抄録

Active head turn with eyes closed may involuntarily induce transient saccadic eye deviation (TSD) in the direction of the head movement. This suspected of being provoked by activation of the lateral gaze center due to neck torsion.<BR>Using a computer, the maximal eye velocities of TSDs and visually elicited voluntary saccades of 20 degree were analyzed in 89 subjects aged 9 to 84. The mean velocity of TSD in subjects over 70 years of age was slower than that in the other age groups excluding the small number of subjects under age 20. In particular, a significant difference was noted between the elderly subjects and those in their 50s. Voluntary saccades, however, did not differ between age groups.<BR>In conclusion, age-related change in eye velocity was seen in involuntary TSD, but not in voluntary saccades. The velocity of TSD may be available for an assessment of aging.
