目的：为了实现人工操作繁琐、眼球运动频繁的眼底周界检查的自动化，我们利用计算机技术开发了一种新的眼底周长自动测量系统。这两个单元都是在Windows(TM)上运行的个人计算机。在眼底预置测量点后，将自动执行视野测量。眼底追踪单元识别和追踪眼底参考区域，同时在视野检查期间实时计算其坐标。目标显示单元利用眼底追踪单元的数据校正刺激坐标，即使发生眼球运动，也会自动将刺激目标显示在预先设定的正确视网膜点处。结果：该自动测量系统可以自动、准确地进行眼底视野检查。结论：该自动化测量系统将使眼底视野检查更方便，更便于临床使用。(C)2002年日本眼科学会。
Purpose: In order to automate fundus perimetry, which is usually laborious because of the many manual operations and the frequent eye movements, we developed a new fundus perimeter with an automated measuring system using computer technology.Methods: This fundus perimeter consists of an infrared fundus camera, a fundus-pursuit unit, and a target-display unit. Both units are personal computers operating on Windows(TM). After presetting the measuring points on the fundus, perimetry is automatically performed. The fundus-pursuit unit recognizes and pursues the fundus reference region while calculating its coordinates in real time during perimetry. The target-display unit corrects the stimulus coordinates with data from the fundus-pursuit unit and even if eye movement occurs, automatically displays the stimulus targets at the correct retinal point that had been preset.Results: Fundus perimetry can be automatically and precisely performed with this automated measuring system. It shortens the duration of the examination and frees the operator from the lengthy and laborious manual operations during perimetry.Conclusions: This automated measuring system will make fundus perimetry easier for the operator, as well as more popular for clinical use.
