摘要： A visual field testing apparatus comprises a display for displaying targets; a line of sight detection unit that detects a line of sight of a user and that outputs line of sight information pertaining to a direction of the line of sight; a visual recognition determination unit that carries out determination as to whether or not the user has visually recognized a target based on line of sight information and position information of the target; and a visual field testing unit that sequentially displays targets at prescribed locations at the display and that carries out testing of a range of visual field based on output from the visual recognition determination unit; wherein the visual field testing unit comprises a visual recognition detection feedback unit which, when it is detected due to output from the visual recognition determination unit that the user has visually recognized a target which is currently displayed at the display, carries out feedback processing for a prescribed time to let the user know that detection has occurred.

摘要： Provided is a contrast-sensitivity test device that is smaller than conventional ones and that enables a desired illumination environment to be easily set and enables a contrast sensitivity test to be conducted easily and accurately. The contrast-sensitivity test device includes: an illumination unit that emits illumination light such that a field of view of a subject is in a specified illumination environment; a visual target presentation unit that is located within the field of view of the subject and that switches and sequentially presents a plurality of visual targets having different contrasts; a response-time measurement unit that, when the illumination light is emitted, measures a response time after each visual target is presented until the subject recognizes the visual target; and a casing that houses the illumination unit, the visual target presentation unit, and the response-time measurement unit.

摘要： Embodiments of the invention are directed towards systems, methods and computer program products for providing improved eye tests. Such tests improve upon current eye tests, such as visual field tests, by incorporating a gamification of the testing process, software mediated guidance to the patient or practitioner such that more accurate results of the eye tests are obtained. Furthermore, through the use of one or more trained machine learning or predictive analytic systems, multiple signals obtained from sensors of a testing apparatus are evaluated to ensure that the eye test results are less error-prone and provide a more consistent evaluation of a user's vision status. As it will be appreciated, such error reduction and user guidance systems represent technological improvements in eye tests and utilize non-routine and non-conventional approaches to the improvement and reliability of eye tests.

摘要： An ophthalmologic apparatus includes a target projection system that presents an eye chart to a subject eye, an objective measurement optical system that objectively measures an eye characteristic of the subject eye, and a control portion that controls the target projection system and the objective measurement optical system, wherein the control portion presents the target for a predetermined time at a predetermined presentation position with the target projection system, and objectively measures the eye characteristic with the objective measurement optical system in a time series to control an operation of each portion based on a measurement result of the objective measurement.

摘要： A head-mounted display (HMD) determines whether a set of criteria is satisfied based on eye-related readings collected by a camera of the HMD and wirelessly transmits a set of messages in response to a determination that the set of criteria is satisfied. An attachment includes a set of light-emitting diodes (LEDs) and activates the set of LEDs to emit the light at the bleaching intensity in response to receiving the set of messages.

摘要： A medical ophthalmic system uses a patient-specific face mask to establish a predefined alignment between the ophthalmic system and an eye of a patient. The patient-specific face mask may optionally provide a light proof enclosure for the eye. The face mask may be coupled directly to an ophthalmic device, or its housing/enclosure, of the ophthalmic system. The face mask may be 3D printed based on a 3D model of the patient's face.

摘要： A system and method of detecting eye movements of a subject for the diagnosis of neurological disorders. The method includes tracking eye movements of the subject, identifying microsaccades from the tracked eye movements, and characterizing microsaccade dynamics of the identified microsaccades to determine one or more parameters, such as microsaccade direction, microsaccade velocity, microsaccade magnitude, microsaccadic peak velocity-magnitude relationship, microsaccade duration, and intersaccadic intervals. The method also includes comparing the one or more determined parameters with a corresponding control parameter, assessing the comparison to determine differences between the one or more determined parameters and the corresponding control parameters, and generating a report including the diagnosis of neurological disorder based on the assessment.

摘要： A system includes: at least one processor; a movable stage, wherein the movable stage is movable under control of the at least one processor with respect to an eye of a subject; a video display device configured to move with the movable stage; and an optical system disposed in an optical path between the video display device and the eye. The video display device is configured to play a movie of a fixation target to the eye to cause the eye to accommodate, and the movie dynamically changes an appearance of the fixation target on the video display device to compensate for Bokeh of the fixation target as the movable stage moves the video display device from a first position, where the fixation target draws a focus of the eye to near its far point, to a second position further away from the eye than the first position.
