Abstract

Secondary saccades bring the fovea on the target missed by primary saccades. The authors studied secondary saccades in the responses recorded from 76 healthy subjects during a normal refixation paradigm, focusing their attention on their latency (L2). L2 proved to be negatively related to target amplitude and positively to precision and latency of the corresponding primary saccade; the authors were not able to find any linear relationship with subject's age. On the basis of these relationships, they determined a three-class L2 distribution: decreased, normal and increased L2. A subject can be reliably evaluated comparing (chi-square test) his own frequency of L2 values belonging to each class with the frequencies observed in the controls; if a difference exists, the Kimball test enables the identification of the class from which this difference possibly arises.
