Optic 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 کاملUltrasonographic evaluation of optic disc swelling: comparison with CSLO in idiopathic intracranial hypertension.
PURPOSE To determine the accuracy and reproducibility of ultrasonographic (US) readings of optic disc elevations in patients with papilledema compared with confocal scanning laser ophthalmoscope (CSLO) measurements. METHODS One randomly selected eye of 22 patients with idiopathic intracranial hypertension (IIH) and a variable degree of optic disc swelling underwent five and three repeated mea...
متن کاملOptic Nerve Compression by an Intracanalicular Meningioma.
THE diagnosis of progressive unilateral visual failure, when occurring as a solitary symptom in association with a visual field defect and when all routine investigations are negative, presents many difficulties. Amongst the conditions to be considered are retinal vascular disease, chronic simple glaucoma, atypical forms of toxic amblyopia, optic neuritis, and optic nerve compression. Meadows (...
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...
متن کاملOptic Nerve Head Quantification in Idiopathic Intracranial Hypertension by Spectral Domain OCT
OBJECTIVE To evaluate 3D spectral domain optical coherence tomography (SDOCT) volume scans as a tool for quantification of optic nerve head (ONH) volume as a potential marker for treatment effectiveness and disease progression in idiopathic intracranial hypertension (IIH). DESIGN AND PATIENTS Cross-sectional pilot trial comparing 19 IIH patients and controls matched for gender, age and body m...
