The purpose of this study was to quantitatively assess the pupillary light reflex (PLR) in normal and anesthetized dogs using a pupillometer. Eleven dogs (20 eyes) of various breeds were included. PLRs were measured with a handheld pupillometer in dim light before and during anesthesia. Anesthesia was conducted with atropine, xylazine and ketamine. Parameters of pupillometry included neurological pupil index (NPi), pupil size, percent of change (%CH), latency (LAT), constriction velocity (CV), maximum constriction velocity (MCV) and dilation velocity (DV). NPi, %CH, CV and MCV were significantly decreased during anesthesia compared with the pre-anesthesia data. The results suggest that atropine-xylazine-ketamine combination anesthesia depresses the PLR. Additionally, this study demonstrates the feasibility of the use of a pupillometer in dogs.

The objective of the study was to examine changes of intraocular pressure (IOP) undergoing anesthesia in Rhesus Macaques (Macaca mulatta) with Laser-induced Ocular Hypertension. Twenty male rhesus macaques (hypertensive glaucoma eye in OD; normal eye in OS) between 6 and 20 years of age were used for the study. The monkeys were anesthetized with ketamine hydrochloride (10 mg/kg intramuscularly) and 1% isoflurane and then IOP in both eyes was measured by a single investigator using a calibrated TonopenTM applanation tonometer (Mentor, Norwell, MA, U.S.A.). The mean IOP with ketamine anesthesia was 36.70 ± 12.04 (right eye: OD) and 15.88 ± 2.84 (left eye: OS). The mean IOP with isoflurane anesthesia was 19.98 ± 6.67 (right eye: OD) and 15.32 ± 2.15 (left eye: OS). Undergoing isoflurane anesthesia, the IOP of OD was significantly decreased. Conclusively, careful examination of IOP is required to prevent unexpected contraindication on glaucoma patient with isoflurane anesthesia.
