The dependence of the human c-wave from the step amplitude was studied qualitatively. The maximum of the c-wave is achieved with light stimuli longer than 10 sec. After a dark period of 10 sec a fully developed c-wave appears. Also, in response to a brilliant photoflash a c-wave could be recorded. The influence of a mobile pupil on the response in the(More)
Three out of 18 healthy persons investigated with the DC-ERG do not show a c-wave. By varying the adaptation levels and intensities of the stimuli four components in the human ERG can be isolated, the cone and rod late receptor potentials, the positive DC response, and a c-wave in most subjects. It is suggested that investigation of these components reveals(More)
More than 60 patients with retinal vessel occlusions were examined using the electro-oculogram (EOG) ramp test. In the course of the disease a systematic disturbance of the slow oscillation of the corneoretinal potential occurred. First, the latency of the light peak increased. Then the peak decreased and was reached up to 5 min later than in the healthy(More)
The EOG test is divided into two parts: a light and a dark test. The adaptation period is extended to 30 min. During this adaptation period the luminance in the cabin decreases (or increases) slowly to the starting value of the light or dark step. In a model, we studied the influence of this ramplike luminance course on the results. Standard values for the(More)
The “fast oscillation” of the corneoretinal potential can be precisely examined by means of cyclic light stimuli and an automatic measuring device. This new procedure is carried out during the period of adaptation as part of the usual EOG-test. Normal values and some clinical findings are presented. The fast oscillation may provide additional information(More)
BACKGROUND High sensitive troponin assay methods used in emergency departments and those used in hospital laboratories are needed with low imprecision of the analytical method aligned along the cut-off. METHODS Presented is a method for adjusting the Troponin I (TnI) assay on the AQT90 FLEX analyzer (Radiometer) to the UniCel DxI 800 immunoassay system(More)
