本文介绍了一种受人类视觉系统启发而设计的眼睛监视器。监视器包含眼睛对于摄像机看起来像什么的内部表示或模型。该系统可以在存在干扰噪声的情况下以及在佩戴眼镜或隐形眼镜的患者中测量眼睛的位置和瞳孔的大小，并且它可以容忍由于患者在深度上的小移动而引起的散焦。该系统在测量瞳孔对受控光刺激的反应时，对头部和眼睛的运动进行实时校正。介绍了系统的设计和软硬件组成，并给出了一些应用实例.作为一个例子，它用于视觉疾病的早期临床检测，通过客观地测量瞳孔反应仔细控制光刺激检查。一些关于使用计算机在医学测量的一般意见。<<ETX>>
An eye monitor whose design is inspired by the human visual system is presented. The monitor incorporates an internal representation or model of what the eye looks like to a video camera. The system can measure the position of the eyes and the size of the pupil in the presence of interfering noise and in patients wearing eyeglasses or contact lenses, and it tolerates defocusing due to small movements in depth by the patient. The system makes real-time correction for head and eye movements while measuring pupillary responses to controlled light stimuli. The design and software and hardware components are described, and some applications are noted. Its use for early clinical detection of visual diseases by objectively measuring pupillary responses to carefully controlled light stimuli is examined as an example. Some general observations about using computers in medical measurements are made.<<ETX>>
