Optic Nerve Sheath Diameter on Sonography in Idiopathic Intracranial Hypertension Versus Normal.
OBJECTIVE To compare the mean optic nerve sheath diameter (ONSD) in patients with idiopathic intracranial hypertension (IIH) versus normal healthy individuals using B-scan ultrasonography as diagnostic tool. STUDY DESIGN Cross-sectional analytical study. PLACE AND DURATION OF STUDY Armed Forces Institute of Radiology and Imaging, Rawalpindi, Pakistan, from June to December 2015. METHODOLO...
متن کاملVolumetric assessment of optic nerve sheath and hypophysis in idiopathic intracranial hypertension.
BACKGROUND AND PURPOSE Idiopathic intracranial hypertension is a headache syndrome characterized by increased CSF pressure. Compression of the hypophysis and distension of the optic nerve sheath are reliable imaging signs. The purpose of the study was to validate, in patients with idiopathic intracranial hypertension, MR imaging-based volumetric measurements of the optic nerve sheath and hypoph...

Presentamos el caso de un varón de 14 años diagnosticado de hidrocefalia obstructiva y lesión ocupante de espacio en mesencéfalo, en contexto del estudio de cefalea de un mes de evolución. Trasladado a nuestra UCIP por cefalea, sono-fotofobia, adormecimiento de miembros superiores y detección de papiledema en su hospital de origen. Al ingreso está estable hemodinámica y respiratoriamente. Se re...
متن کاملOptic nerve diameters and perimetric thresholds in idiopathic intracranial hypertension.
AIMS/BACKGROUND Idiopathic intracranial hypertension (IIH) is a central nervous disorder characterised by abnormally increased cerebrospinal fluid (CSF) pressure leading to optic nerve compression. An indirect estimate of increased CSF pressure can be obtained by the ultrasonographic determination of optic nerve sheaths diameters. Computerised static perimetry is regarded as the method of choic...
متن کاملUltrasound measurement of optic nerve diameter and optic nerve sheath diameter in healthy Chinese adults
BACKGROUND Measurement of optic nerve sheath diameter (ONSD) is a fast and non-invasive method in detecting elevated intracranial pressure. However, the reported normal range of ONSD was inconsistent. The objective of the study was to determine the normal range of ONSD in healthy Chinese adults. METHODS Eyeball transverse diameter (ETD), optic nerve diameter (OND), and ONSD were measured by u...
