摘要： In one example of the invention a patient display is provided on which a fixation graphic or video is shown in substantially the center of the display, and then target graphics or video are shown at different positions on the display about the center. A test subject is positioned in front of the patient display a known distance therefrom, and a camera captures an image of the test subject's eyes, to allow gaze direction determination to be performed. The captured images are displayed to a clinician user by a controlling test application, the clinician making a determination based on the images as to whether the test subject saw a target graphic or video when it was displayed. The clinician user then makes an appropriate input into the controlling test application, which also logs the position at which the target image was displayed. By displaying target graphics at multiple locations on the screen and logging the clinician inputs, the controlling test application is able to build up a plot of the peripheral vision field of the test subject. This plot can then be graphically displayed to the clinician user, and stored with the test results for future clinical use.
摘要翻译： 在本发明的一个示例中，提供了患者显示器，其中在显示器的大致中心处显示了固定图形或视频，然后在显示器上的不同位置处显示关于中心的目标图形或视频。 测试对象被定位在患者显示器的前方与其相距已知距离，并且照相机拍摄测试对象的眼睛的图像，以允许执行注视方向确定。 捕获的图像通过控制测试应用程序显示给临床医生用户，临床医生基于图像确定测试对象是否在显示时看到目标图形或视频。 临床医生用户然后对控制测试应用程序进行适当的输入，该控制测试应用程序还记录目标图像的显示位置。 通过在屏幕上的多个位置显示目标图形并记录临床医生的输入，控制测试应用程序能够建立测试对象的周边视野图。 然后该图可以以图形方式显示给临床医生用户，并与测试结果一起存储以备将来临床使用。
