Comparison of intraocular pressure (A) and ocular perfusion pressure (B) between groups. T1 = before anesthetic induction; T2 = before administration of the study drug; T3 = after administration of anesthetic induction agents; T4 = immediately after tracheal intubation; T5-T8 = 1, 3, 5, and 10 minutes after tracheal intubation; T9 = immediately after intraperitoneal CO₂ insufflation; T10 = immediately after steep Trendelenburg position; T11-T13 = 1, 2, and 4 h after onset of steep Trendelenburg position; T14 = just before supine position; T15, T16 = 10 and 30 minutes after supine position.

IOP = intraocular pressure, OPP = ocular perfusion pressure.
