WebJun 29, 2024 · Two components of ocular POCUS can be used to help evaluate for increased intracranial pressure. The first tool is measurement of the diameter of the optic nerve sheath, assessed at 3 mm deep to the optic disc. When measuring this, it is important that the optic nerve is parallel to the ultrasound beam. WebMar 1, 2024 · Our conclusion suggests that ocular ultrasonography is a reliable diagnostic technique to be utilized in all the cases of suspected raised intracranial pressure. To obtain the best possible accuracy and precision in the least invasive way, standardized A-scan seems to be the best choice.
