  • Patent number: 10314474
    Abstract: Methods, systems, and computer readable media for predicting early onset glaucoma via structural parameters obtained via time and spectral-domain optical coherence tomography (SD-OCT) are disclosed. SD-OCT technology measures the thicknesses of the layers of the retina that contain the cells that die in glaucoma before there is any functional loss. A multivariable predictive model may be used for the diagnosis of early glaucoma using a combination of optic nerve head (ONH), peripapillary retinal nerve fiber layer (RNFL), and macular ganglion cell-inner plexiform layer (GCIPL) parameters measured via SD-OCT. The model generates a glaucoma probability score for individual patient, which is valuable information in assisting clinicians in glaucoma diagnosis and treatment.

  • Patent number: 10314482
    Abstract: An eye alignment monitor and method are described for the detection of variability of the relative alignment of the two eyes with each other, thereby detecting deficits of binocular function, for use as a screening device for these abnormalities especially in infants and young children. Each embodiment includes means for tracking of the positions of a subject's two eyes simultaneously, and furthermore includes repetitive calculation of the relative positions of the two eyes with respect to each other. The embodiments do not require fixation by either eye on a specific point. Typically, a movie on a video display is used for viewing by the subject. Variability of relative alignment of the two eyes with each other is typically determined by variability of the relative positions of images of the pupils of the eyes with respect to each other over time.

  • Patent number: 10314480
    Abstract: An ophthalmologic imaging apparatus includes a data acquisition unit and a controller. The data acquisition unit is configured to repeatedly acquire data by repeatedly scanning an eye using optical coherence tomography. The controller is configured to perform first control to adjust optical path length difference between a sample arm and a reference arm of an interference optical system for optical coherence tomography to place an image of the eye in a reference position in an image frame based on the data repeatedly acquired by the data acquisition unit. Further, the controller is configured to perform second control to change the optical path length difference so as to place the image of the eye in a new reference position in the image frame based on the data repeatedly acquired by the data acquisition unit. The apparatus can perform preparatory operations for OCT measurement of the subject's eye.

  • Patent number: 10288407
    Abstract: Apparatus and methods are described for optically analyzing an object having a plurality of layers, without needing to use a reference mirror. An extended broadband light source produces light, and directs the light toward the object, such as to create respective images of the light source on the respective layers of the object. An imaging system gathers light that is reflected from a point of the object into a conjugate point in the detector. The detector determines the thicknesses of the plurality of layers at the point of the object by analyzing, within the gathered light, interference between light reflected from the plurality of layers of the object at the point. Other applications are also described.

  • Patent number: 10278578
    Abstract: A therapeutic methodology for improving eye contact in children with ASD. A plurality of pairs of contact lenses is provided to an adult, typically a therapist or a parent of a child, where the contact lenses have an image of a subject of interest to the child imprinted on the contact lens. The plurality of the pairs of contact lenses provides a series of pairs of contact lenses where the image is gradually faded. An adult interacting with the child begins by wearing contact lenses having an image of greatest intensity. Through a series of therapy sessions with the therapist uses the contact lenses, as the child's duration and frequency of eye contact improves, the therapist will then use lenses with the image of the subject of interest to the child that are gradually faded. When therapeutic goal of the targeted duration and frequency of eye contact is reached, therapy using the contact lenses can be terminated.
