UNLABELLED
Electronystagmography (ENG) and videonystagmography (VNG) are eye movement recording methods used for the evaluation of balance disorders.
AIM
To compare literature information on the similarities, differences, advantages e disadvantages between ENG and VNG.
MATERIALS AND METHODS
review of the scientific literature.
RESULTS
ENG and VNG are very helpful methods for evaluating balance disorders, due to their capacity to recognize signs of peripheral or central vestibular dysfunction and to pinpoint the side of the lesion. Major advantages of VNG are related to calibration, temporospatial resolution, and recording of horizontal, vertical and torsional eye movements.
CONCLUSION
VNG is a new technology that presents advantages in the evaluation of eye movements; however, despite its disadvantages, ENG is still considered a valuable test in the clinical setting.
目的
比较眼震电图（ENG）和视频眼震图（VNG）在相似性、差异、优势和劣势方面的文献信息。
材料和方法
对科学文献进行回顾。
结果
ENG 和 VNG 是评估平衡障碍非常有帮助的方法，因为它们能够识别周围或中枢前庭功能障碍的迹象，并确定病变的侧别。VNG 的主要优势与校准、时空分辨率以及水平、垂直和扭转眼球运动的记录有关。
结论
VNG 是一种新技术，在眼球运动评估方面具有优势；然而，尽管存在缺点，ENG 在临床环境中仍被认为是一种有价值的检查方法。
