The device for screening for bioactive materials using the visual recognition of animals according to the present invention includes: an accommodating member (100) in which animals administered with a candidate bioactive material are accommodated; an imaging member (200) which captures images of the animals; and a detecting member (300) which reads the images in order to detect the visual recognition reactions of the animals. According to the method of the present invention for screening for bioactive materials using visual recognition of animals, the animals are administered with the candidate bioactive material, and the visual recognition reactions of the animals are detected.

Some demonstrative embodiments include apparatuses, systems and/or methods of determining one or more parameters of a refractive error of a tested eye. For example, a computing device may be configured to process depth mapping information to identify depth information of a tested eye; and to determine one or more parameters of a refractive error of the tested eye based on the depth information of the tested eye.

An ophthalmologic imaging apparatus includes: a first optical system that applies an accommodation stimulus to a subject's eye; a tomographic image forming unit that includes a second optical system that splits light from a light source into signal light and reference light, and detects interference light between the signal light having travelled via the subject's eye and the reference light, and creates a tomographic image of the subject's eye based on a detection result of the interference light; and an analyzer that compares a first tomographic image with a second tomographic image to acquire change information indicating a change in a tissue of the subject's eye due to an accommodation stimulus change. The first and second tomographic images are respectively created by the tomographic image forming unit for the subject's eye, to which first and second accommodation stimuli are respectively applied by the first and second optical systems.

The present invention relates to aids or devices with optical elements which include a partially reflective surface, which allow examination or recordal of a patient who is fixated on a visual target, with said examination or recordal occurring along the same axis as the line of sight. The invention also allows for a target more personalised and customised to the patient's needs.

A method of determining that an absence of suspicion of neurological injury is indicated in a subject is disclosed. The method involves prompting the subject to engage in three or more of the following neurological assessments: a) Reading Saccades, b) Near/far accommodation using Hart charts of different font sizes; c) Brock string, d) Maddox rod, e) closed-eye turns, f) Near Point of Convergence, and g) PERRLA with consensual reflex. The data from the neurological assessments is used to determine that an absence of suspicion of neurological injury is indicated in the subject.

In some embodiments, a display system comprising a head-mountable, augmented reality display is configured to perform a neurological analysis and to provide a perception aid based on an environmental trigger associated with the neurological condition. Performing the neurological analysis may include determining a reaction to a stimulus by receiving data from the one or more inwardly-directed sensors; and identifying a neurological condition associated with the reaction. In some embodiments, the perception aid may include a reminder, an alert, or virtual content that changes a property, e.g. a color, of a real object. The augmented reality display may be configured to display virtual content by outputting light with variable wavefront divergence, and to provide an accommodation-vergence mismatch of less than 0.5 diopters, including less than 0.25 diopters.
