the spectrum of mitochondrial dna mutations in iranian lebers hereditary optic neuropathy patients
we studied 74 patients with lebers hereditary optic neuropathy (lhon) to investigate causative mtdna mutations (g3460a, g11778a, t14484c, g4459a) in iranian lhon patients. fifty two patients carried the mitochondrial dna (mtdna) g11778a mutation, while one had the t14484c mutation 4 patients had the g3460a mutation and one had the g14459a mutation. our results showed a similarity in the pattern...
متن کاملlack of association between lebers hereditary optic neuropathy primary point mutations and multiple sclerosis in iran
the hypothesis that mitochondrial genes may be implicated in susceptibility to multiple sclerosis (ms) is supported by an increasing number of case reports on lebers hereditary optic neuropathy (lhon)-associated mitochondrial dna (mtdna) point mutations in patients with ms. a number of mtdna mutations with primary pathogenic significance for lhon, a maternally inherited disease causing severe b...
متن کاملPattern visual evoked cortical potentials in patients with toxic optic neuropathy caused by toluene abuse.
PURPOSE Electrophysiological evaluation of the visual function of patients with toxic neuropathy caused by toluene abuse. METHODS Fifteen patients (mean age 25.6 years, eight men and seven women) were diagnosed with bilateral optic neuropathy. Pattern visual evoked cortical potentials (PVECPs) and clinical symptoms were investigated. RESULTS Visual acuities at the initial visit were less th...
متن کاملAutoregressive Modeling of Visual Evoked Potentials and Its Applications to Optic Nerve Diseases-Ischemic Optic Neuropathy and Optic Neuritis
It is important to differentiate the diagnosis of ischemic optic neuropathy (ION) and optic neuritis (ON) for prognostic and therapeutic reasons. In most cases, differentiation is accomplished by assessing the disc appearance, the presence or absence of retrobulbar pain, the age of the patient, the mode of onset and other features of clinical and laboratory evaluation. However, in certain group...
