Videonystagmoscopy visualizes nystagmus on a television monitor and records it on video tape for later study, records, and reproduction. Early attempts date from long ago, but the technique only recently has spread, since the development of complex computerized equipment which, however, confines it to certain vestibular exploration laboratories. In order for this technique to become more widely used, simple equipment is needed, such as that described in this article. Our system consists of a single infrared light minivideo camera that is attached to the left eye using an eyeglass-mounting system that also occludes the right eye. The examination method is routine. Our results show the following advantages over electronystagmography: visualization of the rotary component, non-interference of visual stimuli, mechanical and electronic stability, speed, and low cost. If necessary, it can be complemented by electronystagmography and computer analysis.
视频眼震电图检查可在电视监视器上观察眼震，并将其记录在录像带上以供日后研究、记录和再现。早期的尝试可追溯到很久以前，但这项技术直到最近才得以推广，这是由于复杂的计算机设备的发展，然而，这使得该技术仅限于某些前庭探索实验室使用。为了使这项技术得到更广泛的应用，需要简单的设备，如本文所述的设备。我们的系统由一个单红外光微型摄像机组成，该摄像机通过一个眼镜安装系统固定在左眼上，该系统同时遮挡右眼。检查方法是常规的。我们的结果显示，与眼震电图相比，具有以下优点：可观察到旋转成分、不受视觉刺激干扰、机械和电子稳定性好、速度快且成本低。如有必要，可辅以眼震电图和计算机分析。
