SMOOTH-PURSUIT AND SACCADIC EYE-MOVEMENTS AND WISCONSIN CARD SORTING TEST-PERFORMANCE IN OBSESSIVE-COMPULSIVE DISORDER

Smooth pursuit eye movements (SPEMs), voluntary saccadic eye movements (VSEMs), and neuropsychological test (Touluse-Pieron Test and Wisconsin Card Sorting Test) performance were studied in 23 patients with obsessive-compulsive disorder and 27 age-matched normal control subjects. The patients performed more poorly than the control subjects on the SPEM and, to a lesser degree, VSEM measures. They also showed impairment on some aspects of the neuropsychological tests. No relationship was found between eye movement performance and neuropsychological impairment.
