Optic 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...
متن کاملInfluence of retrobulbar neuritis and papillitis on echographically measured optic nerve diameter.
BACKGROUND/AIM Retrobulbar (optic) neuritis is inflammation of the optic nerve that may cause a complete or partial loss of vision. This inflammation can affect a part of the nerve within the eyeball (neuropapillitis) or a part of the nerve behind the eyeball (retrobulbar neuritis). The aim of this study was to establish whether there is a correlation between the diameter of a retrobulbar part ...
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 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 کاملThe Optic Nerve in Glaucoma
To recognize and to assess glaucomatous changes at the optic nerve, it is important to know the characteristics of the normal optic disc. As in the other biological variables, the appearance of the optic disc varies widely among healthy individuals. This fact is complicate the recognition of the pathological changes. ‘Optic Disc’ is frequently used to describe the portion of the optic nerve cli...
