title: The distribution of normal values in automated perimetry.
abstract: From 354 visual fields of 137 normal subjects, various components of variance were calculated separately for each test location of the Octopus automated-perimetry program J0. The method of component analysis of variance was used. The following components were analyzed: interindividual variation (variation of visual-field measurements in different subjects), long-term fluctuation (variation of different visual-field measurements in the same subject), differences between the right and left eyes and fluctuation within one visual field test in one subject, i.e., short-term fluctuation. The results show increased variations at the center relative to the paracentral area and a slight increase with eccentricity.
