Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Measurement and description of the intraocular pressure, measured with a hand-held applanation tonometer (Tonopen XL), prior to intubation, after intubation, after final positioning for the procedure, after positioning every 30min until opening of the Dura mater, after losing of cerebrospinal fluid, every 30min to the end of the procedure, before returning to supine position and after extubation. | — |
Secondary
| Measure | Time frame |
|---|---|
| Complete ophthalmological examination one day prior to procedure and 5 to 7 days after the operation including measurement of intraocular pressure by tonometry after Goldman and visual testing. | — |
