The visually controlled eye tracking systems (saccadic, smooth pursuit, and optokinetic) were compared in 25 young and middle-aged normal subjects (mean age, 42 years), 14 elderly patients with vertebrobasilar insufficiency (VBI) (mean age, 67 years) and 14 elderly normal subjects (mean age, 65 years). The young normal subjects were consistently superior to both elderly groups on all measurements, but there was no significant difference between the performance of patients with VBI and the elderly normal subjects. This study emphasizes the critical importance of taking age into consideration when evaluating saccades, smooth pursuit and optokinetic nystagmus.
对25名年轻及中年正常受试者（平均年龄42岁）、14名患有椎基底动脉供血不足（VBI）的老年患者（平均年龄67岁）和14名老年正常受试者（平均年龄65岁）的视觉控制眼动追踪系统（扫视、平稳跟踪和视动性）进行了比较。年轻正常受试者在所有测量指标上均始终优于两个老年组，但VBI患者与老年正常受试者的表现之间无显著差异。这项研究强调了在评估扫视、平稳跟踪和视动性眼球震颤时考虑年龄的至关重要性。
