AIMS/BACKGROUND: To examine the effects of acupuncture at the sternocleidomastoid muscles on foveation characteristics in congenital nystagmus.
Six patients with congenital nystagmus (CN) received a series of treatments consisting of two needles inserted into each sternocleidomastoid, stimulated by tapping gently every 5 minutes, for 20 minutes per session. Their eye movements were recorded using scleral search coils and changes in their CN waveforms analysed at each point in the treatment. Changes in the stability and duration of foveation periods were examined.
Four of the six patients showed improved foveation at the commencement of treatment; three maintained this response throughout the treatment period and after the needles were removed. In two, the CN waveform itself was modified.
This study and others involving afferent stimulation to the neck and face suggest that projections from these areas to the reticular formation and vestibular nucleus may alter the behaviour of the pathophysiological mechanism underlying congenital nystagmus.
目的/背景：研究针刺胸锁乳突肌对先天性眼球震颤注视特征的影响。
6例先天性眼球震颤（CN）患者接受了一系列治疗，即在每侧胸锁乳突肌插入两根针，每5分钟轻轻敲击进行刺激，每次治疗20分钟。使用巩膜搜索线圈记录他们的眼球运动，并在治疗的每个时间点分析CN波形的变化。检查注视期稳定性和持续时间的变化。
6例患者中有4例在治疗开始时注视改善；3例在整个治疗期间及拔针后维持这种反应。2例患者的CN波形本身发生了改变。
本研究及其他涉及对颈部和面部传入刺激的研究表明，这些区域向网状结构和前庭核的投射可能改变先天性眼球震颤潜在病理生理机制的行为。
