A combined anaesthesia with ketamine, urethane und propionylpromazine was performed on 30 cats for lengthy eye-surgery operations. This schedule of anaesthesia proved to be most advantageous because of the promt onset and the sufficient degree of anaesthesia, which could be maintained for hours without complications. Open manometric tonometry showed no raised intraocular pressure during the anaesthesia with a mean value of 27.6 mm Hg, which is within the normal range of IOP for cats.
