Abstract
• Disordered smooth-pursuit eye movements occur in a high percentage of schizophrenic patients and their first-degree relatives. A test of the hypothesis that these disorders represent a genetic indicator of schizophrenia was undertaken by testing pursuit eye movements in a sample of monozygotic and dizygotic twins discordant for clinical schizophrenia. Deviant eye tracking is significantly concordant within monozygotic twin pairs, and less so within dizygotic twin pairs discordant for schizophrenia. A genetic interpretation is consistent with these results.Keywords
