Comparison of Photopic Negative Response of Full-Field and Focal Electroretinograms in Detecting Glaucomatous Eyes

Figure 3

The PhNR amplitudes of the full-field (a) and focal ERGs (b) center, (c) superior/temporal, and (d) inferior/temporal) are plotted for the normal controls (564131.fig.008) and glaucomatous eyes at early (■), intermediate (), and advanced stages (). Bars represent means of the PhNR amplitudes.
