  • Publication number: 20210236743
    Abstract: Provided is a device for injection into an interlayer of an organ of a subject. The device includes a needle having a size transitional portion terminating in a sharp needle distal tip. The device also includes an elongated tissue separator that is shiftable in the needle lumen. An actuator shifts the tissue separator in the needle lumen between a first position, in which the separator distal tip is fixedly positioned proximally to the needle distal tip, and a second position in which the separator distal tip is fixedly positioned a predetermined distance distally from the needle distal tip.

  • Patent number: 11076757
    Abstract: A system and method for determining a state of health of an eye using a pupillometer is provided comprising an ocular fixture, a testing compartment, a camera, and a controller. The testing compartment comprises a plurality of chromatic beam emitters arranged about a visual field. The ocular fixture is positioned to facilitate exposure of light sensitive ocular structures of the eye to a chromatic stimuli. The camera is positioned to record temporal pupil responses of the eye. The controller controls emission wavelength, intensity, and duration of the chromatic beam emitters. The controller processes temporal pupil response data to generate signals representative of the eye positioned at the ocular fixture in response to the chromatic stimuli at a plurality of locations in the visual field. The method comprises driving the chromatic beam emitters with the controller to generate signals using chromatic stimuli and determining the state of health of the eye.

  • Patent number: 10264962
    Abstract: A pupillometer system includes a computer, a camera, and a testing compartment provided in the form of a substantially hemispheric bowl, where the substantially hemispheric bowl includes a plurality of chromatic beam emitters arranged about a visual field forming a plurality of visual field testing points. The plurality of chromatic beam emitters generate a first chromatic stimulus that stimulates a first anatomical structure of an eye and a second chromatic stimulus that stimulates a second anatomical structure of the eye where the first anatomical structure is different than the second anatomical structure. The camera records a pupil response of one or more eyes. The computer generates quantitative pupillary light reflex (PLR) measurements of the PLR in response to the stimuli, determines at least one PLR response ratio, and determines a state of health of the one or more eyes utilizing the at least one PLR response ratio.
