title: Ocular hypothermia depresses the human pupillary light reflex.
abstract: Twelve human volunteers were studied to determine the effect of eye surface cooling on the parameters of the light reflex. Surface cooling resulted in a 38% decrease in the maximum constriction velocity and a 36% decrease in the maximum redilation velocity. These changes were thought to be the result of a "sluggish" response of the pupillary sphincter.
