Age-dependent changes in visually guided saccadic eye movements.
Voluntary horizontal saccadic eye movements (SEM) were recorded in 148 drug free healthy subjects (15-75 years of age). None had history and/or objective evidences of CNS abnormalities. SEM recordings took place always at the same time of the day, after a standard lunch. Peak saccadic velocity (PSV), saccade latency (SL) and saccade accuracy (SA) were extracted for each saccade session. A negative linear correlation was found between SEM parameters (PSV, SA, SL) and age. Aged subjects showed a significant (p less than 0.01) elongation of the to locate the target, a significant (p less than 0.01) decrease in PSV and a significant (p less than 0.01) decrement in SA.
