Abstract
The paper describes a newly developed method, called IRIS, for the recording of dynamic pupillary reflexes simultaneously in both eyes. The method is based on the principle of reflection of infra-red light by the iris/pupil boundary. IRIS incorporates a head-fixed. Maxwellian viewing-light stimulator driven by a function generator. IRIS enables pupillary constriction and dilation to be recorded in response to a pulsed light stimulus, thereby permitting determination of the latency times of constriction and dilation. Furthermore, the recording of natural pupil oscillations, the hippus, is possible. IRIS incorporates a clamp-box mode, permitting the study of stimulus-induced pupil oscillations and pupil cycle time. The compact and portable IRIS pupil system combines reliable and accurate recording with general versatility and ease of operation.
