| Temporal optic disc vessel density, % | 57.6±6.8 | 61.7±4.4 | 55.7±6.6 | 62.8±4.0 | 0.002a | 0.657b | <0.001b |
| Average parafoveal SCP vessel density, % | 50.1±3.0 | 51.0±3.9 | 49.6±2.3 | 48.3±2.4 | 0.015a | 0.015b | 0.085b |

Notes: Bold face indicates statistically significant p value. at-Test. bPost hoc test followed by analysis of covariance (ANCOVA) with gender as covariate. P1 Value = p value of PA versus controls. P2 Value = p value of preperimetric PA subgroup versus controls. P3 Value = p value of perimetric PA subgroup versus controls.
Abbreviations: PA, pituitary adenoma; SCP, superficial capillary plexus; DCP, deep capillary plexus.
