PURPOSE To determine the effects of stimulus eccentricity and luminance level on the reaction time (RT) of young normal volunteers during automated kinetic campimetry. METHODS We used a specially designed video-campimetric device equipped with a continuous infrared (IR) pupillographic fixation control (Tübingen Computer Campimeter) and recorded reaction(More)
The difference in threshold sensitivities that are found when examining the visual field (VF) with static versus kinetic perimetric methods is called stato-kinetic dissociation (SKD). In this pilot study, we describe a semi-automated procedure for quantifying SKD. Fifteen patients with VF defects were examined with kinetic and static perimetry. SKD values(More)
To evaluate pathogenetic mechanisms and frequency distribution of visual field defects (VFDs) in patients with chiasmal lesions. Secondly, to reconsider the existence of “Wilbrand’s knee” as far as referable to the anterior junction syndrome. Consecutive visual field records related to chiasmal lesions were retrieved from the Tuebingen Perimetric Database.(More)
BACKGROUND Presentations based on slides, videos and/or computer presentations are usually sequentially structured, resulting in an inflexible order of the demonstrated information and examination results. However, in (medical) education such a system only inadequately reflects the real physician-patient situation. MATERIALS AND METHODS The software(More)
BACKGROUND Conventional kinetic perimetry is of especial use in case of advanced scotoma. However, examiner dependency is a major drawback. Purpose of this study was to evaluate the clinical feasibility and intraindividual scatter of computer-assisted kinetic perimetry in monitoring advanced visual field defects of various origins. METHODS Examinations(More)
Fundus-oriented perimetry (FOP) was used to evaluate the effectiveness of different-sized bright and dark stimuli in detecting and quantitatively measuring angioscotoma. The foveolas and optic disks of digitized fundus images were aligned with their psychophysical counterparts to construct individual grids of perimetric stimuli. Each grid included a linear(More)
Selected neuro-ophthalmological cases demonstrate the diagnostic capabilities of adequate perimetric techniques: centripetally condensed stimulus arrangement and threshold-oriented, slightly supraliminal perimetry revealed even very small homonymous visual field defects, resulting from a small cortical lesion not exceeding the extent of the calcarine(More)
