Abnormalities of eye movement are associated with work hours in schizophrenia

Abstract

Eye movement abnormalities have been reported in schizophrenia; however, their influences on everyday life remain unknown. From data on 69 subjects with schizophrenia and 246 healthy subjects, we found positive correlations between eye movement measures and work hours, which were only significant in subjects with schizophrenia. This relationship was also confirmed in a multi-site dataset including 118 subjects with schizophrenia and 280 healthy subjects. These findings further strengthen our understanding of eye movement abnormalities and their relevance in clinical recovery.
