Treatment algorithm. Section of the visual field of a patient including an area of intact (dotted) and anopic (light shading) vision. The "treatment area" (dark shading) is a rectangular area in which LEDs are stimulated in a systematic way (here from left to right). White spots: normal reaction times. Grey spots: prolonged reaction times within the reaction interval. Black spots: delayed or no reactions (errors). See text for details.
