Portable, scanning, self-measuring pupillometers. With pupillometers described herein, cost effective and accurate central nervous system impairment can be quickly determined, thereby reducing worker inefficiency and improving safety. The pupillometers comprise eye orbit housings for positioning at least one eye orbit for scanning by the pupillometer, radiating diodes interfaced with the housings for irradiating at least one eye with scanning radiation, sensing elements adapted to receive reflected radiation from the eye irradiated by the radiating diodes, the sensing elements being further adapted to respond to a contrast between radiation reflected from the iris of the eye and radiation reflected from the pupil of the eye, and centering elements interfaced with the sensing elements for presenting an image of the pupil to a subject on the sensing elements so that the subject can center the image of the pupil on the sensing elements. |
