Neurotologic signs and symptoms, especially vestibular symptoms are common in migrainous patients. Involvement of the visual system in migrainures has received a great deal of attention in recent years, but the oculomotor part of the visual system has been largely ignored. The goal of this study was to investigate some parts of the central vestibular system using the oculomotor part of videonystagmographic evaluation, including spontaneous nystagmus, gaze-evoked nystagmus, smooth pursuit, saccade and optokinetic ystagmus interictally in migrainous patients.
In this case-control study, 30 patients with migraine and 38 healthy volunteers within the age range of 18-48 years old were included spontaneous nystagmus; gaze-evoked nystagmus in right, left and up sides, smooth pursuit, optokinetic nystagmus using three different velocities and saccade test performed in both groups. The data were analyzed using SPSS for Windows 18.0.
Some parameters of gain and phase and also morphology of the smooth pursuit, velocity of the saccade and slow phase velocity of optokinetic were significantly different in migrainures, although the statistical differences of these parameters were not clinically important as they were in the normal range of a defined device.
These results may suggest the presence of subtle otoneurologic abnormalities in migrainous patients that is probably due to the efficiency of oculomotor function with vestibulocerebellar origin.
神经耳科症状和体征，尤其是前庭症状在偏头痛患者中很常见。近年来，偏头痛患者视觉系统的受累受到了广泛关注，但视觉系统的动眼神经部分在很大程度上被忽视了。本研究的目的是利用视频眼震图评估的动眼神经部分，包括发作间期的自发性眼震、凝视诱发眼震、平稳跟踪、扫视和视动性眼震，来研究中枢前庭系统的某些部分。
在这项病例对照研究中，纳入了30例年龄在18至48岁之间的偏头痛患者和38名健康志愿者，对两组均进行了自发性眼震；右侧、左侧和上方的凝视诱发眼震、平稳跟踪、三种不同速度下的视动性眼震以及扫视试验。使用SPSS for Windows 18.0对数据进行分析。
偏头痛患者的平稳跟踪增益和相位的一些参数以及形态、扫视速度和视动性眼震慢相速度存在显著差异，尽管这些参数的统计学差异在临床上并不重要，因为它们处于特定设备的正常范围内。
这些结果可能提示偏头痛患者存在细微的耳神经学异常，这可能是由于起源于前庭小脑的动眼神经功能效率所致。
