purpose : to evaluate orbital blood flow velocities and optic nerve diameter with doppler and gray-scale sonography in patients with acute unilateral optic neuritis (on) methods : orbital doppler and gray-scale sonography was performed in 46 eyes of 23 patients aged 19-47 with acute unilateral on. on was diagnosed by an ophthalmologist on the basis of clinical presentation, presence of decrease...

Objective to investigate whether optical coherence tomography (OCT) could demonstrate axonal loss through thinning of the retinal nerve fiber layer (RNFL) in multiple sclerosis (MS) patients. Furthermore, the degree of RNFL loss was compared in the different MS subgroups (with or without optic neuritis, affected or fellow eye, single episode or recurrent optic neuritis, relapsing remitting or p...

Background: Optic neuritis typically presents with acute or subacute onset of mild profound blurring vision. There are very limited reports regarding optic in the paediatric population compared to adults from South Asian region. We report a series 7 cases neuritis.
 Methods: All aged less than 12 years old 2016 were studied retrospectively.
 Results: Out 44 patients neuritis, them age...

The aim of this review is to summarize the latest information about optic neuritis, its differential diagnosis and management. Optic Neuritis (ON) is defined as inflammation of the optic nerve, which is mostly idiopathic. However it can be associated with variable causes (demyelinating lesions, autoimmune disorders, infectious and inflammatory conditions). Out of these, multiple sclerosis (MS) ...

BACKGROUND Optic perineuritis is an uncommon variety of orbital inflammatory disease that is distinct from demyelinating optic neuritis. OBJECTIVE To describe the clinical and radiographic features of idiopathic optic perineuritis, with particular emphasis on those features that help to distinguish this condition from optic neuritis. METHODS We reviewed the medical records of 14 patients wi...

Monocular temporal hemianopia was identified in 24 patients. The field of the fellow eye was normal. Computed tomography or magnetic resonance imaging showed juxta-sellar lesions in 19 patients. Fifteen had pituitary adenomas, two had tuberculum sella meningiomas, one a craniopharyngioma, and one an astrocytoma. One patient had optic neuritis. A relative afferent pupillary defect (RAPD) was det...

Angiostrongyliasis, caused by Angiostrongylus cantonensis infection, is a food-borne parasitic disease. Its larvae evoke eosinophilic inflammation in the central nervous system, but can also cause pathological changes in the eyes. Among ocular angiostrongyliasis cases, the incidence of optic neuritis is low and only few sporadic reports exist. Some patients with optic neuritis developed obvious...

Acute demyelinating optic neuritis associated with multiple sclerosis (MS) is the most common cause of inflammation of the optic nerve. The Optic Neuritis Treatment Trial (ONTT) has provided important clinical data on the use of corticosteroids, and demonstrated that patients with characteristic inflammatory lesions within the brain on magnetic resonance imaging had a greater chance of developi...

PURPOSE To devise a practical technique for high-resolution evaluation of the anterior optic apparatus using a phased-array surface coil system, and to evaluate this system in patients with suspected optic pathway abnormalities. METHODS A four-element phased-array coil pair was placed on each side of the head, and signal-to-noise measurements were obtained using a head phantom. Comparison bet...
