Transorbital Ultrasonography Used to Detect Papilledema, in a Patient With Intracranial Hypertension

Abstract

Intracranial hypertension (IH) is an important cause of secondary brain injury, and it is often associated with poor outcomes; due to that monitoring of intracranial pressure (ICP) is essential for the management of neurocritical patients. Although invasive methods have been the gold standard for ICP monitoring, recent non-invasive ultrasonography techniques have been used to estimate ICP. Among the most used methods are the measurement of the diameter of the optic nerve sheath and transorbital ultrasonography to evaluate papilledema. This presented case is of a patient with refractory IH due to subarachnoid hemorrhage, measured through an intraventricular catheter. A transorbital sonogram was performed and showed the presence of papilledema.
