Abstract: A method, system and device for detecting an ocular dysfunction with optic neuropathy, such as the glaucoma group of diseases. More particularly, one eye is exposed to a series of flashes, and the resulting pupillary reflexes of both eyes are measured. The pupillary reflexes can then be evaluated to determine if the ocular dysfunction is present. A device that includes at least one light source can be incorporated into a system for recording and evaluating the pupillary reflexes.

Abstract: In a signal processing circuit and method for increasing speech intelligibility, a receiving circuit may receive an audio signal detectable by a human. A gain amplifying circuit provides gain amplification of the audio signal. A shaping filter modifies the audio signal to be in phase with a second audio signal present at the receiving circuit and which is detected by the human unprocessed by the signal processing circuit. The shaping filter further differentially amplifies first and second speech formant frequencies to restore a normal loudness relationship between them. A feedback circuit controls the gain amplification in the gain amplifying circuit for enabling the signal processing circuit to substantially prevent regenerative oscillation of the amplified audio signal. Additionally, a signal tone may be injected into the signal processing circuit for automatically controlling the gain amplifying circuit.

Abstract: To determine a cataract or the degree of cataractogenesis in an eye of a patient, the patient views two lights juxtaposed, wherein each light comprises a mixture of two different wavelength lights. One of the lights is a fixed reference mixture, while the mixture of the other non-fixed light is varied until the patient observes less distinction between the two light mixtures in terms of brightness, hue or saturation. The luminance levels of the light components of both light mixtures for providing comparison and the ratio levels of the components are predetermined. Once a transition range is established from the comparison, the predetermined ratios are then related to respective ratios of a standardized group. Deviations between the ratios of the patient and the standardized group indicate the existence of a cataract and/or the degree of a cataract precursor formation.

Abstract: The invention provides a composition and method for reducing molecular defects in metastable tissue systems. Molecular defects represent spaces or vacancies in the structural order of the metastable system. The effect of molecular defects can be minimized such that the pre-defect order is preserved through the use of structure makers. These structure makers will then occupy the space or vacancy of the molecular defect, preserving the pre-defect order of the system. Lithium ions are a preferred structure maker.

Abstract: To determine a cataract or the degree of cataractogenesis in an eye of a patient, the patient views two lights juxtaposed, wherein each light comprises a mixture of two different wavelength lights. One of the lights is a fixed reference mixture, while the mixture of the other non-fixed light is varied until the patient observes a match between the two light mixtures in terms of hue, brightness and saturation. The luminance levels of the light components of the non-fixed mixture for providing the match and the proportionate levels of the two components are then determined. The shorter wavelength light of the non-fixed mixture is then substituted with a new wavelength light and the new mixture varied again until the patient observes a match as before. Alternatively, a polarization state of the shorter wavelength light is altered before determining a new mixture for obtaining a match.

Abstract: The invention provides a composition and method for reducing structural defects in metastable systems. Structural defects represent spaces or vacancies in the structural order of the metastable system, which can be restored to the predefect order through the use of structure makers. These structure makers will then occupy the space or vacancy of the defect, restoring the order of the system. Lithium ions are used as a preferred structure maker to reduce the structural defects that lead to cataract in a human lens.
