Abstract
A case is reported of a young man with a clinical diagnosis of schizophrenia and unusual oculo-motor abnormalities. The relationship between oculo-motor dysfunction and hemispheric balance in schizophrenia is discussed.
Highlights
Disordered eye movement in schizophrenia has been recognized since the turn of this century (Diefendorf and Dodge, 1908)
Eye movements said to be under hemispheric influence include: smooth pursuit eye movements, saccadic eye movements and conjugate lateral eye movements (Lipton et at., 1980)
Pursuit movements hold a moving image, steady on the fovea, an example being the slow phase of vestibular nystagmus
Summary
Disordered eye movement in schizophrenia has been recognized since the turn of this century (Diefendorf and Dodge, 1908). Several abnormalities have been described involving saccades, smooth pursuit and conjugate lateral eye movements (Holzman et al, 1976; Iacono, 1988). We describe a patient with magnetic attraction of gaze, an abnormality previously reported in patients with focal right hemisphere insults (De Renzi, 1988). In view of the increasing evidence that schizophrenia may have an underlying cerebral dysfunction in the form of hemisphere imbalance (Cutting, 1990) the occurrence of the same phenomenon in schizophrenia is of some interest
