Abstract: A system for screening impairment of a subject includes an imaging device and a display connected to a controller, the controller configured to send a first eye test signal to the imaging device and a second eye test signal to the display to initiate an eye test, and further configured to receive an eye test feedback signal based on captured images of subject eye movement during the eye test. The controller is configured to send a first cognitive test signal to the imaging device and a second cognitive test signal to the display to initiate a cognitive test, and is further configured to receive a cognitive test feedback signal based on captured images of subject eye movement during the cognitive test. A balance sensor is connected to the controller, the controller configured to receive a balance test feedback signal from the balance sensor indicative of subject movement during a balance test.

Abstract: A portable ocular response testing device includes a portable housing, a plurality of lights for generating visible light within two eye spaces of the portable housing, a controller for operating the lights according to a prescribed pattern, and an imaging system to capture images of the eyes under varying lighting conditions to evaluate an ocular response of a user to the lighting conditions. In some instances, the portable device is used in the field of ophthalmology for complete assessment of optic nerve defects producing Marcus-Gunn pupil, detection and quantification of color blindness, and detection and follow up of eye abnormalities. In other instances, the device is adapted for screening of driving under influence (DUI) or Driving While Intoxicated (DWI) by performing multiple eye tests resulting in field screening of DUI or DWI cases.

Abstract: Disclosed herein is a pupillary response scanning device and methods for use in performing swinging flashlight test, brightness saturation test, color discrimination test, and color blindness test. The device may include: a housing configured to provide a first isolated eye enclosure for a first eye and a second isolated eye enclosure for a second eye of a patient; one or more visible light sources, one or more infrared light sources, one or more imaging devices in each isolated eye enclosure; and a control system that may be configured for manipulating the visible light sources, infrared light sources and the imaging devices.
