Brief Summary:
Laparoscopic surgery is a widely used alternative to open surgery; Advantages include reduced bleeding and pain intensity, shorter hospital stay, and improved cosmetic results.
Laparoscopic surgery involves the creation of a carbon dioxide (CO2) pneumoperitoneum to facilitate a clear surgical view, which can result in increased intracranial pressure (ICP).
Ultrasonographic measurement of optic nerve sheath diameter (ONSD) is a simple, non-invasive, yet reliable technique for ICP assessment.Ultrasonographic assessment of optic nerve sheath diameter (ONSD) has been proposed as a non-invasive measurement of intracranial pressure.

Detailed Description:
Ultrasonographic measurement of optic nerve sheath diameter (ONSD) is a simple, non-invasive, yet reliable technique for ICP assessment. Previous studies have demonstrated that ultrasonographic measurement of ONSD correlates with the degree of ICP and can detect intracranial hypertension in a variety of clinical settings.
It was planned to measure the optic nerve sheath throughout the surgery with the help of a linear ultrasound probe.
Ultrasonographically, in each measurement, the optic nerve sheath diameter (ONSD) was detected 3 mm behind the entry point of the optic nerve into the globe in both eyes. ONSD will be measured bilaterally 3 mm behind the papilla. It will be evaluated by transverse measurement for each optic nerve.
