| rho | (p) | rho | (p) | |
| Age at surgery | 0.256 | (0.035) | − 0.178 | (0.20) |
| Refractive error | 0.264 | (0.031) | − 0.088 | (0.53) |
| Visual acuity (LogMAR) | 0.131 | (0.29) | − 0.060 | (0.67) |
| IOP | − 0.263 | (0.030) | − 0.020 | (0.89) |
| Cup/disc ratio vertical | 0.261 | (0.044) | 0.029 | (0.85) |
| Disc area | 0.370 | (0.004) | 0.024 | (0.87) |

| RNFL Thickness Inf | − 0.089 | (0.48) | 0.086 | (0.55) |
| OCT GSS score | 0.112 | (0.38) | − 0.042 | (0.78) |
The p-value p = 0.050* in the table indicates the significance of the corresponding test, that means p < 0.05.
aCorrelation coefficient: Pearson’s rho for bivariate gaussian distributions, otherwise Spearman’s rho.
bCorrelation test: Pearson’s method for bivariate gaussian distributions, otherwise Spearman’s method.
