Figure 4 (A) Microperimetry of the left eye before BT. (B) Microperimetry of the left eye after BT of the other eye. Comparison of the tests demonstrates a diffuse overall increase in retinal sensitivity compared to before training. The average sensitivity improved from 2.0 dB to 2.6 dB. This improvement is particularly evident in the increased number of sensitivity points.
