Summary Laparoscopic surgery carried out under general anaesthesia is associated with physiological changes, which also determine changes in intra‐ocular pressure. We measured intra‐ocular pressure at each phase of gynaecological laparoscopy, carried out under propofol‐alfentanil‐isoflurane general anaesthesia, in young women of ASA 1 status, with no pre‐existing eye disease. Measurements were made with a Perkins applanation tonometer. Mean arterial pressure and end‐tidal CO, tension were kept constant throughout the study. Intra‐ocular pressure decreased significantly after induction of anaesthesia, remained unchanged after a pneumoperitoneum of up to an intraperitoneal pressure of 15 mmHg had been created, increased significantly with head down tilt, but did not increase significantly above pre‐induction values. Adequate depth of anaesthesia compensated for the intra‐ocular pressure increase caused by head down position. Plateau airway pressure, considered as reflecting intrathoracic pressure, increased with intraperitoneal pressure elevation. However, such changes did not correlate with intra‐ocular pressure changes.
