Abstract
Quantitative studies of vertical saccades are sparse, due to a lack of reliable recording techniques. In this study, electro-oculographic (EOG) and photo-electronystagmographic (PENG) techniques showed that up-directed saccades were faster than down-directed ones. In the EOG recording, however, the velocity of the up-directed saccade was correlated to the size of an artifact caused by movement of the upper eye lid. Further investigations are needed to analyse the characteristics of vertical eye movements.
摘要
由于缺乏可靠的记录技术，关于垂直扫视的定量研究很少。在本研究中，眼电图（EOG）和光电眼震图（PENG）技术表明，向上的扫视比向下的扫视更快。然而，在EOG记录中，向上扫视的速度与上眼睑运动引起的伪迹大小相关。需要进一步研究来分析垂直眼动的特征。
