title: [New technics of examining the central visual field].
abstract: The examination of the central visual field with the help of automatic or semi-automatic field analyser leads to a great number of false negative or false positive results. Therefore, we tried to develop two modified perimetric techniques: they allow a continuous variation of light intensity and a quantitative recording of relative scotomas. For the investigation we can use a well-known card-grid. By a new arrangement of the gitter lines, it is possible to analyse nerve fiber scotomas. The results of these new perimetric techniques distinguish themselves by the fact that they can be swiftly executed and are helpful for detecting small central and paracentral scotomas.
