“Ultrasonographic Measurement of Optic Nerve Sheath Diameter: A Noninvasive Method for Estimating Intracranial Pressure in Traumatic Brain Injury Patients”

https://pubmed.ncbi.nlm.nih.gov/38114797

This scoping review suggests that ultrasonographic measurement of optic nerve sheath diameter has strong accuracy and correlation with invasive methods, making it one of the most effective noninvasiveive techniques for estimating intracranial pressure in traumatic brain injury patients.
