■ The purpose of rehabilitation is to optimize the use of residual vision by compensating strategies aimed at regaining and maintaining the patient's independence and quality of life. ■ Visual field defects involving the visual field center cause reading problems. ■ Fluent reading requires sufficient resolution and a sufficiently large retinal area used for reading, i.e., the reading visual field. ■ It is important to know whether fixation is central or eccentric. ■ Diminished resolution, as in central scotoma, can be compensated for by using a healthy visual field area at the edge of the scotoma (eccentric fixation) as well as text magnification. ■ In cases with a reduced size of the reading visual field and central fixation, it is crucial for the patient to learn to use an eccentric fixation locus despite intact foveal function. In ring scotomas only then reading is regained by magnification. In hemianopia, eccentric fixation of 1º-2º creates a small perceptual area along the vertical midline, while magnification is contraindicated. Here saccadic search strategies are also helpful. In concentric fields, contrast enhancement of small print sometimes helps to get enough letters into the central seeing island. ■ Peripheral visual field defects cause difficulties with spatial orientation, which can be improved by visual and tactile aids as well as mobility training. ■ Any attempt to rehabilitate a patient is worthwhile, because the success rate of technical aids in combination with training is high. ■ Training needs to be specifically tailored to the patient's deficits and needs, and it should be relevant to everyday life.
