Tonography in the normal and glaucomatous beagle. 1977

K N Gelatt, and R M Gwin, and R L Peiffer, and G G Gum

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 minutes of Schiotz tonography of each eye. In dogs given a cepromazine (0.5 mg/kg intravenously) and then ketamine (10.0 mg/kg intramuscularly), the mean coefficient of aqueous humor out-flow in 24 normal Beagles was 0.24 mul/mm of Hg/minute (SD +/- 0.07). Mean coefficient of aqueous humor outflow in 35 glaucomatous Beagles, between 4 months to more than 37 months old, was 0.09 mul/mm of Hg/minute (SD +/- 0.04). Coefficient of aqueous humor out-flow was less in the older glaucomatous Beagle.

D004329 Droperidol A butyrophenone with general properties similar to those of HALOPERIDOL. It is used in conjunction with an opioid analgesic such as FENTANYL to maintain the patient in a calm state of neuroleptanalgesia with indifference to surroundings but still able to cooperate with the surgeon. It is also used as a premedicant, as an antiemetic, and for the control of agitation in acute psychoses.
