WebThe current study aimed to identify whether ultrasonographic measurements of optic nerve sheath diameter (ONSD) could dynamically and sensitively evaluate real-time intracranial … WebResults: 44 studies were included, with a total of 2984 patients. All causes of increased ICP were included, but the most common etiology was traumatic brain injury (TBI). The most used reference standard was CT scan. In the 27 non-pediatric studies that determined an optimal ONSD cutoff, the weighted mean of optimal cutoff was 5.26mm.
