在本研究中，我们比较了在黑暗中睁眼旋转时的眼震反应和闭眼时的反应。闭眼减少了诱发的眼震反应，在30名受试者中，有20人的反应降低到了无法用眼震电图仪记录的程度。闭眼时眼球垂直偏斜与眼球震颤抑制程度有关。从目前的调查来看，在受试者闭上眼睛时进行的前庭外周功能检查往往会产生误导性的记录，这可能会导致不正确的结论。因此，记录前庭诱发眼球震颤的最好方法是在完全黑暗的情况下睁眼测试受试者。
In the present investigation the nystagmus response during rotation with open eyes in darkness was compared with the response recorded during eye-closure. Eye-closure reduced the induced nystagmus response and in 20 out of 30 subjects the response decreased to such an extent that it was impossible to record by electronystagmography. A relation was found between vertical eyeball deviation during eye-closure and the degree of nystagmus inhibition. From the present investigation it appears that examinations of the peripheral vestibular function carried out while the subjects' eyes are closed often give misleading recordings which may result in incorrect conclusions. The best way of recording vestibular induced nystagmus, therefore, is to test the subjects with eyes open in total darkness.
