Inflammation of the optic nerve. Commonly associated conditions include autoimmune disorders such as MULTIPLE SCLEROSIS, infections, and granulomatous diseases. Clinical features include retro-orbital pain that is aggravated by eye movement, loss of color vision, and contrast sensitivity that may progress to severe visual loss, an afferent pupillary defect (Marcus-Gunn pupil), and in some instances optic disc hyperemia and swelling. Inflammation may occur in the portion of the nerve within the globe (neuropapillitis or anterior optic neuritis) or the portion behind the globe (retrobulbar neuritis or posterior optic neuritis).
A general term indicating inflammation of a peripheral or cranial nerve. Clinical manifestation may include PAIN; PARESTHESIAS; PARESIS; or HYPESTHESIA.
An experimental animal model for the demyelinating disease of GUILLAINE-BARRE SYNDROME. In the most frequently used protocol, animals are injected with a peripheral nerve tissue protein homogenate. After approximately 2 weeks the animals develop a neuropathy secondary to a T cell-mediated autoimmune response directed towards the MYELIN P2 PROTEIN in peripheral nerves. Pathologic findings include a perivascular accumulation of macrophages and T lymphocytes in the peripheral nervous system, similar to that seen in the Guillaine-Barre syndrome.

The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.
A syndrome characterized by acute OPTIC NEURITIS; MYELITIS, TRANSVERSE; demyelinating and/or necrotizing lesions in the OPTIC NERVES and SPINAL CORD; and presence of specific autoantibodies to AQUAPORIN 4.
An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)

The electric response evoked in the cerebral cortex by visual stimulation or stimulation of the visual pathways.
Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.
Idiopathic inflammation of the VESTIBULAR NERVE, characterized clinically by the acute or subacute onset of VERTIGO; NAUSEA; and imbalance. The COCHLEAR NERVE is typically spared and HEARING LOSS and TINNITUS do not usually occur. Symptoms usually resolve over a period of days to weeks. (Adams et al., Principles of Neurology, 6th ed, p304)
Atrophy of the optic disk which may be congenital or acquired. This condition indicates a deficiency in the number of nerve fibers which arise in the RETINA and converge to form the OPTIC DISK; OPTIC NERVE; OPTIC CHIASM; and optic tracts. GLAUCOMA; ISCHEMIA; inflammation, a chronic elevation of intracranial pressure, toxins, optic nerve compression, and inherited conditions (see OPTIC ATROPHIES, HEREDITARY) are relatively common causes of this condition.
Neurons of the innermost layer of the retina, the internal plexiform layer. They are of variable sizes and shapes, and their axons project via the OPTIC NERVE to the brain. A small subset of these cells act as photoreceptors with projections to the SUPRACHIASMATIC NUCLEUS, the center for regulating CIRCADIAN RHYTHM.
A localized defect in the visual field bordered by an area of normal vision. This occurs with a variety of EYE DISEASES (e.g., RETINAL DISEASES and GLAUCOMA); OPTIC NERVE DISEASES, and other conditions.

These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132).
A PREDNISOLONE derivative with similar anti-inflammatory action.
The X-shaped structure formed by the meeting of the two optic nerves. At the optic chiasm the fibers from the medial part of each retina cross to project to the other side of the brain while the lateral retinal fibers continue on the same side. As a result each half of the brain receives information about the contralateral visual field from both eyes.
Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy.

A syndrome associated with inflammation of the BRACHIAL PLEXUS. Clinical features include severe pain in the shoulder region which may be accompanied by MUSCLE WEAKNESS and loss of sensation in the upper extremity. This condition may be associated with VIRUS DISEASES; IMMUNIZATION; SURGERY; heroin use (see HEROIN DEPENDENCE); and other conditions. The term brachial neuralgia generally refers to pain associated with brachial plexus injury. (From Adams et al., Principles of Neurology, 6th ed, pp1355-6)
Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA). Severity of hereditary defects of color vision depends on the degree of mutation of the ROD OPSINS genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue.
Inflammation of a transverse portion of the spinal cord characterized by acute or subacute segmental demyelination or necrosis. The condition may occur sporadically, follow an infection or vaccination, or present as a paraneoplastic syndrome (see also ENCEPHALOMYELITIS, ACUTE DISSEMINATED). Clinical manifestations include motor weakness, sensory loss, and incontinence. (Adams et al., Principles of Neurology, 6th ed, pp1242-6)
Injuries to the optic nerve induced by a trauma to the face or head. These may occur with closed or penetrating injuries. Relatively minor compression of the superior aspect of orbit may also result in trauma to the optic nerve. Clinical manifestations may include visual loss, PAPILLEDEMA, and an afferent pupillary defect.

Constriction of the pupil in response to light stimulation of the retina. It refers also to any reflex involving the iris, with resultant alteration of the diameter of the pupil. (Cline et al., Dictionary of Visual Science, 4th ed)
An experimental animal model for central nervous system demyelinating disease. Inoculation with a white matter emulsion combined with FREUND'S ADJUVANT, myelin basic protein, or purified central myelin triggers a T cell-mediated immune response directed towards central myelin. The pathologic features are similar to MULTIPLE SCLEROSIS, including perivascular and periventricular foci of inflammation and demyelination. Subpial demyelination underlying meningeal infiltrations also occurs, which is also a feature of ENCEPHALOMYELITIS, ACUTE DISSEMINATED. Passive immunization with T-cells from an afflicted animal to a normal animal also induces this condition. (From Immunol Res 1998;17(1-2):217-27; Raine CS, Textbook of Neuropathology, 2nd ed, p604-5)

Deterioration of the sheath in DEMYELINATING DISEASES is a serious clinical problem.

mtDNA haplogroup J: a contributing factor of optic neuritis. (1/359)

Optic neuritis frequently occurs in multiple sclerosis (MS), and shares several similarities with the optic neuritis of Leber's hereditary optic neuropathy (LHON), which is mainly due to maternally transmitted mitochondrial DNA (mtDNA) mutations. Our report shows for the first time that a mitochondrial DNA background could influence the clinical expression of MS. One European mtDNA haplogroup was found only in MS patients with optic neuritis but not in MS patients without visual symptoms. Therefore, we hypothesize that mtDNA haplogroup J might constitute a risk factor for optic neuritis occurrence when it is coincidentally associated with MS, but not be a risk factor for developing MS per se as suggested previously.  (+info)

Correlation between morphological and functional retinal impairment in multiple sclerosis patients. (2/359)

PURPOSE: To assess whether a correlation exists between optic nerve fiber layer (NFL) thickness and the retinal or visual pathway function in multiple sclerosis (MS) patients previously affected by optic neuritis. METHODS: Fourteen patients with a diagnosis of definite MS were examined. All had been affected by optic neuritis (MSON) with complete recovery of visual acuity (14 eyes included in study). These were compared with 14 eyes from 14 age-matched control subjects. NFL thickness was measured by optical coherence tomography (OCT). Three different measurements in each quadrant (superior, inferior, nasal, and temporal) were taken and averaged. The data in all quadrants (12 values averaged) were identified as NFL Overall, whereas the data obtained in the temporal quadrant only (3 values averaged) were identified as NFL Temporal. Retinal and visual pathway function was assessed by simultaneously recording pattern electroretinograms (PERGs) and visual evoked potentials (VEPs) using high-contrast (80%) checkerboard stimuli subtending 15 minutes and 60 minutes of the visual arc (min arc) and reversed at the rate of two reversals per second. RESULTS: In MSON eyes there was a significant (P < 0.01) reduction in NFL thickness in both NFL Overall and NFL Temporal evaluations compared with the values observed in control eyes. PERG, (15-min arc checks) and VEP (15-min arc and 60-min arc checks), showed a significant (P < 0.01) delay in latency and reduction in amplitude. NFL Overall and NFL Temporal values were significantly correlated (P < 0.01) to the PERG P50 latency and P50 to N95 amplitude recorded with 15-min arc checks. No correlations (P > 0.01) between NFL values and the other electrophysiological data (PERG recorded with 60-min arc checks and VEP recorded with 15-min arc and 60-min arc checks) were found. CONCLUSIONS: There is a correlation between PERG changes and NFL thickness in MS patients previously affected by optic neuritis, but there is no correlation between VEP changes and NFL thickness.  (+info)

Lack of restriction of T cell receptor beta variable gene usage in cerebrospinal fluid lymphocytes in acute optic neuritis. (3/359)

OBJECTIVES: There have been many studies reporting restricted patterns of T cell receptor usage in established multiple sclerosis and these have led to clinical trials of immunomodulation directed at deleting clonal T cell populations. The present study aims to test the hypothesis that highly restricted T cell populations are also present in the CSF in the earliest clinical stages of acute demyelinating disease of the CNS. METHODS: T cell receptor Vbeta (TCRBV) gene expression was studied in CSF and blood in nine patients with acute optic neuritis within 7 days of onset of symptoms, six patients with an acute relapse of multiple sclerosis, and 13 control subjects. RNA was extracted and cDNA synthesised from unstimulated CSF and blood lymphocytes, and TCRBV gene segments were amplified from the cDNA by polymerase chain reaction (PCR) using 21 family specific primers. PCR products were separated by polyacrylamide gel electrophoresis and detected via a labelled oligonucleotide probe. A semiquantitative analysis of band intensity was performed by laser densitometry. RESULTS: TCRBV mRNA was detected in the CSF of eight of nine patients with optic neuritis, six of six patients with multiple sclerosis, and five of 13 controls, and was closely correlated with the presence of oligoclonal IgG. Usage of a single TCRBV family was demonstrated in two of nine patients with optic neuritis and two of six patients with multiple sclerosis. The number of TCRBV families expressed in the other patients ranged between 5 and 15 (optic neuritis) and 4 and 17 (multiple sclerosis). CONCLUSIONS: There is a relative lack of restriction of TCRBV usage by CSF lymphocytes in the very earliest stages (<7 days) of acute optic neuritis. This may imply either that multiple sclerosis is not a monoclonal disease even at onset, or that the autoimmune response has widened before the disease becomes clinically evident. This may have important consequences for the design of immune therapies in multiple sclerosis. Further studies are required to determine whether the CSF T cell repertoire at presentation has prognostic importance. Longitudinal studies are required to follow the CSF T cell repertoire from the time of presentation and to determine whether it may have prognostic significance.  (+info)

Demonstration of Bartonella grahamii DNA in ocular fluids of a patient with neuroretinitis. (4/359)

We describe the clinical and laboratory features of a 55-year-old human immunodeficiency virus-negative female patient who presented with bilateral intraocular inflammatory disease (neuroretinitis type) and behavioral changes caused by a Bartonella grahamii infection. Diagnosis was based on the PCR analysis of DNA extracted from the intraocular fluids. DNA analysis of the PCR product revealed a 100% identity with the 16S rRNA gene sequence of B. grahamii. The patient was successfully treated with doxycycline (200 mg/day) and rifampin (600 mg/day) for 4 weeks. This is the first report that demonstrates the presence of a Bartonella species in the intraocular fluids of a nonimmunocompromised patient and that indicates that B. grahamii is pathogenic for humans.  (+info)

Combined fat- and water-suppressed MR imaging of orbital tumors. (5/359)

BACKGROUND AND PURPOSE: The use of a high-resolution T2-weighted MR sequence, which suppresses signal from both fat and water, has been shown to be highly effective for depicting areas of inflammatory damage within the optic nerve. The ability of this sequence to show neoplastic and inflammatory orbital lesions, which may mimic neuritis, is unknown. This study was designed to examine the characteristics of such a sequence for the investigation of orbital mass lesions. METHODS: Twenty-eight patients with known or suspected mass lesions of the orbit and six healthy volunteers were recruited for study. Imaging was performed with a 1.5-T MR unit. Participants were examined by selective partial inversion recovery (SPIR) sequences with T2-weighted fast spin-echo acquisition, selective partial inversion recovery/fluid attenuated inversion recovery (SPIR/FLAIR) sequences with fast spin-echo acquisition, short tau inversion recovery (STIR) sequences with fast spin-echo acquisition, and SPIR sequences with contrast-enhanced T1-weighted fast spin-echo acquisition. Two neuroradiologists, using a randomised, blinded method, scored images for lesion presence and extent. Lesion extent was defined as the number of images with visible abnormality, and was compared with the standard of reference established at a later date by consensus review of all imaging sequences. The ability of the sequences to show the presence and extent of pathologic lesions was compared. RESULTS: The SPIR/FLAIR sequence showed both the presence and extent of orbital masses significantly better than did either STIR or T2-weighted SPIR sequences (P<.01 and P<.001, respectively). Contrast-enhanced T1-weighted SPIR images ranked better than SPIR/FLAIR images, although the difference failed to reach statistical significance. In the orbital apex, the SPIR/FLAIR technique was superior to all other techniques used. This reflected its ability to distinguish enhancing, pathologic lesions from enhancing, normal anatomy. CONCLUSION: SPIR/FLAIR is an appropriate screening technique for orbital masses and offers significant advantages over currently used fat-suppressed sequences for the investigation of orbital disease.  (+info)

Multiple sclerosis: the disease and its manifestations. (6/359)

Multiple sclerosis is an immune-mediated inflammatory demyelinating disease of the central nervous system clinically characterized by relapses and remissions of neurological disturbance. A typical relapse, exemplified by optic neuritis, increases in severity over a week or two and after approximately one month begins to remit. Resolution takes place over the course of two to three months. In the early stages, clinical recovery is virtually complete, though persistent abnormalities of conduction can usually be detected by evoked potential techniques and persistent structural abnormalities can be detected by magnetic resonance imaging (MRI). These techniques, together with cerebrospinal fluid examination for oligoclonal IgG, provide supporting evidence for the diagnosis which, in the absence of a specific test, nevertheless remains primarily clinical. The course of the disease is very variable, but after a number of years neurological deficit begins to accumulate after each relapse. In most patients, the relapsing and remitting phase of the disease is followed by a phase of continuous progression of disability. Cognitive disturbances can be detected in many patients even quite early in the course of the illness. Deficits in attention, memory and executive skills may be prominent and tend to become increasingly prominent as neurological deficit increases, although this is not always the case. There is some correlation between the extent of MRI abnormalities in the cerebral white matter and the severity of cognitive deficit. Depression and anxiety are commonly experienced but are poorly correlated to the lesion load seen on MRI. In contrast, the much rarer psychotic symptoms, euphoria and emotional lability are closely linked to the severity of white matter disease.  (+info)

Response variability in the visual field: comparison of optic neuritis, glaucoma, ocular hypertension, and normal eyes. (7/359)

PURPOSE: To compare the relationship between sensitivity and response variability in the visual field of normal eyes and eyes with optic neuritis (ON), glaucoma (POAG), and ocular hypertension (OHT). METHODS: Frequency-of-seeing (FOS) data were collected from four visual field locations in one eye of 71 subjects (12 ON, 25 POAG, 11 OHT, and 23 normal), using a constant stimulus method on an Henson 4000 perimeter (Tinsley Instruments, Croydon, UK). At each location, at least 20 stimuli (subtending 0.5 degrees) were presented for 200 ms at six or more intensities above and below the estimated threshold. The mean and SD of the probit fitted cumulative Normal function were used to estimate sensitivity and response variability. Cluster regression analysis was carried out to determine whether there were differences in the sensitivity-log (variability) relationship between the four groups. RESULTS: Variability was found to increase with decreased sensitivity for all four groups. The combined data from the four groups was well represented (R2 = 0.57) by the function log(e)(SD) = A.sensitivity (dB) + B, where the constants A and B were -0.081 (SE, +/-0.005) and 3.27 (SE, +/-0.15), respectively. Including other statistically significant covariates (false-negative errors, P = 0.004) and factors (diagnosis, P = 0.005) into the model increased the proportion of explained variance to 62% (R2 = 0.62). Stimulus eccentricity (P = 0.34), patient age (P = 0.33), fixation loss rate (P = 0.10), and false-positive rate (P = 0.66) did not reach statistical significance as additional predictors of response variability. CONCLUSIONS: The relationship between response variability and sensitivity is similar for ON, POAG, OHT, and normal eyes. These results provide supporting evidence for the hypothesis that response variability is dependent on functional ganglion cell density.  (+info)

Recovery from optic neuritis is associated with a change in the distribution of cerebral response to visual stimulation: a functional magnetic resonance imaging study. (8/359)

OBJECTIVES: Recovery to normal or near normal visual acuity is usual after acute demyelinating optic neuritis, despite the frequent persistence of conduction abnormalities as evidenced by the visual evoked potential (VEP). This raises the possibility that cortical adaptation to a persistently abnormal input contributes to the recovery process. The objective of this study was to investigate the pattern of cerebral response to a simple visual stimulus in recovered patients in comparison to normal subjects. METHODS: Functional magnetic resonance imaging (fMRI) was used to study the brain activation pattern induced by a periodic monocular 8Hz photic stimulus in seven patients who had recovered from a single episode of acute unilateral optic neuritis, and in seven normal controls. VEPs and structural optic nerve MRI were performed on patients. RESULTS: Stimulation of either eye in controls activated only the occipital visual cortex. However, in patients, stimulation of the recovered eye also induced extensive activation in other areas including the insula-claustrum, lateral temporal and posterior parietal cortices, and thalamus; stimulation of the clinically unaffected eye activated visual cortex and right insula-claustrum only. The volume of extraoccipital activation in patients was strongly correlated with VEP latency (r = 0.71, p = 0.005). CONCLUSIONS: The extraoccipital areas that were activated in patients all have extensive visual connections, and some have been proposed as sites of multimodal sensory integration. The results indicate a functional reorganisation of the cerebral response to simple visual stimuli after optic neuritis that may represent an adaptive response to a persistently abnormal input. Whether this is a necessary part of the recovery process remains to be determined.  (+info)

Purpose : Nonarteritic anterior ischemic optic neuropathy (NAION) and optic neuritis are the two most common acute optic neuropathies. OCT angiography is a new tool that can evaluate the density of the radial peripapillary capillary network, which has been shown to be decreased in various chronic optic neuropathies. The goal of this study was to evaluate OCT and OCT angiographys ability to differentiate optic neuritis and NAION, and predict visual outcomes. Methods : We performed a cross-sectional, observational study of patients with unilateral optic neuritis or NAION who presented between 2015 and 2016. Patients were included if they had unilateral optic neuritis or NAION and had OCT (Cirrus) and OCT angiography (Optovue) done at least 3 months after onset. Because a normative database for OCT angiography has not been established, we used the inter-eye difference as an approximation of change. The retinal nerve fiber layer (RNFL) and peripapillary vessel density were compared between optic ...
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 autoimmune causes are seen. Optic Neuritis Treatment Trial (ONTT) was the first major study that provided information on the natural history, role of steroids in treatment and risk of development of MS. Subsequently, numerous clinical trials have evaluated different modalities of management of optic neuritis and MS. The Controlled High-Risk Subjects Avonex Multiple Sclerosis Prevention Study (CHAMPS); the Prevention of Relapses and Disability by Interferon β-1a Subcutaneously in Multiple Sclerosis (PRISMS) Trial; and, most recently, the Betaferon in Newly Emerging Multiple Sclerosis for Initial Treatment (BENEFIT) Study have provided large ...

Purpose : In this study, the performance of a suite of rapid smartphone vision tests were evaluated for monitoring visual function in patients with multiple sclerosis with prior optic neuritis (MS+ON), without prior optic neuritis (MS-ON), and normal subjects (N). Methods : In this pilot study, 56 patients with MS (relapse remitting MS and secondary progressive MS) with prior optic neuritis (MS+ON; n=21) or without prior optic neuritis (MS-ON; n=35) and 34 age-matched controls were tested in the Aalborg, Denmark University Hospital Multilple Sclerosis Clinic using a battery of smartphone visual function tests (Landolt C acuity, Landolt C contrast sensitivity, critical flicker fusion contrast threshold at 7.5 and 15Hz, related to visual conduction speed). Testing was performed with the patient wearing their glasses. One eye was used for statistical comparisons between groups (ANOVA rank test with pairwise multiple comparisons using Dunns method). Results : Each smartphone test took approximately ...
Autoimmune optic neuropathy (AON), sometimes called autoimmune optic neuritis, may be a forme fruste of systemic lupus erythematosus (SLE) associated optic neuropathy. AON is more than the presence of any optic neuritis in a patient with an autoimmune process, as it describes a relatively specific clinical syndrome. AON is characterized by chronically progressive or recurrent vision loss associated with serological evidence of autoimmunity. Specifically, this term has been suggested for cases of optic neuritis with serological evidence of vasculitis by positive ANA, despite the lack of meeting criteria for SLE. The clinical manifestations include progressive vision loss that tends to be steroid-responsive and steroid dependent. Patients with defined SLE that go on to develop optic neuritis should be better identified as lupus optic neuritis. AON was first described in 1982. It presents with visual loss and signs of optic nerve dysfunction, such as loss of color vision, afferent pupil defect, and ...

Introduction: To report our experience in management of patients with optic neuritis. The effects of brain magnetic resonance imaging and visual evoked potential on management were investigated. Methods: This is a four years clinical trial that included patients presenting with first attack of optic neuritis older than 16 years with visual acuity of less than 6/60 and presentation within first week of illness. Brain magnetic resonance imaging and visual evoked potentials were done for all patients. Patients were classified into three groups. First group received placebo, second received oral steroids and third received intravenous and oral steroids. Primary outcome measure was improvement in vi sual acuity.. Results: A total number of 150 patients were enrolled in the study. Ocular pain was seen 127 patients Relative afferent pupillary defect in 142 patients and color vision impairment in 131 patients. Abnormal MRI findings were seen in 84 patients. Pattern reversal VEP was abnormal in all ...
Causes:. When light that reflects off an object enters the clear outer part of a persons eyeball (cornea) and passes through the lens bringing the light into focus on the nerve cell layer of their eye (retina), the complex procedure of sight starts. As soon as the light hits the retina, electrical impulses are generated and carried along the optic nerve to the persons brain, where the impulses are converted into visual information. The optic nerve is a bundle of nerve fibers covered by a fatty insulated material named myelin helping electrical impulses to speed along the nerve. When the immune system attacks myelin covering the optic nerve causing inflammation and damage, optic neuritis develops young adults. Why a persons immune system attacks its own tissue is unknown. Two autoimmune conditions are usually related to optic neuritis, they are: ...
When a neurologic condition develops after vaccination of a patient, the causal relationship is difficult to determine. We report an unusual case in which neurologic signs occurred in a previously healthy child after both doses of H1N1 2009 influenza vaccine, culminating in bilateral optic neuritis and disseminated encephalomyelitis. A causal association is more likely with repeated injury following influenza vaccination ...
Background and purpose: Optic neuritis is one of the common causes of unilateral or bilateral visual loss. The most common cause of this disorder is demyelinating disease of the central nervous system (CNS) and most of the patients with optic neuritis will present other signs of multiple sclerosis (MS). The ...

The first symptom of optic neuritis in a child is most commonly a rapid, often profound decrease in vision (visual acuity less than 20/400). It can occur in both eyes and it may be worse in one eye than another. Patients may also have headaches and pain with eye movement. Many children with optic neuritis have a history of a fever, flu-like illness, or immunizations 1-2 weeks prior to the onset of the decreased vision.. ...

A Randomized, Double-Blind, Parallel-Group, Placebo Controlled Trial to Assess the Efficacy, Safety, Tolerability, and Pharmacokinetics of Clemastine Fumarate as a Remyelinating Agent in Acute Optic Neuritis. This Phase II clinical trial will assess the efficacy, safety, and tolerability of an identified compound in the promotion of remyelination in patients experiencing acute optic neuritis. This investigational drug was approved for the treatment of allergic rhinitis by the Food and Drug Administration (FDA) in 1977. Since then, the medication has been identified at UCSF as a compound that potentially enhances oligodendrocyte differentiation and remyelination. However, it is not approved as a therapy for optic neuritis.. Study participants will be asked to come to the UCSF Multiple Sclerosis Center at least 5 times over approximately 9 months. Participation will include an initial screening visit to determine eligibility, and 4 follow-up visits (at 1 week, 1 month, 3 months, and 9 months after ...
METHODS: In this multicentre, cohort study, we collected data about patients (age ≥16 years old) with clinically isolated syndrome, relapsing-remitting multiple sclerosis, and progressive multiple sclerosis. Patients were recruited from centres in Spain, Italy, France, Germany, Czech Republic, Netherlands, Canada, and the USA, with the first cohort starting in 2008 and the latest cohort starting in 2013. We assessed disability worsening using the Expanded Disability Status Scale (EDSS). The pRNFL thickness and macular volume were assessed once at study entry (baseline) by optical coherence tomography (OCT) and was calculated as the mean value of both eyes without optic neuritis for patients without a history of optic neuritis or the value of the non-optic neuritis eye for patients with previous unilateral optic neuritis. Researchers who did the OCT at baseline were masked to EDSS results and the researchers assessing disability with EDSS were masked to OCT results. We estimated the association ...
The retina lies in the back of the eye and is a multi-layered tissue which detects visual images. These images are transmitted to the brain through approximately 1 million tiny nerve fibers. These nerve fibers converge in the back of the eye, before going to the brain, into a bundle called the optic nerve. If some or all of the nerve fibers are damaged, visual capability deteriorates.. When the optic nerve becomes inflamed, this condition is called optic neuritis. The nerve tissue becomes swollen and red, and the nerve fibers do not work properly. If many of the nerve fibers are involved, the vision may be dramatically affected, but if the optic neuritis is mild, vision is nearly normal. Optic neuritis can be caused by other diseases and conditions and may affect the optic nerve of one or both eyes.. Some people, especially children, develop optic neuritis following a viral illness such as mumps, measles, or a cold. In others, optic neuritis may occur as a sign of a more serious neurological ...

Patients aged 18-65 with acute demyelinating optic neuritis where treatment with high dose corticosteroids are already been chosen by the patient and the diagnosing physician will be contacted for screening and enrollment. Patients will then be randomized to receive equivalent doses of either intravenous (IV) or oral corticosteroid treatment. Optic nerve function assessments will be compared at baseline, prior to treatment, one and six months post corticosteroid treatment. This will allow for a comparison on whether the route of medication plays a role in the effectiveness of treatment with high dose corticosteroids ...
This study provides Class I evidence that simvastatin 80 mg daily is well tolerated and possibly effective in patients with acute ON.
About half of people with MS experience at some point in their life a condition called acute optic neuritis, in which the nerve carrying vision from the eye to the brain gets inflamed, said study author Raj Kapoor, MD, with the National Hospital for Neurology and Neurosurgery in London, England. The condition can cause sudden total or partial blindness, foggy or blackened vision and pain. Even though eyesight can recover eventually, each attack still damages the nerve and the eye.. For the study, the researchers randomly selected 86 people with acute optic neuritis within two weeks of having symptoms to receive either the epilepsy drug phenytoin or a placebo for three months. The researchers then used medical imaging to measure the thickness of the retina, the light sensitive nerve layer at the back of the eye at the beginning of the study and then six months later. Each patients eyesight (including sharpness and color perception) was also tested.. The study found on average that the group ...

We found that an episode of acute ON can result in extensive neuroaxonal retinal damage of the ipsilateral eye, confirming previous longitudinal reports.17,18 Significant GCIP thinning was already detectable at 1 month after ON and also at all subsequent time points.. The status of the retina distal to GCIP beyond 6 months post-ON has previously not been documented. We measured a small but significant increase in INL thickness in the clinically (seemingly) unaffected NON eyes at month 12, suggestive of bilateral retinal pathology in clinically unilateral ON.. Similarly, a significant intereye difference between month 1 INL thickness in ON eyes and baseline contralateral INL thickness was observed. Although the detected changes are numerically small, the INL thickness increase in the ON eyes recorded was similar in magnitude to previous findings, including a large meta-analysis.12 All these previously reported changes to INL thickness, including the current findings, are below the axial ...

Acute visual loss. Optic neuritis (ON) is the most common acute optic neuropathy below the age of 45. The annual incidence is about 1 per 100,000 in low risk populations. It presents typically as a progressive painful loss of vision (worse with eye movements) in young adults that recovers greatly over months. In the acute phase, findings include visual field defects (central or paracentral vision loss or altitudinal defects), afferent pupillary defect, disproportionate loss of color vision (red desaturation), a reduced visual acuity, abnormal VEPs. In up to 60% the optic disc may be normal (retrobulbar neuritis). When there is swelling of the optic disk the term papillitis is used. Optic neuritis can be unilateral or bilateral. Unilateral ON is very often reversible often seen under the age of 40. Following resolution, in practically all patients subtle residual defects may persist such as defective color vision, depth perception, and contrast sensitivity. In bilateral ON there is often lack of ...

Well, the fun never stops. The past few weeks Ive been a hard one to get ahold of, so I thought Id fill people in on whats been up. Last week I woke up and couldnt really see out of one eye. Bummer. So I got my butt to the doc. They tell us in school that nothing sends a patient in faster than visual changes and they are right. You dont realize how much you truly use your eyes until they arent so much doing their job. I was amazed at how quickly I got shuttled off to the specialist, and to be honest it freaked me out just a bit. But ultimately they got me figured out and I have something called optic neuritis. Basically my immune system got all pissy at my optic nerve and decided to tear the myelin covering off of it. The good news: 92% of people who get this recover full vision and the pain that is associated with eye movements almost uniformly goes away. The bad news, I cant drive and since its a problem with the nerve and not the lens, my glasses dont do a thing. So, although its ...

I have the chronic form of Guillian Barres syndrome, so my it was highly reccommended that my daugther receive her Flu Shot. She was unable to have the flu mist due to the live virus causing a relapse in my condition. Anyway...long story short. She had the vaccine about 2 weeks ago. Shortly after she began complaining of seeing yellow out of her right eye. I brought her in to her peds doc yesterday and they found that she has developed red/green color blindness in her right eye. She saw an optometrist this morning and was noted to have significant changes in her vision since her last exam (larger than he has seen in any child). No one seems to know what is wrong at this point. I have been researching and I came across Optic Neuritis. With her autoimmune history and mine I thought this is a high possibility. I am wondering what sort of symptoms you developed. And if you have any advice for me. Thanks in ...

Recent neuroimaging studies show that brain abnormalities in neuromyelitis optica (NMO) are more frequent than earlier described. Yet, more research considering multiple aspects of NMO is necessary to better understand these abnormalities. A clinical feature of relapsing NMO (RNMO) is that the incremental disability is attack-related. Therefore, association between the attack-related process and neuroimaging might be expected. On the other hand, the immunopathological analysis of NMO lesions has suggested that CNS microvasculature could be an early disease target, which could alter brain perfusion. Brain tissue volume changes accompanying perfusion alteration could also be expected throughout the attack-related process. The aim of this study was to investigate in RNMO patients, by voxel-based correlation analysis, the assumed associations between regional brain white (WMV) and grey matter volumes (GMV) and/or perfusion on one side, and the number of optic neuritis (ON) attacks, myelitis attacks and/or

Chronic relapsing inflammatory optic neuropathy (CRION), sometimes called chronic relapsing inflammatory optic neuritis, is a form of recurrent optic neuritis that is steroid responsive. Patients typically present with pain associated with visual loss. CRION is a diagnosis of exclusion, and other demyelinating, autoimmune, and systemic causes should be ruled out. Early recognition is crucial given risks for severe visual loss and because it is treatable with immunosuppressive treatment such as steroids. Relapse that occurs after reducing or stopping steroids is a characteristic feature Pain, visual loss, relapse, and steroid response are typical of CRION. Ocular pain is typical, although there are some cases with no reported pain. Bilateral severe visual loss (simultaneous or sequential) usually occurs, but there are reports of unilateral visual loss. Patients can have an associated relative afferent pupillary defect. CRION is associated with at least one relapse, and up to 18 relapses have been ...
There is good evidence that corticosteroid therapy accelerates the recovery from relapse. The exact mode of action of corticosteroids in multiple sclerosis is unclear. However, there are several potential modes of action, which include reducing oedema, stabilising the blood-brain barrier, decreasing pro-inflammatory cytokines, and inducing T cell apoptosis.48 Efficacy was shown in early studies using intramuscular ACTH though this practice has now stopped. Intravenous methylprednisolone has been shown to accelerate recovery rate,49,50 and to be effective as ACTH.51,52. The comparative efficacy of intravenous and oral corticosteroids has been more controversial. The largest study to date was a randomised, placebo controlled study of intravenous methylprednisolone, followed by oral prednisone, and oral prednisone alone, which was carried out in acute optic neuritis.53 In the intravenous corticosteroid group visual recovery was accelerated but there was no long term benefit to vision. In the oral ...

Results A total of 173 patients were included in the cohort. Fifty patients (28.9%) were AQP4-Ab-positive and diagnosed with NMOSD-ON. Of 123 patients with seronegative AQP4-Ab, 37 (30.1%) patients had atypical ON, with male predominance (25, 67.6%). The atypical ON group (compared with the typical ON and NMOSD-ON groups) had a significantly lower female:male ratio (1:2.1 vs 1.8:1 and 9:1, respectively, p=0.001 and p,0.001), an older mean age of onset (44.8, 13-71 years vs 36.9, 13-73 years and 36.2, 13-66 years, p=0.003 and p=0.004), a lower rate of good (≥0.5) visual recovery (6.7% vs 79.8% and 30.9%, p,0.001 and p,0.001) and (compared with the NMOSD-ON group) a lower recurrence rate during a 2-year follow-up (29.3% vs 60%, p=0.009). However, none developed to multiple sclerosis or neuromyelitis optica in the atypical ON group. ...

Shortly after this patient presented, Immunex issued a drug warning citing observations of rare cases of demyelinating episodes including optic neuritis and transverse myelitis in patients with rheumatoid arthritis treated with etanercept. At the time of this writing, 20 to 25 cases of CNS demyelination associated with the use of etanercept have been reported to Immunex (Donald Goodkin, unpublished data, 2001).. Optic neuritis developed in this individual after using etanercept for 9 months. Cerebral MRI performed 2 months later revealed new disease activity in the absence of new symptoms. Despite discontinuing etanercept, new enhancing lesions and neurologic symptoms developed, fulfilling the criteria for clinically definite relapsing remitting MS. What role, if any, did the use of etanercept play in the onset of MS in this individual? Three possibilities exist. First, the development of MS and the use of etanercept could have been coincidental. Second, the use of etanercept could have ...

Imagine waking up one morning to discover that your vision is suddenly blurred. Over the next few days it becomes progressively worse until you can no longer make out the numbers on the alarm clock, and the picture on the wall is a jumble of fuzzy, colored patches. After a visit to the ophthalmologist, you learn that you have optic neuritis, an inflammation of the optic nerve. The inflammation gradually subsides over the next several weeks. Your vision improves, but you are left with a partially blind region in the center of your visual field reducing your acuity to 20/80. You would probably be able to read the newspaper with a magnifying glass, to navigate without the aid of a cane, and to recognize familiar faces that are nearby.. ...

... (PDPH) is a complication of puncture of the dura mater (one of the membranes that surround the brain and spinal cord).[1] The headache is severe and described as "searing and spreading like hot metal," involving the back and front of the head, and spreading to the neck and shoulders, sometimes involving neck stiffness. It is exacerbated by movement, and sitting or standing, and relieved to some degree by lying down. Nausea, vomiting, pain in arms and legs, hearing loss, tinnitus, vertigo, dizziness and paraesthesia of the scalp are common.[1] It is a common side-effect of spinal anesthesia and lumbar puncture. Leakage of cerebrospinal fluid puncture causes reduced fluid levels in the brain and spinal cord. Onset occurs within two days in 66 percent and within three days in ninety percent of PDPH cases. It occurs so rarely immediately after puncture that other possible causes should be investigated when it does.[1] Using a pencil point rather than a cutting spinal ...
