CCT: central corneal thickness, DH: disc hemorrhage, ST: superior-temporal, TU: temporal-upper, TL: temporal-lower, IT: inferior-temporal, RNFL: retinal nerve fiber layer, C2-sup: average total deviation (TD) values of superior 2 points within central 5 degrees, r: correlation coefficient, β: standard partial regression coefficient, and CI: confidence interval. Values in bold are statistically significant () in the univariate regression analysis and statistically significant () in the multivariate regression analysis.
