Maculopathy can have many causes: congenital, hereditary and acquired. The response of a maculopathy is the formation of a scotoma that can be relative or absolute with difficulty or impossibility to read, write and see the normal activities of daily life. The visually impaired person therefore has an insufficient level of visual ability to perform daily activities, work or leisure activities that are usual for individuals of the same age, sex and sociocultural status. A more or less serious low vision and a visual disability are thus created. The visually impaired person is able to use the eccentric visual residue in the preferential retinal network. With visual rehabilitation, a visual capacity lost by the patient is gained, developing eccentric fixation, giving the patient the awareness of his own possibilities to see and use the use of optical and electronic aids.
