Pneumoperitoneum created during laparoscopic surgeries has some effects on human physiology. Increased intraabdominal pressure results in increased intrathoracic pressure, and eventually may result in increased intracranial and intraocular pressures. In this study we aimed to identify intraocular and intracranial pressure changes during the perioperative period due to the pneumoperitoneum created for laparoscopic cholecystectomy surgeries. Intraocular pressure will be measured directly from the eye. Intracranial pressure will be estimated by measuring optic nerve sheath diameter changes ultrasonographically.

| Intraocular pressure measurement via ocular tonometry | Diagnostic Test | Intraocular pressure and optic nerve sheath diameter changes of the patients undergoing laparoscopic cholecystectomy will be measured throughout the surgery at different times using ocular tonometry and ultrasound, respectively. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Intraocular pressure | The normal physiological value for intraocular pressure is 10-20 mm Hg. It is affected by pneumoperitoneum created for laparoscopy. The pressure will be measured via ocular tonometry through the eye during the surgery at predetermined time intervals. | Throughout the operation (usually about 1 hour). |
| Measure | Description | Time Frame |
|---|---|---|
| Intracranial pressure | The normal physiological value for intracranial pressure is below 10 mm Hg. It is affected by pneumoperitoneum created for laparoscopy. The pressure will be estimated through changes in the optic nerve sheath diameter which will be measured by ultrasonography through the eye during the surgery at predetermined time intervals. | Throughout the operation (usually about 1 hour). |
