Diffusion tensor imaging of the optic nerve in subacute anterior ischemic optic neuropathy at 3T.

BACKGROUND AND PURPOSE DTI can provide in vivo information about the pathology of optic nerve disease, but there is no study of DTI in the setting of ION, the most frequent acute optic neuropathies in patients over 50 years of age. Our aim was to investigate the potential of DTI in the diagnosis of subacute AION at 3T. MATERIALS AND METHODS Twenty-six patients with unilateral AION and 15 heal...

Reduced Field-of-View Diffusion Tensor Imaging of the Optic Nerve in Retinitis Pigmentosa at 3T.

BACKGROUND AND PURPOSE Diffusion tensor imaging may reflect pathology of the optic nerve; however, the ability of DTI to evaluate alterations of the optic nerve in retinitis pigmentosa has not yet been assessed, to our knowledge. The aim of this study was to investigate the diagnostic potential of reduced FOV-DTI in optic neuropathy of retinitis pigmentosa at 3T. MATERIALS AND METHODS Thirty-...

The efficacy of optic nerve sheath decompression for anterior ischemic optic neuropathy and other optic neuropathies.

First proposed by De Wecker! in 1872 as a treatment for neuroretinitis, optic nerve sheath decompression (or fenestration) is an operation that has caused much controversy. This surgical therapy was not seriously considered until Davidson" and Smith, Hoyt, and Newton" reintroduced it in 1969 as an alternative therapy for chronic disk edema. Over the next 19 years, however, only about 60 cases o...

Diffusion tensor imaging of optic nerve and optic radiation in primary chronic angle-closure glaucoma using 3T magnetic resonance imaging.

AIM To evaluate the value of quantitative diffusion tensor imaging (DTI) in assessing the axonal and myelin damage of the optic nerves and optic radiations in patients with chronic primary angle-closure glaucoma (PACG) by using high-field magnetic resonance (MR) imaging (3T). METHODS Twenty patients with bilateral chronic PACG and twenty age- and sex matched disease-free control subjects were...

transvitreal optic neurotomy for non-arteritic anterior ischemic optic neuropathy

purpose: to evaluate the role of transvitreal optic neurotomy (ton) in the management of non-arteritic anterior ischemic optic neurotomy (naion). methods: sixteen eyes of 16 patients with recent onset naion (less than six weeks duration) were included in this single-masked randomized controlled trial. the patients were randomized to ton (8 eyes) versus observation alone (8 eyes). pre- and posto...
