We investigated the incidence of spontaneous nystagmus in 30 normal volunteers using electronystagmography (ENG). In all subjects, ENG was performed with the eyes open in the primary position, with the eyes closed, and with the eyes open in total darkness. Spontaneous nystagmus was detected in 5 (16.7%) of 30 subjects. In 15 subjects who underwent 2 ENG examinations, 4 subjects (26.7%) exhibited spontaneous nystagmus. Caloric testing was performed in 26 of 30 subjects. Spontaneous nystagmus was detected in 3 subjects who had a right-left difference in caloric response of over 40%, and in 2 of 23 subjects who had a difference of less than 40%. Our results showed that spontaneous nystagmus was detected in more subjects when the ENG examinations were repeated. Thus, a single ENG examination cannot exclude the possibility of spontaneous nystagmus.
我们使用眼震电图（ENG）对30名正常志愿者的自发性眼球震颤发生率进行了调查。对所有受试者，均在睁眼于初始位置、闭眼以及在完全黑暗环境中睁眼的情况下进行ENG检查。30名受试者中有5名（16.7%）检测到自发性眼球震颤。在接受两次ENG检查的15名受试者中，4名（26.7%）出现自发性眼球震颤。30名受试者中的26名进行了冷热试验。在冷热反应左右差异超过40%的3名受试者以及差异小于40%的23名受试者中的2名检测到自发性眼球震颤。我们的结果表明，重复进行ENG检查时，检测到自发性眼球震颤的受试者更多。因此，单次ENG检查不能排除自发性眼球震颤的可能性。
