1/113. A multiple sclerosis-like illness in a man harboring the mtDNA 14484 mutation.In most cases of Leber's hereditary optic neuropathy (LHON) the only clinical manifestation is visual loss. A multiple sclerosis-like illness has been infrequently reported in association with LHON. Most patients are women harboring the mtDNA 11778 mutation. We present a young man with clinical and paraclinical evidence of a demyelinating process with profound bilateral visual loss who harbored the mtDNA 14484 mutation associated with LHON.- - - - - - - - - - ranking = 1keywords = optic (Clic here for more details about this article) |
2/113. Acquired convergence-evoked pendular nystagmus in multiple sclerosis.Nystagmus seen only with convergence is unusual. We describe four cases of acquired convergence-evoked pendular nystagmus in patients with multiple sclerosis. The nystagmus was horizontal and asymmetric in all patients. eye movement recordings in one subject showed a conjugate rather than a convergent-divergent relationship of the phase of movement between the two eyes. All patients had evidence of optic neuropathy and cerebellar dysfunction. Occlusion of either eye during fixation of near targets led to divergent drift of the covered eye and a decrease in nystagmus. Intravenous scopolamine reduced nystagmus in one patient. Base-in prisms alleviated symptoms of oscillopsia at near and improving reading visual acuity. Convergence-evoked pendular nystagmus may be more common than currently appreciated, particularly among patients with multiple sclerosis.- - - - - - - - - - ranking = 1keywords = optic (Clic here for more details about this article) |
3/113. Optic-spinal form of multiple sclerosis and anti-thyroid autoantibodies.The optic-spinal form of multiple sclerosis (OSMS), characterized by recurrent involvement of optic nerve and spinal cord with rare brain magnetic resonance imaging lesions, is relatively common among Asians. While individual cases of OSMS with anti-thyroid autoantibodies (ATABs) have been reported, the frequency of ATAbs in OSMS and classical multiple sclerosis has not been studied. We studied serum ATAbs and anti-nuclear antibodies (ANA) in 46 Japanese patients with multiple sclerosis: 14 with OSMS, and 32 with non-OSMS. Six patients were positive for ATAbs: five women with OSMS and one man with non-OSMS. The frequency of ATAbs in OSMS (5/14) was significantly higher than that in non-OSMS (1/32; P = 0.007), but the frequency of ANA did not differ between OSMS (3/14) and non-OSMS (6/32; P = 0.99). There may be a pathogenetic link between anti-thyroid autoimmunity and a subgroup of OSMS in Japanese.- - - - - - - - - - ranking = 2keywords = optic (Clic here for more details about this article) |
4/113. syringomyelia and complex regional pain syndrome as complications of multiple sclerosis.OBJECTIVE: To describe a patient from Southeast asia with the optic-spinal phenotype of multiple sclerosis who developed syringomyelia and resultant complex regional pain syndrome (formerly named reflex sympathetic dystrophy). DESIGN: Case report. SETTING: Department of neurology at a tertiary care hospital in the Republic of singapore. PATIENT: A 53-year-old Chinese woman with a history of optic neuritis developed an episode of left hemiparesis leading to a diagnosis of multiple sclerosis. Serial neuroimaging studies revealed an active demyelinating plaque in the cervical area that later progressed into a syrinx. Over a period of 1 year she also developed signs of sympathetic dysfunction including horner syndrome of the left eye and complex regional pain syndrome in the left hand. CONCLUSIONS: A case of the optic-spinal phenotype of multiple sclerosis that is commonly observed in Southeast asia is described. This characteristically tissue-destructive form of multiple sclerosis resulted in syringomyelia complicated by a complex regional pain syndrome. Possible pathogenic mechanisms for these associations are discussed.- - - - - - - - - - ranking = 370.09071256329keywords = optic neuritis, neuritis, optic (Clic here for more details about this article) |
5/113. multiple sclerosis with extensive lesions left hemiplegia, mental dysfunction and retrobulbar neuritis.multiple sclerosis (MS) is usually diagnosed on the basis of the typical clinical course, with remission and exacerbation in multiple parts of the central nervous system (CNS). Recently, magnetic resonance imaging (MRI) has made a large contribution to the diagnosis of patients with MS. But it is difficult to make a definite diagnosis due to clinical variability of the disease and variable MRI findings. We report the case of a 26-year-old woman who developed progressive left hemiplegia, mental dysfunction, and had extensive bilateral cerebral white matter lesions diagnosed by brain MRI. Complete recovery from the left hemiplegia followed the use of corticosteroid, and her brain MRI findings also improved after medication. Early in the clinical course it was difficult to differentiate between multiple sclerosis and granulomatous angiitis of the CNS. After recovery from the first episode of left hemiplegia and mental dysfunction, she developed acute visual disturbance five months after her first admission. Readmission followed and her retrobulbar neuritis was successfully treated by methylpredonisolone pulse therapy. In summary, she experienced two episodes of neurological deficit, had left hemiplegia and mental dysfunction associated with multiple lesions in bilateral cerebral white matter in brain MRI, and the left retrobulbar neuritis with delay of P100 by visual evoked potential study. Due to these two episodes we concluded that she had multiple sclerosis. Though the initial diagnosis was difficult, prompt treatment and close follow-up was important, since multiple sclerosis and granulomatous angiitis of the CNS can both recur.- - - - - - - - - - ranking = 850.59193033316keywords = neuritis, retrobulbar (Clic here for more details about this article) |
6/113. Postpartum optic neuritis: etiologic and pathophysiologic considerations.The clinical course of four patients with visual loss in the postpartum period due to acute optic neuritis is described. Factors that disclosed the underlying etiology and expression of disease are discussed. The clinical records of four women examined and managed for visual loss after uncomplicated pregnancies and term deliveries were reviewed. Neurodiagnostic examination, treatment modalities, and outcomes were assessed. These four women with varied and confounding medical histories, all with optic neuropathy, eventually were demonstrated to harbor demyelinating disease. Although visual loss in the postpartum period evokes differential diagnostic considerations, the authors' experience suggests that puerperal immune-mediated changes are responsible for activation of optic neuritis associated with relapsing multiple sclerosis.- - - - - - - - - - ranking = 2209.5442753798keywords = optic neuritis, neuritis, optic (Clic here for more details about this article) |
7/113. New therapeutic perspectives for demyelinating retrobulbar optic neuritis.In patients with demyelinating retrobulbar optic neuritis (RON), a spontaneous or corticosteroid-induced improvement is generally observed within the first month, but this is clinically insignificant in 5%-7% of patients. We report the case histories of four patients who were considered to be "non-responders" to corticosteroids because their visus remained unchanged or had improved by only 1/10 after one month from intravenous corticoid therapy begun 2-7 days after disease onset, and who were therefore subsequently administered high intravenous doses of immunoglobulin. Three of these patients completely recovered in a period of 3-9 months; the fourth showed only a partial improvement, but this was consolidated after long-term continuation of the same therapy. These cases suggest the possible efficacy of early administration of intravenous immunoglobulin in RON patients who fail to respond to cortisone therapy. As recently demonstrated in animal models, it can be hypothesised that the result is due to immuno-mediated mechanisms of action that reduce autoimmune responses in the short- and medium-term, and in the long-term favour remyelination.- - - - - - - - - - ranking = 1849.8245664321keywords = optic neuritis, neuritis, retrobulbar, optic (Clic here for more details about this article) |
8/113. optic neuritis in children.PURPOSE: To describe the clinical characteristics of optic neuritis in children, including final visual acuity and development of multiple sclerosis (MS). methods: charts were reviewed of all patients < 15 years of age who presented with optic neuritis to the Bascom Palmer eye Institute or the Miami Children's Hospital between 1986 and 1998. RESULTS: Fifteen patients were identified. There was a slight female predilection in the study group (60%), with a mean age of 9.8 years at presentation. A preceding febrile illness within 2 weeks of visual symptoms was reported in 66% of patients. Initial visual acuity ranged from 20/15 to no light perception. Involvement was bilateral in 66% of patients, and disc swelling was present in 64% of involved eyes. Of the patients who underwent magnetic resonance imaging, 33% had focal demyelinating lesions in the brain, and 63% of affected nerves were enlarged or enhanced with gadolinium. Eleven patients were treated with intravenous steroids. Final visual acuity was > or = 20/40 in 58.3% of eyes. Thirty percent of the patients had vision of finger counting or worse. Four (26%) patients developed MS. The mean age of patients with MS was 12 years, compared with 9 years in children who did not develop MS. patients with unilateral involvement had an excellent visual prognosis (100% > 20/40), but a higher rate of development of MS (75%). Two patients had positive serology for lyme disease. CONCLUSIONS: optic neuritis presents differently in children than in adults. Children typically have bilateral involvement with papillitis following an antecedent viral illness. Although visual prognosis is poorer in children than adults, the development of MS is less common in children. Children who present with unilateral involvement have a better visual prognosis; however, they also develop MS at a greater frequency than children with bilateral involvement. patients who developed MS were, on average, older at presentation with optic neuritis than those who did not develop MS.- - - - - - - - - - ranking = 1803.7277426852keywords = optic neuritis, neuritis, optic (Clic here for more details about this article) |
9/113. Acute asymmetric upper nasal quandrantanopsia caused by a chiasmal colloid cyst in a patient with multiple sclerosis and bilateral retrobulbar neuritis.PURPOSE: To report a patient with multiple sclerosis and a history of sequential bilateral retrobulbar neuritis, who developed new onset of highly asymmetric upper quadrantanopsia. DESIGN: Interventional case report. METHOD: A 36-year-old woman with multiple sclerosis and bilateral retrobulbar neuritis developed an acute asymmetric upper nasal quadrantanopsia. RESULTS: magnetic resonance imaging of the brain revealed a cyst that caused chiasmal compression and bilateral visual field defects. CONCLUSION: New onset of bilateral visual field defects in a patient with diagnosed multiple sclerosis is likely to be caused by a new attack of the demyelinating disease. In this case, a newly diagnosed chiasmal colloid cyst was the cause of visual field defects.- - - - - - - - - - ranking = 850.59193033316keywords = neuritis, retrobulbar (Clic here for more details about this article) |
10/113. Abnormal brain scans in multiple sclerosis.A 25 year old man, with a family history of multiple sclerosis in two preceding generations, developed transient sensory changes and incoordination, initially on the left side, and then several months later on the right side in association with an elevated CSF gamma globulin. This was followed by an acute optic neuritis. During the latter episode he developed a positive brain scan which was unaccompanied by any clinical findings explained by a lesion in that area. Cerebral arteriography was normal and the brain scan returned to normal four weeks later, possibly as a result of blood brain barrier restoration. Abnormal brain scans appear to occur only during acute exacerbations of demyelinating disease, and multiple sclerosis should be part of the differential diagnosis of a positive brain scan in a person in the appropriate age range.- - - - - - - - - - ranking = 368.09071256329keywords = optic neuritis, neuritis, optic (Clic here for more details about this article) |
