Sonographic evaluation of optic nerve diameter in children with raised intracranial pressure.
OBJECTIVE The optic nerve is part of the central nervous system, and a rise in intracranial pressure (ICP) can directly affect the perioptic nerve space, leading to an increase in nerve diameter. Transorbital sonography is a safe and easy-to-perform method to measure optic nerve diameter for rapid diagnosis of increased ICP. METHODS The optic nerve diameter was measured in 3 individual occasi...
متن کاملOptic nerve ultrasound for the detection of raised intracranial pressure.
BACKGROUND Optic nerve ultrasonography (ONUS) may help identify raised intracranial pressure (ICP). The optimal optic nerve sheath diameter (ONSD) cut-off for the identification of intracranial hypertension has not been established, with some clinical studies suggesting a higher cut-off than may be expected on the basis of prior laboratory investigation. OBJECTIVE To validate ONUS performed b...
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 کاملRaised intracranial pressure.
Raised intracranial pressure (ICP) is a common problem in neurosurgical and neurological practice. It can arise as a consequence of intracranial mass lesions, disorders of cerebrospinal fluid (CSF) circulation, and more diffuse intracranial pathological processes. Its development may be acute or chronic. There are well established methods for the measurement, continuous monitoring, and treatmen...
متن کاملsonographic optic nerve sheath diameter as a screening tool for detection of elevated intracranial pressure
introduction: timely diagnosis and treatment of post traumatic, elevated intracranial pressure (eicp), could reduce morbidity and mortality, as well as improve patients’ outcome. this study is trying to evaluate the diagnostic accuracy of sonographic optic nerve sheath diameter (onsd) in detection of eicp. methods: sonographic onsd of patients with head trauma or cerebrovascular accident suspic...
