Abstract

The Auto-Plot perimeter is a projection perimeter designed for analysis of the central 30 degrees of the visual field. It supplies clean test spots, which can easily be varied in size and colour, and the results can be recorded rapidly. However, because the screen is flat, the size and illumination of the projected spots of light vary as the targets are moved outward from the fixation point. We have devised a very inexpensive curved screen which eliminates these disadvantages.

摘要

自动标绘视野计是一种用于分析中心30度视野的投射式视野计。它提供清晰的测试点，其大小和颜色易于改变，并且结果能够快速记录。然而，由于屏幕是平的，当目标从注视点向外移动时，投射光斑的大小和亮度会发生变化。我们设计了一种非常便宜的曲面屏幕，它消除了这些缺点。
