  • Publication number: 20200085291
    Abstract: The present disclosure relates to an apparatus and method for quantifying visual fields of a subject. The apparatus includes a dome structure for accommodating at least a part of body of the subject within the dome structure, a projection device mounted on the dome structure configured to project at least one of light stimuli and an image on inner surface of the dome structure and to capture one or more responses of the subject to one of the projected light stimuli and the image. The apparatus further includes a processor configured to analyze the one or more captured responses of the subject to quantify visual fields of the subject.

  • Patent number: 10517475
    Abstract: The invention relates to an apparatus and a method therewith to quantify visual field in infants. The invention provides a novel solution to the unmet need of detection of defects in the visual field in infants and/or babies and providing an apparatus with a software framework to minimize the errors of recording the readings and increasing their precision and analyzing said results automatically using the software embedded in the system. Said apparatus to quantify visual field in infants comprise of a light projection device onto a dome-shaped hemispherical structure with an infra-red camera along with fixation lights, a means for monitoring responses of the subject during testing, a means for recording and analyzing the readings. Said means to detect and record the eye/head movement in the subject during testing comprises said infra red (IR) camera connected to a device wherein software application is embedded.
