Abstract
A method and system are provided for detecting, characterizing and monitoring eye diseases and, particularly, optic nerve diseases, by determining the difference in relative brightness sensed by the two eyes. The method utilizes eyeglasses having a pair of cross-polarizing lenses selectively adjustable for blocking or admitting light into each eye. The patient observes an illuminated test object while looking through the eyeglasses at maximum luminance. By adjusting the relative polarization of the lenses for the eye in which the test object appears the brightest, while occluding the other eye, the amount of brightness sensed by that eye can be compared to the other eye. If there is a disparity in brightness-sense between the eyes within certain pre-established ranges, the nature of the eye disease can be detected and specifically characterized, and its progression or resolution can be monitored.
