title: Infrared photographic measurement of pupillary effects of dichlorvos in Beagles.
abstract: Dichlorvos was given orally to Beagles at dose rates of 13.4, 27, and 40.5 mg/kg of body weight. Pupillary response to a single strobe flash was observed by using infrared cinematography. In dogs given the two larger dosages, the pupil contracted to a smaller size than it had been before treatment (base line) and recovered more slowly to base-line diameter.
