<prompt> Intra ocular pressure rises inIntubation laryngoscopyLMAInfusion of IV propofolBag and mask ventilation  <response>: Laryngoscopy and intubation of trachea can dramatically increase intraocular pressure to a value as high as 40mm Hg.Administration of intravenous lignocaine prior to intubation has been found to prevent an increase in IOPIOP changes with LMA inseion are less than those following tracheal intubation.Refer: Morgan and Mikhails Clinical Anaesthesiology, 5th edition, pg no 325-331
