Efforts to evaluate findings in the nystagmogram were made in a material of 338 vertiginous and dizzy patients. A spontaneous nystagmus, a positional nystagmus as well as a difference in caloric reactivity are as solitary findings of lettle value for revealing peripheral disorders. On the other hand, central disturbances are frequently revealed by inability to track a moving optic target, resulting in an irregular or a saccadic pattern, by persistence of vestibular nystagmus in light, by persistence of such nystagmus at eye-closure, by an increase in spontaneous nystgmus on eye-closure or by dysrhythmic nystagmus in caloric tests. Cases of functional vertigo seem to differ from cases of vertigo from other sources by their increase of spontaneous nystagmus (when present) or by persistence of caloric nystagmus on eye-closure.
对338例眩晕和头晕患者的材料进行了眼震图检查结果的评估。自发性眼震、位置性眼震以及冷热反应差异作为孤立发现，对于揭示周围性疾病的价值不大。另一方面，中枢性障碍常表现为无法跟踪移动的视觉目标，导致眼动模式不规则或呈扫视样，在亮光下前庭眼震持续存在，闭眼时该眼震持续存在，闭眼时自发性眼震增加，或冷热试验中出现节律异常的眼震。功能性眩晕病例似乎与其他原因引起的眩晕病例不同，表现为自发性眼震增加（如果存在）或闭眼时冷热眼震持续存在。
