Transorbital Sonography in Acute Optic Neuritis: A Case-Control Study [PDF]
, 2014 BACKGROUND AND PURPOSE: Acute unilateral optic neuritis is associated with a thickening of the retrobulbar portion of the optic nerve as revealed by transorbital sonography, but no comparison has been made between nerve sheath diameter and optic nerve ...

Masquerading optic neuritis [PDF]
BMJ Case Reports, 2015 A 54-year-old woman presented to the ophthalmology emergency department with a 10-day history of blurred vision. The best-corrected visual acuities and Ishihara colour vision were bilaterally reduced with a left relative afferent pupillary defect. Slit-lamp examination was otherwise normal.

Magnifying absolute instruments for optically homogeneous regions [PDF]
Phys. Rev. A 84, 031801(R) (2011), 2011 We propose a class of magnifying absolute optical instruments with a positive isotropic refractive index. They create magnified stigmatic images, either virtual or real, of optically homogeneous three-dimensional spatial regions within geometrical optics.

Monitoring retinal changes with optical coherence tomography predicts neuronal loss in experimental autoimmune encephalomyelitis. [PDF]
, 2019 BACKGROUND:Retinal optical coherence tomography (OCT) is a clinical and research tool in multiple sclerosis, where it has shown significant retinal nerve fiber (RNFL) and ganglion cell (RGC) layer thinning, while postmortem studies have reported RGC loss.

Indian Journal of Ophthalmology, 2011 Optic neuritis is an inflammatory condition of the optic nerve characterized by a sudden onset of unilateral visual loss, usually affecting young females. Demyelination associated with multiple sclerosis (MS) is the most common cause in regions where MS is prevalent; while in other places, there are a substantial proportion of cases where infective or ...

Myelin Oligodendrocyte Glycoprotein–specific T Cell Receptor Transgenic Mice Develop Spontaneous Autoimmune Optic Neuritis [PDF]
, 2003 Multiple sclerosis (MS) is considered to be an autoimmune disease of the central nervous system (CNS) that in many patients first presents clinically as optic neuritis. The relationship of optic neuritis to MS is not well understood.
