Assessment of spontaneous venous pulsation (SVP) is commonly undertaken to help determine whether intracranial pressure (ICP) is elevated. Previous studies using direct ophthalmoscopy or slit-lamp assessments have found that SVP is not observed in 67%–81% of subjects with normal ICP, and that interobserver agreement when grading SVP is poor.

用红外摄像检测自发静脉搏动。


通常进行自发静脉搏动（SVP）评估来帮助确定颅内压（ICP）是否升高。先前使用直接检眼镜或裂隙灯评估的研究发现，67%–81% ICP 正常的受试者没有观察到 SVP，并且当 SVP 分级时观察者间的一致性较差。
