Table 1.
Pre and postoperative measures of visual acuity, exophthalmos (measured by Hertel exophthalmometer), color vision (percent of identified Ishihara plates), mean deviation (MD), pattern standard deviation (PSD), and peripapillary retinal nerve fiber layer (PRNFL) thickness in different quadrants. P value shows the significance of each parameter changes after surgery.

| Average PRNFL thickness (microns) | 108 | 97 | <0.001 |
| Superior quadrant PRNFL thickness (microns) | 142 | 121 | <0.001 |
| Inferior quadrant PRNFL thickness (microns) | 152 | 129 | <0.001 |
| Nasal quadrant PRNFL thickness (microns) | 93 | 74 | <0.001 |

BCVA: Best corrected visual acuity; MD: Mean deviation; PSD: Pattern standard deviation; PRNFL: Peripapillary retinal nerve fiber layer; SD: Standard deviation.
