“…Sensitivity and specificity have ranged from 83–100% and 84–100% using direct measurement of cerebrospinal fluid pressure or CT as a gold standard reference,15,16,33,34,36,37,39 but have been reported to be as low as 75% and 44%, respectively 35. In a recent meta-analysis of 12 studies including 478 adults and children, sensitivity and specificity for detecting CT findings associated with increased ICP were 95.6% and 92.3%, respectively 40.…”

“…Noninvasive devices do not reliably quantify ICP [46]. However, they may be used to estimate ICP when invasive monitoring is not feasible, along with information from imaging [47][48][49]. It remains a mandatory prerequisite, exploring the volume relationship inside the skull, when other intracranial monitors, exploring other domains, are used to provide a framework for optimal interpretation (Fig.…”

“…The normal limits in one study might not be normal in another study. [5,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] Amini et al determined that the threshold value of ONSD at higher sensitivity and specificity levels was 5.5 mm in patients with an elevated lumbar puncture opening pressure of >20 cm H2O. [20] In addition, Caffery et al reported that the threshold value of 5.0 mm did not have adequate sensitivity and specificity, despite using the same methodology.…”

“…[20] In addition, Caffery et al reported that the threshold value of 5.0 mm did not have adequate sensitivity and specificity, despite using the same methodology. [26] Regarding the ultrasonographic image quality in particular, artifacts and user experience are the most significant factors for presenting different threshold values. [11] Increased ICP can be observed during the natural period of intracranial injury.…”
