| Measure | Description | Time Frame |
|---|---|---|
| Optic nerve sheath diameter 5 minutes after collar placement | During each evaluation with Optic nerve sheath diameter, at least three measurements were attempted from each eye. The ONSD was measured 3 mm behind the retina. All scans were performed using a 13-6 MHz linear-array probe and a high resolution optimization setting. | 1 day after |
