  • Title: Electrically evoked direct and consensual reflexes of the pupil.
    Author: Tanino T, Kurihara K.
    Journal: Jpn J Ophthalmol; 1982; 26(4):462-7. PubMed ID: 7166904.
    Abstract:
    In 10 men with their ages ranging from 18 to 31 years, one eye was stimulated with alternating current using a contact lens electrode. Pupil constrictions elicited in both eyes were recorded by binocular infrared videopupillography. The pupil reflex evoked was named the electrically evoked pupillary reflex (EEPR). The time courses of the direct and consensual EEPR were similar; no significant differences were found between both reflexes in the amplitude of pupil constriction, the latency time, constriction or redilatation times. The time courses of the electrically evoked reflexes closely resembled those of the pupillary light reflexes, confirming the existence of common neural pathways.
