Correlation with age and sex of flash-evoked electroretinogram and retinal oscillatory potentials recorded with skin electrodes

“…The results outline age-related trends of variation that are consistent with previous findings [6,7,8,9,11,13,14], while the positive correlation with age of the ERG b-wave amplitude contrasts with the general agreement about a decrease of this variable with aging. Due to the wide range of age and the high significance at the linear regression test, this unexpected finding should not be accounted for by statistical accidents or depend on the data distribution or the subject sampling.…”

“…Dermal electrodes [3,4,5,6] should be a convenient alternative to conventional devices, while allowing comfortable recording also on healthy children and in the elderly. These subjects are in fact often excluded from normative electrophysiological studies when corneal electrodes are to be used [7,8,9,10,11], and biased control data might be referred to in human neuropharmacology despite the relevance within this context of age-related modifications.…”

The influence of age on the electroretinogram and visual evoked potential

“…Age-related changes in the electrical responses of the retina and cortex are an important consideration when analysing clinical data. Various workers have separately investigated the effect of age on the normal ERG to flash stimulation (Karpe et al, 1950;Zetterstrom, 1956;Zeidler, 1959;Straub, 1961 ;Peterson, 1968;Weleber, 1981 ;Martin and Heckenlively, 1982) and on the flash VEP (Kooi and Bagchi, 1964;Copenhaver and Perry, 1964;Dustman and Beck, 1966;1969, Buchsbaum et al, 1974Dustman et al, 1977;Cosi et al, 1982) and the pattern reversal VEP (Asselman et al, 1975;Celesia and Daly, 1977;Allison et al, 1979Allison et al, , 1983Stockard et al, 1979;Shaw and Cant, 1981;Snyder et al, 1981;Sokol et al, 1981;Halliday et al, 1982). There are few studies on age-related changes in VEPs evoked by pattern onset-offset stimulation, which is a subject of considerable interest (de Vries-Khoe and Spekreijse, 1982;Spekreijse et al, 1973;Jeffreys, 1977).…”
