Pattern-onset electroretinograms (PERGs) with red-green color contrast (CC) and green-"black" luminance contrast (LC) stripe patterns (0.3 c/deg) were recorded in a group of 80 control subjects and in a group of 42 patients having glaucomas of varying etiology and severity. The PERG data were correlated with the results of static perimetry and optic disc morphometry. In the glaucoma group the PERG was reduced significantly and by relatively similar amounts with both CC and LC stimuli. A significant correlation of the PERG reduction with visual field loss was found only with the CC, not with the LC PERG. Correlations between PERG amplitudes and neuroretinal rim areas of the optic disk were similar for the LC and for the CC stimulus. The rather poor percentage of correct classification of controls and patients based on the PERG or the optic disc morphometry alone can be improved by two-dimensional discriminant analysis using both CC PERG and papillometry data.
