Contralateral deviation of the eyes was sustained for a week in a patient with discrete subcortical frontal lobe haematoma. When deviation recovered, ipsilateral saccades were hypo-metric and saccadic latencies were prolonged in both horizontal directions. Smooth pursuit was paretic during tracking toward the side of the haematoma. Pursuit gain was higher during tracking to the contralateral side. Smooth eye movement imbalance may explain the unusual finding of contralateral gaze deviation with frontal lobe damage.
一名患有局灶性皮质下额叶血肿的患者，双眼对侧偏斜持续了一周。当偏斜恢复时，同侧扫视幅度减小，且两个水平方向的扫视潜伏期均延长。向血肿侧追踪时，平稳跟踪出现麻痹。向对侧追踪时，追踪增益更高。眼球平稳运动失衡可能解释了额叶损伤时对侧凝视偏斜这一异常发现。
