Claim:
1. A method for determining the state of health of an eye using a pupillometer to provide an objective chromatic perimetry analysis test, wherein: the pupillometer comprises a processor, at least one camera, and a testing compartment provided in the form of a substantially hemispheric bowl; the substantially hemispheric bowl comprises a plurality of chromatic beam emitters arranged about a visual field forming a plurality of visual field testing points; the chromatic beam emitters generate a plurality of chromatic stimuli about the visual field testing points; the chromatic stimuli comprise a first chromatic beam stimulus and a second chromatic beam stimulus; at least one of the first chromatic beam stimulus and the second chromatic beam stimulus employs a wavelength that stimulates ganglion cells; the testing compartment further comprises a light adaptation emitter; the inner surface further comprises a fixation point opposite a subject's line of sight; the at least one camera records pupil contraction in response to the first and second chromatic beam stimuli; the processor controls the chromatic beam emitters and the stimulus parameters of the chromatic beam emitters; the processor processes data associated with and generated by the first and second chromatic beam stimuli and the camera; and the method comprises wherein (i) the first chromatic beam stimulus employs a shorter-wavelength chromatic beam, relative to the second chromatic beam stimulus, (ii) the second chromatic beam stimulus employs a longer-wavelength chromatic beam, relative to the first chromatic beam stimulus, and (iii) the wavelengths of the first chromatic beam stimulus and the second chromatic beam stimulus are selected from the visual spectrum spanning from about 390 nm to about 750 nm.
