Résumé
In macular diseases,there is a typical development of a central scotoma which is responsible for the central visual acuity loss,reading speed reduction and changing in fixation stability.The prevention and treatment of degenerative macular disease have not yet received satisfying functional results.Effectiveness of biofeedback treatment in visual rehabilitation has been evidenced in several studies.The microperimeter can improve their visual abilities and lay the basis for new,more manageable visual aids by using cerebral plasticity and neurosensorial adaptation to the central scotoma of patients with macular diseases.The purpose of this review is to summarize key fmdings on characteristics of central scotoma,the plasticity of human visual system and visual rehabilitation via microperimetry.
