    摘要： The invention relates to a computer program that when executed on a computer causes a system to execute a method, particularly a computer-implemented method for determining a plurality of functional ocular parameters, with the system comprising an optical system (3) with a display system (4) that is configured to independently project a visual stimulus to a left and a right eye of a test person, an eye-tracking system (5) configured to record a gaze direction (100) and a pupil size (102) of the left as well as the right eye, said computer (2) being configured to control the optical system (3) and to receive recorded data from the eye-tracking system (5), wherein an afferent pupillary defect (APD), particularly a relative afferent pupillary defect (RAPD) is determined from a first trial session consisting of a sequence of first kind of stimuli presented to the left and the right eye of the test person eyes with the display system (4), and wherein a visual field (400) is determined from a second trial session consisting of a sequence of second kind of stimuli presented to the left and the right eye of the test person with the display system (4), wherein from the first and/or the second trial session a strabismus is determined as well, by determining one or more strabismus angles.

    摘要： The present disclosure generally relates to methods and apparatus for accurate identification of the visual axis of the eye. In one embodiment, a visual axis identification system includes a fixation light source, a camera, a processing system, and a multifocal lens. The patient focuses their gaze through the multifocal lens and onto a fixation light beam provided by the fixation light source. The passage of the fixation light beam through the multifocal lens creates two or more images on or near to the patient's retina. The multifocal lens and/or the patient's eye are then moved relative to each other while the patient continuously maintains their gaze on the fixation light beam. The patient's visual axis may be located by determining the location of the optical center of the multifocal trial lens relative to the patient's eye when the centers of the multiple images coincide on the retina.

    摘要： A perimeter, including two types: one is a fixation forcing perimeter, and the other is an objective perimeter combined with electro-physiology under forced fixation; the perimeter comprises a fixation forcing device, a display conduction device, a perimetry display device, a feedback device for recording feedback information, and a control center for controlling the perimetry display device and collecting feedback information; the fixation forcing device comprises a negative pressure ring (2) and a negative pressure tube (3), and is adsorbed to the eyeball by negative pressure; when the eyeball moves, the fixation forcing device moves synchronously, and the fixation is forced at the same position, thereby eliminating the influence of a fixation point on the examination results of the perimeter; in the objective perimeter, an electro-physiological signal after forced fixation is automatically recorded by an electro-physiological instrument, so that the subjective response of a patient is eliminated, and the examination results are objective; and the change in the field of view can be early discovered using the electro-physiological signal as an analysis indicator.

    摘要： A visual sense examination device includes: a beam source that emits a visible beam and an invisible beam; a visible beam optical system that includes a first scanner scanning the visible beam; an invisible beam optical system that includes a second scanner scanning the invisible beam; a detector that detects the invisible beam reflected by a retina of a subject; a controller that performs a first control; a synthesizer that synthesizes the visible beam scanned by the first scanner and the invisible beam scanned by the second scanner; and wherein scanning angles of the visible beam by the first scanner and the invisible beam by the second scanner are substantially the same, and projectable ranges of the visible beam scanned by the first scanner and the invisible light scanned by the second scanner are substantially the same on the retina of the subject.
