title: [Continuous profile perimetry].
abstract: The present paper describes a modified form of profile perimetry. The brightness of a test mark moved at varying speed is increased, and as soon as it is supraliminal the examinee can press a button to reduce the brightness to subliminal again. The accuracy with which the threshold is determined is in the range of a few dB in 1-degree steps in the respective meridian. The reproducibility of the examination makes follow-up possible. A moderate loss of sensitivity can be recognized directly from the record, as can an increased short-term fluctuation of the light difference threshold. Results in subjects with healthy eyes and persons with ocular pathology are described. Possibilities for improvement, in particular to save more time, are discussed.
