Abstract
The present disclosure relates to a device for visual field testing 11, which maps eye function of a test subject, the device comprising a display unit 17 displaying stimuli 23 to the test subject, and an eye tracking unit 19 detecting eye motions in response to the displayed stimuli. The display unit 17 displays at least a first 23 and a second 25 peripheral stimulus at different sectors in relation to a point of fixation 27 at the same time and the eye tracking unit determines which of the first and second stimulus is first gazed upon by the test subject. This allows different parts of the retina to compete with regards to retinal sensitivity and allows for a precise and efficient visual field testing.
Claims21
A device for visual field testing, mapping eye function of a test subject, the device comprising a display unit for displaying stimuli to the test subject, an eye tracking unit for detecting eye motions in response to the displayed stimuli, and an analyzing unit for determining a visual field characteristics based on the displayed stimuli and a corresponding eye tracking response, characterized by the display unit being configured to display at least a first and a second peripheral stimulus at different sectors in relation to a point of fixation, and in a common time frame, and the eye tracking unit or the analyzing unit being configured to determine which of the first and second stimulus is first gazed upon by the test subject.
A non-transitory computer-readable medium for mapping eye function of a test subject over a visual field, the medium comprising instructions stored thereon that when executed on a processor cause the processor to:
- displaying stimuli to the test subject using a display unit, detecting eye motions in response to the displayed stimuli by means of an eye tracking unit, and analyzing a visual field characteristics based on the displayed stimuli and a corresponding eye tracking response, characterized by the instructions causing the display unit to display at least a first and a second peripheral stimuli at different sectors in relation to a point of fixation, and in a common time frame, and to determine, using eye tracking unit, which of the first and second stimulus is first gazed upon by the test subject.
