Eye movement auditory biofeedback was used in weekly training sessions to control nystagmus in five adult patients. Within the 1st hr of training, all patients were able to reduce nystagmus. Average maximum group reduction of nystagmus amplitude, peak slow-phase velocity, and frequency achieved during training with auditory biofeedback was 82, 86, and 34%, respectively. At periodic intervals during training, audio information was withheld and patients were able to maintain reduced nystagmus for several minutes. In addition, patients were able to reduce nystagmus upon command without audio cues but with conscious effort while engaging in conversation and other tasks with the experimenters. Visual acuity improvement with conscious patient effort to control nystagmus but without auditory biofeedback averaged 10% Snell-Sterling. One of two patients who returned for post-training reevaluation was able to reduce his nystagmus quickly without auditory biofeedback to 50% of the pretraining level, and both patients were able with the aid of auditory cues to reduce their nystagmus rapidly to the level achieved during training. In addition to the improvement in vision, cosmetic and psychological benefits accrued. Eye movement auditory biofeedback should be considered in the treatment of nystagmus, either alone or in conjunction with orthoptic and/or surgical procedures.
眼动听觉生物反馈被用于每周一次的训练课程中，以控制5名成年患者的眼球震颤。在训练的第1小时内，所有患者都能够减少眼球震颤。在听觉生物反馈训练期间，眼球震颤幅度、慢相峰值速度和频率的平均最大组内减少率分别为82%、86%和34%。在训练期间的定期间隔，音频信息被 withheld，患者能够在几分钟内保持减少的眼球震颤。此外，患者能够在没有音频提示但有意识努力的情况下，在与实验者交谈和进行其他任务时根据指令减少眼球震颤。患者有意识地努力控制眼球震颤但没有听觉生物反馈时，视力平均提高了10%（斯内尔-斯特林）。两名返回进行训练后重新评估的患者中的一名能够在没有听觉生物反馈的情况下迅速将其眼球震颤减少到训练前水平的50%，并且两名患者在听觉提示的帮助下能够迅速将其眼球震颤减少到训练期间达到的水平。除了视力改善外，还获得了美容和心理益处。眼球震颤的治疗应考虑采用眼动听觉生物反馈，可单独使用或与视轴矫正法和/或外科手术联合使用。
