Characterization of the oculocardiac reflex during compression of the globe in Beagle dogs and rabbits.

Objective: This investigation characterizes the occurrence of oculocardiac reflex (OCR) in conscious rabbits and dogs by observing the effect of an ocular compression stimulus on heart rate (HR).

Animals Studied: Thirty-four clinically healthy adult rabbits and 15 clinically healthy adult Beagle dogs were studied.

Procedures: An electrocardiogram was used to record the heart rhythm and HR continuously.
