视网膜静脉搏动的发生机制及其临床应用价值

Mechanism and clinical application of spontaneous retinal venous pulsations

自发性视网膜静脉搏动（SVPs）可以在90％的正常人群中观察到，表现为视盘上的一条或多条视网膜静脉节律性的轻微收缩或扩张。国外多项研究表明，SVPs可用于颅内压监测及青光眼的诊断和随访，而目前国内尚未对这一现象进行研究和应用。尽管有关SVPs的发生机制存在争议，但其潜在的临床应用价值日益受到关注。就SVPs发生机制的研究现状及其测定方法和临床研究等方面的最新进展进行综述。

Spontaneous retinal venous pulsations（SVPs）appears in 90% of normal persons. It is seen as a rhythmic subtle narrow and expansion of one or more retinal veins on the optic disc. Many researches have demonstrated that SVPs could be applied to the intraeranial pressure（ICP） monitoring as well as diagnoses and fellow up of glaucoma. But there is no corresponding domestic research in this field up to now. Although the physiological mechanism of the venous pulsations has been the point of much debate, its potential clinical value attract our attention. The present paper reviewed the progress in current understanding of the mechanism behind the SVPs, the examination method and application of SVPs in clinical study.
