| Ocular blood flow parameters | Preoperative | First week | First month | P |
| Ophthalmic artery | ||||
| PSV (cm/s) | 31.39±10.84 | 33.27±9.71 | 37.48±10.87 | 0.048a |
| EDV (cm/s) | 6.40±3.40 | 7.14±3.04 | 7.72±2.78 | 0.150 |
| RI | 0.80±0.08 | 0.80±0.04 | 0.80±0.05 | 0.969 |
| Central retinal artery | ||||
| PSV (cm/s) | 9.47±3.37 | 8.69±3.09 | 7.97±2.67 | 0.049a |
| EDV (cm/s) | 3.04±1.70 | 2.44±1.0 | 2.48±0.76 | 0.150 |
| RI | 0.69±0.10 | 0.70±0.10 | 0.66±0.09 | 0.406 |
| Posterior ciliary artery | ||||
| PSV (cm/s) | 17.95±6.88 | 20.08±8.55 | 17.88±8.04 | 0.969 |
| EDV (cm/s) | 4.32±2.0 | 5.17±2.42 | 4.83±2.30 | 0.391 |
| RI | 0.73±0.11 | 0.73±0.08 | 0.71±0.08 | 0.497 |
PSV: Peak systolic velocity; EDV: End diastolic velocity; RI: Resistivity index; aP<0.05 statistically significant.
