  • Publication number: 20230248237
    Abstract: There is disclosed a method and system for retinal stimulation and retinal signal data collection. The system comprises a housing. The housing supports one or more light sources that are configured to expose a retina of an eye of an individual to a flash of light. The housing supports a spectrometer that is configured to record a light spectrum and an intensity of the flash of light. The housing supports a camera configured to capture image data of the eye while exposed to the flash of light.

  • Publication number: 20210386380
    Abstract: There is disclosed a method and system for generating retinal signal data. Calibration data corresponding to an individual may be received. A threshold impedance may be determined based on the calibration data. Retinal signal data corresponding to the individual may be received. The impedance of the circuit collecting the retinal signal data may be compared to the threshold impedance to determine whether the retinal signal data contains any artifacts. A portion of the retinal signal data corresponding to the artifacts may be removed from the retinal signal data.

  • Publication number: 20210298687
    Abstract: There is disclosed a method and system for predicting a likelihood that a patient is subject to one or more conditions. Retinal signal data corresponding to the patient may be received. Retinal signal features may be extracted from the retinal signal data. Descriptors may be extracted from the retinal signal features. The descriptors may be applied to a first mathematical model and a second mathematical model. The first mathematical model may correspond to a first condition. The second mathematical model may correspond to second condition. A first predicted probability for the first condition may be generated. A second predicted probability for the second condition may be generated. The first predicted probability and the second predicted probability may be output.

  • Patent number: 6677366
    Abstract: A method for reducing or preventing the effects of inflammation arising from injured tissue, which method comprises the steps of: a. bringing the injured tissue, or pre-injured tissue, into contact with a photosensitizing agent capable of penetrating into the tissue, resulting in the desired degree of biodistribution in less than one hour; and b. exposing the tissue thus contacted to light having a wavelength absorbed by the photosensitizing agent for a time sufficient to reduce or prevent inflammation in the exposed tissue, but not so long as to cause necrosis or erythema of the exposed tissue, or a pharmaceutical composition or an article for reducing or preventing the effects of inflammation arising from injured tissue. The composition comprises: a. from about 1 &mgr;g/mL to about 2 mg/mL of a photosensitizing agent capable of penetrating into the injured tissue, or pre-injured tissue, resulting in the desired degree of biodistribution less than one hour; and b. a pharmaceutically acceptable carrier.
