ABSTRACT
Objective To investigate the eye-movement features of smooth pursuit in subjects at clinical high risk for psychosis.Methods sixty subjects at clinical high risk for psychosis and sixty healthy controls were recruited.The smooth pursuit tasks were assessed in both horizontal (0.4 Hz) and Lissajous (0.2 or 0.4 Hz) condition.The Wechsler Memory Scale-third edition and spatial span subtest were used to assess working memory.The difference of the smooth pursuit performance between the two groups and the relationship between smooth pursuit and working memory were analyzed.Results Subjects at clinical high risk for psychosis showed significantly lower Horizontal components for pursuit gain [Lissajous 0.2 Hz task (0.82±0.12) vs.(0.89±0.09),Lissajous 0.4 Hz task (0.78±0.13) vs.(0.84±0.14)],lower vertical components for pursuit gain [Lissajous 0.2 Hz task (0.80±0.14) vs.(0.86±0.12),Lissajous 0.4 Hz task (0.71±0.15)vs.(0.77±0.16)] and higher mean positional error [Lissajous 0.2 Hz task (37.00±19.10) vs.(30.45± 16.18),Lissajous 0.4 Hz task (44.18±19.70) vs.(37.61±16.26)] compared to healthy controls (P<0.05).There was a significant correlation between pursuit gain and performance on Spatial Span (Horizontal componentsr=0.361,P=0.005;vertical componentsr=0.327,P=0.01 1) in the Subjects at clinical high risk for psychosis.Conclusions Subjects at clinical high risk for psychosis showed deficits in smooth pursuit,and the deficits were related to the working memory.
