Nystagmoid eye movements elicited by humming loudly was initially misdiagnosed as Tullio's phenomenon (abnormal acoustical stimulation of the vestibular apparatus owing to labyrinthine fistula). Further workup lead to a final diagnosis of a form of voluntary nystagmus characterized in some reports as "hysterical mystagmus". Some of the characteristics of this example of voluntary nystagmus differed from generally accepted descriptions.
大声哼唱引起的眼球震颤样眼动最初被误诊为图利奥现象（由于迷路瘘导致前庭器官受到异常声刺激）。进一步检查最终诊断为一种形式的随意性眼球震颤，在一些报告中其特征被描述为“癔症性眼球震颤”。这个随意性眼球震颤实例的一些特征与普遍接受的描述有所不同。
