Abstract:
A self-contained hand-held pupilometer for measuring pupillary response of a test subject to light stimulus, said pupilometer comprising:a hand-held sized binocular-type housing with two eyepiece locations laterally spaced at the back of said housing for positioning generally aligned with the subject's eyes;one of said eyepiece locations opening into and establishing visual communication with the interior of said housing;optical-electronic means located in said housing for (i) generating a pupillary response-inducing light stimulus, (ii) directing the light stimulus through said open eyepiece, and (iii) generating a signal indicative of the response of the pupil aligned with said open eyepiece location to said light stimulus;microprocessor-based control means located in said housing and operably connected to said optical-electronic means for (i) controlling the operation of said optical-electronic means, (ii) receiving and processing said signal, and (iii) storing pupillary response data generated therefrom; anda battery located in the housing connected to supply power to said optical-electronic means and said control storage means.
