Abstract

Apparatus for testing a subject's visual field includes a data processor, which can be provided by a general purpose computer, coupled to a pupil tracking system. The data processor is programmed to cause targets to be displayed at different locations on a display screen and to determine from the pupil tracking system whether the subject's pupil has moved in response to display of each target. In some embodiments, the pupil tracking system comprises an infrared camera.

Description

[0001] References to related applications [0002] This application claims priority to US Patent Application No. 60 / 893,800, filed March 8, 2007. For applications in the United States, this application is based on 35 U.S.C. §119, benefiting from U.S. Patent Application No. 60 / 893,800, filed March 8, 2007, which is hereby incorporated by reference in its entirety In this application. technical field [0003] The present invention relates to apparatus and methods for visual field testing. Background technique [0004] "Visual filed" refers to the spatial arrangement of visual perceptions observable by an object. "Field of view" refers to physical objects and light sources in the external world mapped onto the subject's retina. In other words, the field of view is everything that causes light to fall on the retina (in a given amount of time). The field of view is processed through a vision system which calculates the field of view as output. In optometry and ophthalmology...
