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.
Claims20
A method of detecting an ocular dysfunction in a patient, the method comprising the steps of:
- exposing a first eye to a first series of flashes, wherein each flash in the first series of flashes varies chromatically from the other flashes;
- concurrently measuring pupillary reflexes of the first eye and a second eye of the patient during the exposing step;
- and
- evaluating the pupillary reflexes to determine if the ocular dysfunction is present.
A method of detecting an ocular dysfunction in a patient, the method comprising the steps of:
- exposing a first eye of the patient to a series of flashes generated by a first light source, wherein each flash in the series of flashes varies chromatically from the other flashes in the series of flashes;
- exposing a second eye of the patient to the series of flashes generated by a second light source;
- altering a luminosity of the first and second light sources;
- repeating the exposing steps using the altered luminosities;
- altering a location of the first and second light sources in the visual fields of the first and second eyes;
- repeating the exposing steps using the altered locations;
- concurrently recording pupillary reflexes of the first eye and the second eye during each exposing step;
- and
- evaluating the recorded pupillary reflexes to determine if the ocular dysfunction is present.
A system for detecting an ocular dysfunction, comprising:
- a first eye scope for exposing a first eye to a series of flashes and detecting a pupillary reflex of the first eye for each flash, the first eye scope having an ocular aperture, a light aperture, and a monitoring aperture;
- a second eye scope for detecting a pupillary reflex of a second eye for each flash, the second eye scope having an ocular aperture and a monitoring aperture;
- a first light source for generating the series of flashes through the light aperture, wherein each flash in the series of flashes varies chromatically from the other flashes;
- and
- a measurement system for concurrently measuring the pupillary reflexes of the first eye and the second eye based on light passing through the monitoring apertures.
