
Data are mean ± SD for continuous variables and frequency count (%) for categorical variables. Severity of glaucoma was classified based on visual field MD.
