We used electrooculography to study the saccadic velocities, smooth pursuit, and vestibular ocular reflex in a patient with an acute thalamic hemorrhage. Our findings confirmed what others have shown in that there were hypometric saccades contralateral to the lesion, impaired smooth pursuit ipsilaterally, and a preserved vestibular ocular reflex. In addition, we demonstrated an asymmetry with the contralateral eye being more affected. It is also shown that the "convergence" movements seen on attempted upgaze are typical of saccades and not vergence movements. A discussion of possible pathophysiologic mechanisms with review of other studies is presented.
我们使用眼电图来研究一名急性丘脑出血患者的扫视速度、平稳跟踪和前庭眼反射。我们的研究结果证实了其他人的发现，即病变对侧存在低幅扫视，同侧平稳跟踪受损，前庭眼反射保留。此外，我们还证明了对侧眼受影响更大的不对称性。研究还表明，试图向上注视时出现的“集合”运动是典型的扫视运动，而非辐辏运动。本文还对可能的病理生理机制进行了讨论，并回顾了其他研究。
