Conversion disorder is defined by Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV) as symptoms affecting voluntary motor or sensory function, resembling a neurological condition, and, after investigation, cannot be explained by this condition, but by psychological factors. On rare occasions, neurological examination and laboratory tests are not sufficient to establish the diagnosis of conversion disorder. This article describes a case for which the use of a technique of suggestion (torpedoing) confirmed the diagnosis of conversion blindness and also proved to be effective for its treatment. Suggestion, combined with psychotherapy and psychopharmacology, can be a valuable tool in the treatment of these patients.
