Improved optical coherence tomography systems and methods to measure retinal data are presented. The systems may be compact, provide in-home monitoring, and have automation to allow the patient to measure himself or herself.

An apparatus for vision testing comprises a visual test unit (VTU) configured to receive a patients face and perform the vision test on the patient. The VTU includes an internal display configured to generate a light stimulus and a gaze sensor configured to track the eye of the patient. In one aspect, a plurality of VTUs form a system controllable by a common technician to concurrently administer vision tests on different patients. In another aspect, the gaze sensor comprises a camera configured to capture a video of the patients eye displayed to the technician. In another aspect, the VTU is configured to pause testing upon detection of an adverse testing condition such as excessive head tilt or a closed eye. In another aspect, the test display comprises an array of LEDs and a perforated opaque screen to provide sufficient luminance. In another aspect, the VTU comprises a head mounted portion with a pair of focusing lenses and a mirror arranged to transmit light from the test display to the eyepiece and from the eyepiece to the gaze sensor. In another aspect, the VTU includes a patient input device configured to receive input from the patient to signal observance of a light stimulus in the visual field around a fixation point, and the VTU is configured to monitor the patients gaze and pause the test upon detecting that the patients gaze has moved from the fixation point.

An ophthalmic apparatus includes an objective lens, and an OCT optical system optical system is configured to project a measurement light onto a subject's left or right eye via an objective lens, and to detect interference light between returning light of the measurement light a reference light having traveled through a reference optical path. An optical axis switching member switches an optical axis of the OCT optical system to approximately coincide with a first or second measurement optical axis. A controller is configured to control the optical axis switching member. An intraocular parameter calculator calculates an intraocular parameter of the subject's left or right eye based on a detection result of the interference light acquired in a state where the optical axis of the OCT optical system is switched so that the optical axis of the OCT optical system approximately coincides with the first or second measurement optical axis.

Systems and methods are disclosed for evaluating human eye tracking. One method includes receiving data representing the location of and/or information tracked by an individual's eye or eyes before, during, or after the individual performs a task; identifying a temporal phase or a biomechanical phase of the task performed by the individual; identifying a visual cue in the identified temporal phase or biomechanical phase; and scoring the tracking of the individual's eye or eyes by comparing the data to the visual cue.

Systems and methods according to present principles use touchscreen-based devices such as tablet computers or other computers incorporating touchscreens to both run the test and to receive input/output. It will be understood that any such device may be employed, so long as a display, means for user input, and means for eye tracking, are provided, and so long as its display screen is large enough to effectively test visual field.

A visual function inspecting system, configured to: determine, when a subject animal is arranged to face visual information moving in a predetermined direction, a moving speed of a visual line direction of the subject animal changing over time, based on information indicating the visual line direction obtained for a predetermined period of time; determine a frequency characteristic of the moving speed of the visual line direction based on the determined moving speed of the visual line direction changing over time; and inspect a visual function of the subject animal based on the determined frequency characteristic.

A panum's area measurement method includes: projecting a first parallax image of a spatial object to the left eye of a user under test, and projecting a second parallax image of the spatial object to the right eye of the user under test, the first parallax image comprising a first homologous point and the second parallax image comprising a second homologous point; adjusting a horizontal parallax amount between the first homologous point and the second homologous point until the user under test observes the spatial object producing a ghost; acquiring a parallax amount parameter Δn.sub.e; calculating a horizontal physical spacing Δx between the first homologous point and the second homologous point based on the parallax amount parameter Δn.sub.e; and calculating a panum's area range (μ.sub.in, μ.sub.out) of the user under test based on the horizontal physical spacing Δx.

An optical system includes a lens unit configured to form a first intermediate image by using light from a light source, a first optical element configured to transmit the light from the first intermediate image and to move to rotationally scan a target, and a second optical element configured to guide the light from the first optical element to the target.

In accordance with one aspect of the present invention, an optical coherence tomography-based ophthalmic testing center system includes an optical coherence tomography instrument comprising an eyepiece for receiving at least one eye of a user or subject; a light source that outputs light that is directed through the eyepiece into the user's or subject's eye, an interferometer configured to produce optical interference using light reflected from the user's/subject's eye, an optical detector disposed so as to detect said optical interference; and a processing unit coupled to the detector. The ophthalmic testing center system can be configured to perform a multitude of self-administered functional and/or structural ophthalmic tests and output the test data.

An ophthalmologic apparatus includes a visual target projection system that is configured to present a visual target to a subject eye at a predetermined examination distance under a presentation condition according to the examination distance, and a controller that is configured to control the visual target projection system. The controller is configured to control the visual target projection system to present the visual target at a first examination distance for a far-point examination of the subject eye, a second examination distance for a near-point examination of the subject eye, and at least one third examination distance different from the first examination distance and the second examination distance.
