Figure 6: Relative amplitude of ERG components (mean ± SEM) during and after IOP elevation to 50 mmHg for 42 min.     (circles),     (squares), and nSTR (triangles) amplitudes are compared. Horizontal reference lines indicate baseline and zero levels. Open boxes show the duration of IOP elevation. Reprinted from [57] with permission.
