Figure 2 (A) Microperimetry of the right eye before Audio-Luminous Biofeedback Training (BT). The red cross indicates the preferred retinal locus (PRL) and the red arrow indicates the trained retinal locus (TRL), located 2° below the PRL. (B) Microperimetry of the left eye. The red arrow indicates the retinal point corresponding to the TRL selected in the right eye. This point represents the area of best residual visual sensitivity in the left eye.
