Apparatus and method for objective perimetry visual field test

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. 本发明涉及用于测试对象视野的设备，包括可以由通用计算机提供的数据处理器，并与瞳孔跟踪系统相连接。数据处理器受程序控制而在显示屏的不同位置产生要显示的目标，并从瞳孔跟踪系统判断对象的瞳孔是否响应目标的显示位置而进行了移动。在一些实施例中，瞳孔跟踪系统包括红外照相机。
