Electroretinograms (P-ERG) and cortical potentials (P-VECP) evoked by checkerboard patterns were examined in patients with defects of the ganglion cell and nerve fiber layers due to glaucoma. Only a few patients exhibited a prolonged latency in the P-VECP, whereas in the P-ERG all patients with papillary and visual field defects revealed a significantly(More)
Electroretinographic responses to pattern-reversal stimuli (P-ERG) were recorded in eight patients with protracted elevation of intraocular pressure. Pressures of bigger than 30 mm Hg result in marked amplitude reductions in the P-ERG. The observed changes probably reflect the impaired function of retinal ganglion cells caused by decreased oxygen supply.
The authors report on clinical and electrophysiological studies of a patient with Type I Oguchi's disease. Numerous small pigmentations of the retinal pigment epithelium (RPE) causing focal disruption of the Oguchi reflex were observed, a phenomenon which has not previously been reported. Consistent with reports of pathologic changes in the RPE, an abnormal(More)
A connection has been established between the normal photopic electroretinogram (ERG) during amaurosis caused by retrobulbar anesthesia and former analogous investigations of visual evoked, cortical potentials (VECP). It proves the assumption that retrobulbar anesthesia causes a sensoric blockade of the optic nerve while the retina continues to function(More)
Resistance training has been shown to increase arterial stiffness. The purpose of the present study was to examine and compare the systemic arterial stiffness responses to acute lower body (LRT) and upper body (URT) resistance training. 20 healthy young men [median age: 26 years (interquartile range 23, 32)] underwent LRT, URT and whole body resistance(More)
Typical electroretinographic findings in x-chromosomal juvenile retinoschisis are a normal a-wave and a reduced b-wave suggesting that the primary defect is located at the level of the bipolar cell layer whereas deeper retinal structures are not basically affected. The marked amplitude reduction in the pattern-ERG suggests to look for the origin of response(More)

JEPonline 2007;10(1):48-56. The purpose of this investigation was to examine the effects of two resistance exercise intensities and testosterone replacement on changes(More)
All patients with autosomal dominant infantile optic atrophy had a normal electro-oculogram (EOG) and a normal luminance electroretinogram (L-ERG). Patients with a typical blue sensitivity defect at the time of investigation had a normal pattern electroretinogram (P-ERG), while the visually evoked cortical potentials to pattern stimuli (P-VECP) showed a(More)
