    Abstract: This document discloses both a method for visual field examination that makes it possible to perform eye sensitivity examinations and an instrument that is configured to perform said method for visual field examination. The method is based on absolute conditions, i.e. absolute differences in the differential luminous thresholds between symmetrical points with respect to the vertical meridian or the horizontal meridian are used; in this way, unlike with already-known methods, it is possible to study the symmetry and/or the harmony of the subjects themselves, without having to compare them to a reference population with all that this entails.

The optical measurement system receives from an operator, via a user interface of the optical measurement instrument, a begin measurement instruction indicating the start of a measurement period for objectively measuring at least one characteristic of the subject's eye. Subsequent to receiving the begin measurement instruction, the optical measurement system determines whether a criterion associated with the tear film quality of the subject's eye is not satisfied. In response to determining that the criterion is not satisfied, the optical measurement instrument takes one or more corrective actions to measure the characteristic of the subject's eye under a condition wherein the criterion is satisfied.

  • Patent number: 10041833
    Abstract: Provided is a system and method for active multispectral imaging having a transmitter that uses narrowband optical radiation to dynamically illuminate an object with modulated structured light in multiple spectral bands, and a receiver that includes an independent panchromatic imager. The transmitter and receiver can be operated in a bistatic decoupled configuration to enable passive multispectral synthesis, illumination-invariant sensing, optical communications, and the ability for the transmitter to emit a sequence of spectral bands in an order that is unknown to the receiver, and the receiver is able to passively decode the spectral identity from a band identifier embedded in the modulated structured light. The receiver passively decodes embedded high-bandwidth simplex communications while reconstructing calibrated multispectral images at video frame rates.

  • Patent number: 10028655
    Abstract: An optical system of an ophthalmologic imaging apparatus of embodiment splits light from a first light source into measurement light and reference light and detects interference light of returned light of measurement light from an eye and reference light. An image forming part forms an image based on detection result from the optical system. The optical unit includes a lens and joining member. The lens is locatable in an optical path of measurement light and used for changing a focus position of measurement light from a first site of the eye to second site. The joining member joins an optical path from a second light source to the optical path of measurement light. The optical unit converges light from the second light source having been guided into the optical path of measurement light by the joining member on an eye fundus via the lens.

  • Patent number: 10024649
    Abstract: An apparatus for optical coherence tomography (OCT) comprises a light source, a first arm, a second arm, and a processing unit. The first arm has a first dispersive optical assembly that induces a first amount of dispersion into light from the light source and traversing the first arm, where the first arm is one of a sample arm and a reference arm of an interferometer. The second arm has a second dispersive optical assembly that induces a second amount of dispersion into light from the light source and traversing the second arm, where the second arm is the other of the sample arm and reference arm. The second amount of dispersion is larger than the first amount of dispersion. The processing unit processes an interferometry signal to perform OCT, where the interferometry signal represents a superposition of the light from the first arm and the light from the second arm.

  • Patent number: 10004395
    Abstract: The technology described in this document can be embodied in systems and computer-implemented methods for determining a score representing an amount of staining of the cornea. The methods include obtaining a digital image of the cornea stained with a tracer material, receiving a selection of a portion of the image, and processing, by a processing device, the selection to exclude areas with one or more artifacts to define an evaluation area. For each of a plurality of pixels within the evaluation area, a plurality of Cartesian color components are determined and a hue value in a polar coordinate based color space is calculated from the components. An amount of staining of the cornea is then determined as a function of the hue value. The methods also include assigning a score to the evaluation area based on the amount of staining calculated for the plurality of pixels.

  • Patent number: 10004396
    Abstract: Ocular surface interferometry devices, systems, and methods are disclosed for imaging an ocular tear film. An imaging device can be focused on the lipid layer of the tear film to capture optical wave interference interactions of specularly reflected light from the tear film combined with a background signal(s) in a first image, wherein the specularly reflected light may be produced from various portions of the ocular tear film by obliquely illuminating various portions of the ocular tear film with a multi-wavelength light source, such as in a tiling pattern(s). The imaging device can also be focused on the lipid layer to capture a second image containing the background signal(s) present in the first image. The second image can be subtracted from the first image to reduce and/or eliminate the background signal(s) in the first image to produce a resulting image, which can used to measure a tear film layer thickness.
