title: [Therapy for cerebral visual perception disturbances].
abstract: Cerebral visual disorders are frequent after brain damage (20-40%). Among them, homonymous field defects and associated reading and visual exploration disorders, reduced visual acuity, contrast sensitivity and light/dark adaptation, fusional disorders, visuospatial deficits, multimodal hemineglect, and Balint-Holmes syndrome are the most common. Prototypical symptoms are the omission of obstacles and hemianopic alexia in visual field disorders, blurred vision in reduced acuity and/or contrast sensitivity or impaired fusion, blinding in impaired light adaptation and dark vision in impaired dark adaptation, and impaired action and orientation in visuospatial deficits. Neglect is characterized by omissions of stimuli on the contralesional side in space or the body. Patients with Balint-Holmes syndrome show severe spatial and attentional deficits. Systematic treatments can be categorized as restitution, compensation, and substitution approaches. Hemineglect can be ameliorated by novel, more effective treatment approaches, whereas only initial stages of treatment are available for Balint-Holmes syndrome.
