6. Evaluation of Elevated Intracranial Pressure

Evaluation of Elevated Intracranial Pressure/Papilledema

Elevated intracranial pressure (ICP) may be a sign of a serious or life-threatening medical condition and it may be helpful to augment the fundoscopic exam with ultrasound to evaluate for papilledema which can be from a chronic increase in intracranial pressure.

Intracranial Pressure Evaluation with Ocular Ultrasound

Ultrasound of the optic nerve sheath diameter has proven to be a reliable, non-invasive, and rapid method to estimate ICP measurement. Any elevation in ICP causes distension of the ocular nerve sheath (>5mm) likely within minutes, making it a prime way to measure ICP in emergent situations
