Position does not affect the optic nerve sheath diameter during laparoscopy
BACKGROUND Increase in intracranial pressure (ICP) is one of the physiologic changes during laparoscopic surgery, which is known to be associated with positional changes. Changes of ICP can be measured directly by invasive method, but ultrasonographic measurement of optic nerve sheath diameter (ONSD) is known to be a rapidly applicable technique for evaluating ICP. The aim of this study is to i...
متن کاملExertion Does Not Affect the Optic Nerve Sheath Diameter in Healthy Participants
The purpose of this study was to determine if exertion influences the ONSD in healthy individuals. Healthy adults were eligible for inclusion. Activities were performed by each participant for 60 seconds and were as follows: sprinting, holding a 10-pound weight with both arms outstretched parallel to the floor, a Valsalva maneuver, a plank position, and positioning the head down thirty degrees ...
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...
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 کاملOptic nerve sheath diameter in normal-tension glaucoma patients.
BACKGROUND To report on the optic nerve sheath diameter (ONSD) in patients with normal-tension glaucoma (NTG) compared with controls without known optic nerve (ON) or intracranial disease. METHODS In 18 patients with NTG (mean age 64.9 ± 8.9 years; 7 women and 11 men), CT of the orbit was performed. 17 age- and gender-matched patients without ON or intracranial disease, who underwent CT of th...
