Dissociative and conversive disorders are disorders which originate from the former concept of hysteria. Dissociative disorders are disorders which are characterized by a disruption of and/or discontinuity in the normal, subjective integration in one or more facets of psychological processes. Some of these facets can be memory, identity, consciousness emotion, perception. Conversion disorder is defined as the emergence and course of one or more symptoms that are caused by psychological conflicts or needs affecting the voluntary motor or perceptual functions, without the presence of an organic impairment. Classification of dissociative and conversive disorders, same as their relationship, remain a very controversial domain, and so some authors and classifications advocate their seperation, while others cosider conversive disorder a type of a dissociative disorder. The cause of these disagreements is the long and turbulent hystory of hysteria and the lack of the scientific consensus around the etiology of dissociative and conversive disorders. It has been shown in scientific research that the emergence of the syptoms is usually connected with some kind of trauma or pschyological conflict, but there are etiological models that deny this connection. Dissociative disorders include: dissociative identityy disorder, depersonalisation/derealization disorder, dissociative amnesia and trance disorder. Psychotherapeutic methods and farmacotherapy are in most cases used for their treatment. One of the domains in which dissociative disorder can have negative influence is also the visual functioning. Before the term in literature used to be hysterical blindness or hysterical amblyopia to describe the visual impairment in persons with visual impairment without the organic cause which were diagnosed with hysteria. Today the terms used include: functional vision loss, non-physiological vision loss, non-organic vison loss, psychogenic vision loss, medically unexplained vision loss and conversive visual disorder. Symptoms include: blindness, tunell vison, diplopia, photophobia, visual distorsions and visual hallucinations. In this paper the scientific literature will be presented connected to visual impairment of people which are diagnosed with hysteria, dissociative or conversive disorder. Visal impairment in these disorders causes severe problems in everyday functioning, but despite that there is a significant lack of research which explores this topic and visual impairment lives in the shadow of other symptoms of dissociative disorders.
