Measurement of optic nerve sheath diameter (ONSD) using point of care ultrasound has been used to indirectly assess the intracranial pressure (ICP) particularly in conditions where it is raised. Direct pressure measurements using probes reaching the ventricle system correlated with ONSD using ultrasound. Attempts were made to measure the ONSD pre and post lumbar puncture (LP) after draining cerebrospinal fluid (CSF) as well as post ventricular shunt placement. We report ONSD measurement and demonstrate dynamic changes during LP in a patient with known idiopathic intracranial hypertension (IIH).
使用即时超声测量视神经鞘直径（ONSD）已被用于间接评估颅内压（ICP），特别是在颅内压升高的情况下。使用到达脑室系统的探头进行直接压力测量与超声测量的 ONSD 相关。有人试图在腰椎穿刺（LP）后引流脑脊液（CSF）前和后以及脑室分流器放置后测量 ONSD。我们报告了一名已知特发性颅内高压（IIH）患者的 ONSD 测量值，并展示了 LP 过程中的动态变化。
