[Visual contribution to the postural system: a clinical approach to the study of vision].

The clinician posturologist studies vision as one of the sources of informations about the small movements of the body relative to its environment, informations which enable controlling postural stability. But this way of working, very restrictive indeed, acquires a great clinical dimension because visual information must be integrated with all the other postural informations, and it appears that this integration is not always satisfactory and that its disorders can be detected and cured in many illnesses.
