Abstract: A vision screening device for administering vision screening tests to a patient, and in particular vision screening test(s) to determine the presence of diseases and/or abnormalities in the eye(s) of the patient, is described herein. The vision screening device is used to determine an order for performing various vision screening exams selected by a clinician for a patient in a compact timeframe and reduce time needed for pupil recovery between exams or other delays. The vision screening device captures visible and near infrared reflections from the patient and generates a composite image used for generating suggested diagnoses to a clinician via a display of the vision screening device.

Abstract: A vision screening device for administering vision screening tests to a patient, and in particular vision screening test(s) to determine the presence of diseases and/or abnormalities in the eye(s) of the patient, is described herein. The vision screening device includes emitters for emitting near-infrared light and white light from a patient-facing side and includes a sensor to receive reflected light and energy for performing vision screening tests. The received reflected energy comes into ana emission surface and is reflected by a beam splitter to a sensor. The vision screening device includes a first display for displaying digital objects for a vision test and a second display for a clinician to interact. The vision screening device further includes a sensor to aid in proper positioning of a patient during screening.

Abstract: A vision screening device for administering vision screening tests to a patient, to determine the presence of diseases and/or abnormalities in the eye(s) of the patient, is described herein. The vision screening device may include associated methods and systems configured to perform the operations of the vision screening tests. The device may include a radiation source configured to generate near-infrared (NIR) radiation, a sensor configured to capture a grayscale image representing the radiation reflected by the eye(s) of the patient, a white light source, and a camera configured to capture a color image of the eye of the patient. The device may also be configured to generate a composite image based on the grayscale image and/or the color image, determine a difference between a value associated with the eye and an expected value, and generate an output indicative of a condition associated with the eye(s) based on the difference.

Abstract: A device for monitoring a physiological variable determines a starting value for a self-adjusting alarm limit based on an abnormal state of the physiological variable. The device determines a new value for the self-adjusting alarm limit from physiological data values received during a time window. When the new value for the self-adjusting alarm limit moves in a targeted direction, the device resets the self-adjusting alarm limit at the new value.

The device may then recommend action to prepare for such behavior, if necessary.

Abstract: Various implementations disclosed herein relate to systems, methods, and devices to facilitate mass vision screening of individuals. An example method includes capturing a first image of an individual and confirming an identity of the individual based on the first image. In response to confirming the identity of the individual, the method may further include capturing one or more second images of an eye of the individual; determining one or more health metrics of the individual based on the one or more second images, and transmitting, to a remote device, the identity of the individual and the one or more health metrics of the individual. The one or more health metrics may include at least one of a pupillary distance of the individual, a pupil size of the eye of the individual, a complete refraction of the eye of the individual, or an alignment indicator of the eye of the individual.

Abstract: An eye imager includes a camera having at least one infrared LED. The eye imager captures a sequence of infrared images of an eye using the camera. The eye imager selects an infrared image from the sequence of infrared images. The eye imager determines a cataract is detected in the infrared image and performs an action based on detection of the cataract.

Abstract: A vision screening device captures image(s) of reflected radiation from light source(s) and uses the images to determine a cornea curvature. The light source(s) may comprise infrared LEDs and be configured in a predetermined pattern. Based on the cornea curvature, an axial length is determined and/or a prescription for a patient is determined. Other characteristics of the patient may be used to determine axial length. Based on the axial length, a recommendation for the patient is generated and displayed.

Abstract: A patient monitoring device initiates an interval mode that includes measuring blood pressure at predetermined intervals over a predetermined period of time. The device takes a first blood pressure measurement at one of the predetermined intervals, and determines whether the first blood pressure measurement is abnormal. The device takes a second blood pressure measurement after a predetermined delay when the first blood pressure measurement is determined abnormal. The device compares the first and second blood pressure measurements to confirm whether the first blood pressure measurement is abnormal. The device triggers an alarm when the first blood pressure measurement is confirmed as abnormal.

Abstract: Methods and systems implement a pain assessment regularizing system to autonomously observe pained expressions and physiological measurements of a patient, in order to systematically collect data inputs which may be converted to pain assessment factors. The pain assessment regularizing system, by collecting this data, may combine it with clinical appraisals of pain intensity and patient self-reporting of pain intensity, weighing each factor appropriately in a manner sensitive to the progression of a patient care program, so as to lessen confounding effects of subjective pain assessment. The pain assessment regularizing system may generate a time series of regularized pain assessment factors, and further forecast a regularized pain assessment trend.
