Diagnostic performance of ocular ultrasonography compared to fundoscopy to predict papilledema

Abstract

pressure, this pressure may transfer to the optic nerve sheath leading to swelling of the nerve head and thus active nerve inactivation. Despite its rare occurrence, it may appear at any age with no sex and racial predilection. 3 clinically, manifestations of papilledema are mostly secondary to increased intracranial pressure including headache, nausea and vomiting, pulsatile tinnitus, impaired vision, diplopia, and visual acuity impairment in very advanced P apilledema is mainly characterized by optic disc swelling secondary to elevated intracranial pressure due to a wide spectrum of cerebral pathological conditions such as intracranial tumor lesions, venous sinus thrombosis, inflammation, and ventricular obstruction or encephalitis. 1 the pathophysiological basis of this phenomenon is based on axoplasmic flow stasis accompanied with intra-axonal edema. 2 following an increase in intracranial
