【 摘 要 】

References(12)Cited-By(1)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 variousbreeds were included. PLRs were measured with a handheld pupillometer in dim light beforeand during anesthesia. Anesthesia was conducted with atropine, xylazine and ketamine.Parameters of pupillometry included neurological pupil index (NPi), pupil size, percent ofchange (%CH), latency (LAT), constriction velocity (CV), maximum constriction velocity(MCV) and dilation velocity (DV). NPi,%CH, CV and MCV were significantly decreased duringanesthesia compared with the pre-anesthesia data. The results suggest thatatropine-xylazine-ketamine combination anesthesia depresses the PLR. Additionally, thisstudy demonstrates the feasibility of the use of a pupillometer in dogs.
