Name Time Method The day before surgery, an ophthalmologist examine the patient's vision, intraocular pressure, and fundus. On the day of surgery, the anesthesiologist measure intraocular pressure at after intubation, 5 minutes after prone position, 1 hour, 2 hours after intubation, the end of surgery, and reterning to the supine position. In patients who underwent laparotomy in the supine position as a control, intraocular pressure was measured on the day ofsurgery at intubation, 1 and 2 hours after intubation, after wound closure, and at the end of surgery.
