The ocular bobbing phenomenon consists of involuntary, abrupt, usually conjugate, brisk downward eye movements followed by a slow return to midposition; it is most often observed in cases of coma due to pontine vascular lesions. In the patient reported here, with a coma after basilar thrombosis, the movement was initially conjugate and subsequently limited to one eye, as described by SUSAC and coworkers under the heading "monocular bobbing" in 1970. The movement was increased in amplitude and frequency by labirintine caloric stimulation as well as by non specific manoeuvres like neck skin pinching and visual stimulation. Post-mortem examination showed a large ischaemic infarction of the pons, of the middle cerebellar peduncles and of the white matter of one cerebellar hemisphere.
眼球跳动现象表现为不自主、突然、通常为共轭性的快速向下眼球运动，随后缓慢回到中间位置；最常见于脑桥血管病变导致的昏迷病例。在本文报道的患者中，因基底动脉血栓形成后昏迷，该运动最初是共轭性的，随后如1970年苏萨克及其同事在“单眼跳动”标题下所描述的那样，局限于一只眼睛。通过迷路性温热刺激以及诸如掐捏颈部皮肤和视觉刺激等非特异性操作，该运动的幅度和频率增加。尸检显示脑桥、小脑中间脚和一个小脑半球白质有大面积缺血性梗死。
