The quantitative evaluation of small central and paracentral scotomas is a problem. Examination of the central visual field with an automatic or semiautomatic field analyzer can lead to a great number of false-positive results. Therefore, we have tried to develop two modifications of perimetric techniques: they allow continuous variation of the light intensity and quantitative recording of relative scotomas. For the investigation we used the well-known caro grid. With a new arrangement of the grid lines, it is possible to analyze nerve fibre scotomas. The results of the new perimetric techniques are presented.
对小的中心性和旁中心性暗点进行定量评估是个难题。使用自动或半自动视野分析仪检查中心视野会导致大量假阳性结果。因此，我们尝试开发两种视野检查技术的改进方法：它们能使光强度连续变化并对相对暗点进行定量记录。为进行研究，我们使用了著名的卡罗方格。通过网格线的新排列，可以分析神经纤维暗点。本文展示了新视野检查技术的结果。
