Abstract:
1. A system for inducing and measuring a consensual pupillary response in a subject comprising: an induction device structured to generate at least one stimuli, said at least one stimuli comprising a light source structured to transmit a visible light portion of an electromagnetic spectrum, said visible light portion comprising visible light wavelengths from about 400 to 700 nanometers, said induction device further structured to expose a primary eye of the subject to said at least one stimuli during a test cycle, said induction device also structured to shield the secondary eye of the subject from incident visible light stimulation during said test cycle, said at least one stimuli structured to induce a consensual pupillary response in a secondary eye of the subject as a result of said exposure of the primary eye to said at least one stimuli during said test cycle, said induction device comprising a stimuli adjustment assembly structured to permit variation of at least one parameter of said at least one stimuli, said at least one parameter comprising a preselected range of said visible light wavelengths, wherein each said preselected range of said visible light wavelengths corresponds to one of a plurality of visible colored light portions of said electromagnetic spectrum, said stimuli adjustment assembly disposed in an operative position between said stimuli and the primary eye of the subject and being structured to substantially limit transmittance of said visible light portion to said preselected range of said visible light wavelengths corresponding to one of said plurality of visible colored light portions, said induction device further comprising a stimuli control assembly structured to maintain at least one parameter of said at least one stimuli in a predetermined control range, and a monitoring mechanism structured to permit detection of said consensual pupillary response, wherein said detected consensual pupillary response is at least partially defined by a constriction of the pupil of the secondary eye in response to said exposure of the primary eye to said at least one stimuli, wherein a degree of constriction of the pupil of the secondary eye is substantially equal to a degree of constriction of the pupil of the primary eye.
