Abstract
A standard procedure for tonography was developed in the dog. Acepromazine, ketamine, xylazine, droperidol-fentamyl and combinations of these drugs were evaluated for effects on blood pressure, intraocular pressure and restraint of the dog for 4 min of Schiotz tonography of each eye. In dogs given acepromazine (0.5 mg/kg i.v.) and then ketamine (10.0 mg/kg i.m.), the mean coefficient of aqueous humor outflow in 24 normal beagles was 0.24 .mu.l/mm of Hg per min (SD .+-. 0.07). Mean coefficient of aqueous humor outflow in 35 glaucomatous beagles, between 4 mo. to more than 37 mo. old, was 0.09 .mu.l/mm of Hg per min (SD .+-. 0.04). Coefficient of aqueous humor outflow was less in the older glaucomatous beagle.
