title: Normal values of the basic level of the standing potential and its light rise.
abstract: The amplitude and the light rise of the standing potential of the eye were measured in a group of 20 male and 10 female health young subjects. The basic value itself, if measured in the steady state, has a variability not far from its light rise, so it can also be applied clinically. The median base value in our group was 362 microV, with normal limits of 233 and 680 microV. If the light rise is calculated in relation to its basic level, the variability of such a ratio is lower than the variability of the light peak/dark trough ratio. The mean value of our ratio wa 2.19 with a lower limit of 1.57. Maximal normal difference between two eyes of the same subject was 122 microV for the basic value, and 0.45 for the ratio.
