Calculating conjunctival redness

The present application includes methods, systems and computer readable storage devices for determining a color score for at least a portion of a biological tissue. The subject matter of the application is embodied in a method that includes obtaining a digital image of the biological tissue, and receiving a selection of a portion of the image as an evaluation area. The method also includes determining for each of a plurality of pixels within the evaluation area, a plurality of color components that are based on a Cartesian color space, and determining, from the color components, a hue value in a polar coordinate based color space. The method further includes determining a color value based on the hue value for each of the plurality of pixels, and assigning a color score to the evaluation area based on an average of the color values of the plurality of pixels.

09730578 · 2017-08-15 ·

A refraction device determines a refraction end point to provide corrective optics for a test subject. The device includes an adjustable optical system providing corrective optics to the test subject and an adjustable viewing target disposed along an optical path such as to be viewable through the adjustable optical system by a test subject. The adjustable viewing target includes a directional indicator linked synchronously to at least two choices of corrective optics presented to the test subject.

SYSTEM AND METHOD FOR THE TRAINING OF HEAD MOVEMENTS
20170156587 · 2017-06-08 ·

The invention relates to a system and to a method for training head movements of a person. Visual stimuli are generated with a visual stimulus generation device for a left and/or right eye of the person. Head movements of the person are captured with a measurement device. The head movement of the person captured with respect to a generated visual stimulus is assessed in a computational unit. Assessment information that is dependent on the assessment of the head movement captured with respect to a generated visual stimulus is then provided for the person with an output device.

FUNDUS IMAGING APPARATUS

A fundus imaging apparatus includes a scanning optical system, a control circuit, and an image forming unit. The scanning optical system scans a fundus of a subject's eye with light from a light source, and receives return light from the fundus by a light receiver. The control circuit controls the scanning optical system such that a scanning locus is formed by the light in the fundus. The image forming unit forms an image of the fundus based on a light receiving signal from the light receiver and a position of the scanning locus. The control circuit is capable of performing an alignment mode, in which the control circuit controls the scanning optical system to project an alignment indicator for aligning the scanning optical system with the subject's eye on the fundus based on the light from the light source.

Ophthalmologic information process system and ophthalmologic application
09554695 · 2017-01-31 · ·

Selection items which can be executed by an ophthalmologic application are displayed on a display portion on an ophthalmologic apparatus, and can be selected and executed by an operation portion on the ophthalmologic apparatus, thereby providing an ophthalmologic information process system and program which can reduce load on the operator and increase the overall throughput of examination. An ophthalmologic application transmits executable selection item information to the ophthalmologic apparatus and causes the ophthalmologic apparatus to display the information. Selection of one of the displayed selection items is executed by operation on the ophthalmologic apparatus. The behavior of the application is then controlled in accordance with the selection item.

DEVICE FOR MEASURING THE CHARACTERISTICS OF THE HUMAN EYE USING OCT TECHNOLOGY

A device for measuring the characteristics of the human eye with OCT technology, used for measuring eye properties, that has a light beam source with a low time coherence, a light beamsplitter used for dividing a single light beam coming from the light beam source into two and directing them towards the tested eye and the reference path and for directing the light beams that return from the reference path and from the tested eye, which enables the interference of those returning light beams and directing them further to the appropriate spectrometer, optical elements of the reference path and optical elements for directing the light onto the tested eye, a spectrometer with a collimator, a diffraction element, an optical lens and detector. The device has optical means for adjusting the spectrometer's imaging window by adjusting the spectral range of the wavelength recorded by the detector, which means are located within the spectrometer.

Automated determination of arteriovenous ratio in images of blood vessels

The methods and systems provided can automatically determine an Arteriolar-to-Venular diameter Ratio, AVR, in blood vessels, such as retinal blood vessels and other blood vessels in vertebrates. The AVR is an important predictor of increases in the risk for stroke, cerebral atrophy, cognitive decline, and myocardial infarct.
