We examined 35 patients with unilateral cerebral lesions to determine the incidence of lateral deviation of the eyes under forcefully closed lids and the reliability of this sign in predicting the side of the lesion. Only patients with radiologically confirmed unilateral lesions were studied. Over 70% of patients had contralateral ocular deviation (Cogan's "spasticity of conjugate gaze"), 20% had ipsilateral deviation, and less than 9% of the patients had no deviation. Lateral ocular deviation was as sensitive, but not as specific, as a unilateral Babinski plantar response in determining the side with the lesion. Contralateral deviation was more common with parietotemporal localization, suggesting that the phenomenon reflects an underlying disturbance of attentional mechanisms.
我们检查了35例单侧脑损伤患者，以确定用力闭眼时眼球侧向偏斜的发生率以及该体征在预测损伤侧别方面的可靠性。仅研究了经影像学证实为单侧损伤的患者。超过70%的患者出现对侧眼偏斜（科根氏“共轭凝视痉挛”），20%出现同侧偏斜，不到9%的患者无偏斜。在确定损伤侧时，眼球侧向偏斜与单侧巴宾斯基跖反射一样敏感，但特异性不如后者。对侧偏斜在顶颞叶定位时更为常见，提示该现象反映了潜在的注意力机制紊乱。
