  • Publication number: 20230255480
    Abstract: The present application describes the addition of various feedback mechanisms including visual and audio feedback mechanisms to an ophthalmic diagnostic device to assist a subject to self-align to the device. The device may use the visual and non-visual feedback mechanisms independently or in combination with one another. The device may provide a means for a subject to provide feedback to the device to confirm that an alignment condition has been met. Alternatively, the device may have a means for sensing when acceptable alignment has been achieved. The device may capture diagnostic information during the alignment process or may capture after the alignment condition has been met.

  • Patent number: 11412928
    Abstract: An ophthalmic imaging system has a specialized graphical user interface GUI to convey information for manually adjusting control inputs to bring an eye into alignment with the device. The GUI provides additional information such as laterality, visual alignment overlay aids, and live video feeds. The system further applies automatic gain control to fundus images, synchronizes itself with other ophthalmic systems on a computer network, and provides an optimized image load and display system.

  • Patent number: 11395589
    Abstract: Ophthalmic imaging systems, particularly slit-scanning ophthalmo-scopes, are capable of characterizing refraction over the entire field of view of the system. Light from the light source of the system illuminates a region of the eye and the returning light is measured on a detector. The deviation of the location of the returning light from a predetermined location on the detector is measured. The deviation corresponds to the mismatch between the refractions of the imaging system and the eye. The light can be scanned across the full field of view to characterize the entire field. A second illumination source traveling along a second illumination path can be used to improve the characterization. The characterization can be of use for optimizing the focus of the instrument and for assessing the condition of the eye, including assessing myopia and astigmatism in the periphery.

  • Publication number: 20220160228
    Abstract: An ophthalmic imaging system provides an automatic focus mechanism based on the difference of consecutive scan lines. The system also provides of user selection of a focus point within a fundus image. A neural network automatically identifies the optic nerve head in an FA or ICGA image, which may be used to determine fixation angle. The system also provides additional scan tables for multiple imaging modalities to accommodate photophobia patients and multi-spectrum imaging options.

  • Patent number: 8427653
    Abstract: Frequency domain optical coherence tomography (FD-OCT) systems and methods are provided. Thereby, a first measurement and a second measurement is performed, wherein in the first measurement an object region is illuminated by measuring light having a spectrum with a first spectral width and in the second measurement the object region is illuminated with measuring light having a spectrum with a second spectral width, wherein the first spectral width is at least 10% greater than the second spectral width. Further, during the first measurement intensities of spectral ranges of light having interacted with the object and being superimposed with reference light are detected, wherein a width of these spectral ranges is greater than a corresponding width during the second measurement. Thus, switching an axial field of view of structural information of the object across a depth direction is enabled upon minimizing radiation damage at the object.
