Intraocular Pressure and Optic Nerve Sheath Diameter Changes in Laparoscopic Cholecystectomies

Intraocular Pressure and Optic Nerve Sheath Diameter Changes in Laparoscopic Cholecystectomies

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.

• Patients undergoing laparoscopic cholecystectomy
• American Society of Anesthesiologists (ASA) 1 or 2 physical status patients
