The objective of this study was to determine the efficacy of intraocular pressure (IOP) measurements in diagnosing elevated increased intracranial pressure (ICP) by examining the correlation between optic nerve sheath diameter (ONSD) and IOP in the prone position.
This prospective observational study included patients in the American Society of Anesthesiologists (ASA) 1–2 risk group, aged 18–65 years, who were scheduled for elective surgery. ONSD and IOP measurements were performed with ultrasound and Tonopen XL.
Data from 59 patients were analysed. Spearman’s correlation analysis was used to determine the relationship between quantitative data. Significance was considered at < 0.05. ONSD and IOP measurements were significantly higher in the prone position ( = 0.001). However, no correlation was found between ONSD and IOP measurements.
We found that ONSD and IOP measurements increased in the prone position, but these two measurements were not correlated. ONSD can be used in the diagnosis and follow-up of elevated ICP. Since there are many factors affecting IOP values, we concluded that IOP would not be effective in the diagnosis and follow-up of ICP.
本研究的目的是通过检查俯卧位时视神经鞘直径（ONSD）与眼压（IOP）之间的相关性，确定眼压测量在诊断颅内压升高（ICP）中的有效性。
这项前瞻性观察性研究纳入了美国麻醉医师协会（ASA）1-2风险组、年龄在18-65岁、计划进行择期手术的患者。使用超声和Tonopen XL进行ONSD和眼压测量。
分析了59例患者的数据。采用Spearman相关分析来确定定量数据之间的关系。显著性水平设定为<0.05。俯卧位时ONSD和眼压测量值显著更高（P = 0.001）。然而，未发现ONSD与眼压测量值之间存在相关性。
我们发现俯卧位时ONSD和眼压测量值升高，但这两项测量不相关。ONSD可用于ICP升高的诊断和随访。由于影响眼压值的因素众多，我们得出结论，眼压在ICP的诊断和随访中无效。
