Eye movements in visual search indicate impaired saliency processing in Parkinson's disease. Abstract Text:

Previous studies have produced contradictory evidence on the nature of the visual search impairment in patients with Parkinson's disease (PD). Eye movements were measured during multi-target search in nine individuals with mild-to-moderate PD. Subjects were asked to click on a response button whenever they judged they were fixating a target for the first time. Compared to age-matched healthy volunteers, PD patients were impaired at efficient search (detecting "+"s amongst "L"s) but not inefficient search ("T"s amongst "L"s). However, these patients had normal memory for locations as indexed by their rate of re-clicking on previously inspected locations. We suggest that the pattern of gaze for efficient search may reflect impaired saliency processing in PD.
