Core Tip
Core Tip: Non-traumatic headache can be the first sign of raised intracranial pressure, requiring rapid recognition to prevent neurological deterioration. Conventional diagnostics such as computed tomography and lumbar puncture have limitations. Point-of-care ultrasound measurement of optic nerve sheath diameter is a fast, non-invasive method with high sensitivity and specificity for detecting elevated intracranial pressure. Its use can expedite diagnosis, guide urgent management, and reduce unnecessary imaging, especially in outpatient and resource-limited settings. Standardized training and emerging artificial intelligence-assisted measurement promise to enhance its reliability and broaden its clinical impact.
