This prospective, controlled study was conducted to compare the effects of tracheal intubation and extubation on intraocular pressure changes and hemodynamic parameters in pediatric patients with and without glaucoma. The children were scheduled for intraocular surgery. Twenty children with normal intraocular pressure and 15 with glaucoma were studied. A standardized general anesthetic was administered to both groups. After five minutes of anesthesia, intraocular pressure, heart rate and noninvasive blood pressure were measured. These measurements were repeated 30 seconds and two minutes after tracheal intubation. Further measurements were taken before, and 30 seconds and two minutes after extubation. The increase in intraocular pressure after intubation was greater in the glaucomatous group than in the normal group. The increase in intraocular pressure was greater after extubation than intubation in both groups, but was similar in the two groups. However, because of the already increased intraocular pressure in glaucomatous children, they may be at an increased risk of visual damage after intubation and extubation.
