The RAPDx is a novel, objective test of pupillary function which requires no patient response and no examiner subjective assessment. Approximately 15,000 data points are obtained in about 1 minute. Our patient was evaluated with the RAPDx. Above, note the reduced constriction of the pupils with stimulation of the RE as contrasted with stimulation of the LE.
RAPDx combines the series of detailed, macine-vsion observations of pupil responses to develop specific metrics to assess differential pupil responses. The RAPDx signature is not human observable.
