Full-field electroretinogram (ffERG). Image A: 3.0 ffERG under dark-adapted conditions (rod-cone response). Image B: 0.01 ffERG (rod response). Image C: 30 Hz flicker (light adaptation, cone response). Image D: 3.0 ffERG oscillatory potencials (amacrine cells). A decreased amplitude is obtained in OU under photopic (A and C) and scotopic (B and D) conditions, more severe in OD
