Advances in the clinical application of ultrasonic measurement in optic nerve sheath diameter / 中国综合临床

ABSTRACT

Due to the special anatomic structure of optic nerve,the optic nerve sheath diameter( ONSD) increases along with the elevated intracranial pressure(ICP). The normal value or cut?off point of ONSD has not been unified in adults and children. The change of ONSD in children is different from that of adults as the children are at the stage of growth. With the deep understanding of ONSD,ultrasonic measurement of ONSD has a wide range of applications in adults and children.
