Intraocular Pressure and Optic Nerve Sheath Diameter Changes in Laparoscopic Cholecystectomies

NCT03933254 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2021-12-03

No results posted yet for this study

Summary

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.

Conditions

  • Intraocular Pressure
  • Intracranial Pressure
  • Pneumoperitoneum

Interventions

DIAGNOSTIC_TEST

Intraocular pressure measurement via ocular tonometry

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.
