  • Patent number: 9579052
    Abstract: A method and an apparatus for detecting change in retinal oxygen saturation over time are provided. The method includes the steps of capturing a first group of images of two or more wavelengths, calculating oxygen saturation of a vessel in the first group of images, storing the first group of images on a data storage device, capturing a second group of images of two or more wavelengths, calculating the oxygen saturation of a vessels in the second group of images, storing the second group of images on a data storage device, spatially registering the pair of the group of images, captured at different time and calculate the change in oxygen saturation. The method also includes means to validate whether an observed change in oxygen saturation is a real physiological change or artificial.

  • Publication number: 20120179486
    Abstract: The present invention discloses methods, computer program and system to overcome the limitation of the current clinical practice. This is achieved by using information technology and the vast amount of epidemiological data available to create algorithms that calculate the risk or severity profile of an individual with any given disease. The individual profile presents the current condition and/or position of the individual in comparison with the mean base curve of the total population and in accordance with upper and lower risk limits. The individual profile is then fitted with its optimal use of healthcare resources, such as medication, surgery, laser treatment, surveillance and follow-up, to optimize and individualize the health outcome of this individual, and at the same time optimize and individualize the allocation of healthcare resources within the system.
