Saccadic and pursuit eye movements were measured in a patient with a right thalamic hemorrhage using an infrared reflection technique. Saccades were hypometric when directed away from the side of the lesion, and pursuit was low in gain, with many interposed saccades, when directed toward the side of the lesion. This eye movement pattern is similar to that observed in hemidecorticate patients. We postulate that the ocular abnormalities observed in our patients were secondary to an interruption of the efferent pathways from the right cerebral areas mediating saccadic and smooth-pursuit eye movements.
采用红外反射技术对一名右侧丘脑出血患者的扫视和跟踪眼球运动进行了测量。当扫视方向远离病变侧时，扫视幅度减小；当跟踪方向朝向病变侧时，跟踪增益降低，且有许多插入性扫视。这种眼球运动模式与在半侧皮质损伤患者中观察到的模式相似。我们推测，在我们的患者中观察到的眼部异常是由于介导扫视和平滑跟踪眼球运动的右侧脑区传出通路中断所致。
