Patients with congenital nystagmus exhibit a wide range of unusual nystagmus waveforms and strategies to obtain maximum visual acuity. We investigated target acquisition strategies, head-eye coordination, and the effects of alteration of head position relative to gravity on congenital nystagmus waveforms in five patients. No changes in the nystagmus were found when patients' heads were placed in different positions relative to gravity. Two patients had distinctive abnormalities of head-eye coordination characterized both by failure of eye movement to precede head movement and by position of the eye in the orbit, after target acquisition, being in a direction opposite that of the head movement. We conclude that static changes in head position relative to gravity probably do not influence congenital nystagmus waveforms. In addition, some patients with congenital nystagmus may have abnormal head-eye coordination.
先天性眼球震颤患者表现出广泛的异常眼球震颤波形以及获取最大视力的策略。我们研究了5例患者的目标获取策略、头眼协调以及相对于重力改变头部位置对先天性眼球震颤波形的影响。当患者头部相对于重力处于不同位置时，未发现眼球震颤有变化。两名患者存在独特的头眼协调异常，其特征在于眼球运动不能先于头部运动，且在获取目标后，眼球在眼眶中的位置与头部运动方向相反。我们得出结论，相对于重力的头部位置静态变化可能不会影响先天性眼球震颤波形。此外，一些先天性眼球震颤患者可能存在异常的头眼协调。
