Ultrasound 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...
متن کاملUltrasonographic optic nerve sheath diameter measurement in overweight parturient with intracranial tumour: Guiding choice of anaesthesia
A 26‐year‐old 36‐week primigravida with body mass index of 28.33 with intracranial space occupying lesion was planned for elective caesarean section. The patient was having frontal headache for past 1 month with left eye ptosis for last 3 weeks. Headache was associated with vomiting. There was no history of seizures. Magnetic resonance imaging (MRI) obtained 3 weeks before showed large lobulate...
متن کاملAssessment of intracranial pressure with ultrasonographic retrobulbar optic nerve sheath diameter measurement
BACKGROUND Ultrasonograpic retrobulbar optic nerve sheath diameter (ONSD) measurement is considered to be an alternative noninvasive method to estimate intracranial pressure,but the further validation is urgently needed. The aim of the current study was to investigate the association of the ultrasonographic ONSD and intracranial pressure (ICP) in patients. METHODS One hundred and ten patients...
متن کاملCoronal Axis Measurement of the Optic Nerve Sheath Diameter.
OBJECTIVES The true optic nerve sheath diameter cutoff value for detecting elevated intracranial pressure is variable. The variability may stem from the technique used to acquire sonographic measurements of the optic nerve sheath diameter as well as sonographic artifacts inherent to the technique. The purpose of this study was to compare the traditional visual axis technique to an infraorbital ...
متن کاملTransorbital Sonographic Evaluation of Normal Optic Nerve Sheath Diameter in Healthy Volunteers in Bangladesh
INTRODUCTION Measurement of optic nerve sheath diameter (ONSD) by ultrasound is increasingly used as a marker to detect raised intracranial pressure (ICP). ONSD varies with age and there is no clear consensus between studies for an upper limit of normal. Knowledge of normal ONSD in a healthy population is essential to interpret this measurement. METHODS In a prospective observational study, O...
