Design outcomes

Primary

Measure	Time frame
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.	—
