Background: Multiple sclerosis and other demyelinating processes are sometimes difficult to differentiate from the neurological involvement in autoimmune diseases. Distinguishing multiple sclerosis from other lesions due to autoimmune diseases is crucial to avoid unsuitable or delayed treatments. Methods: Charts of 6 patients diagnosed with mimicking multiple sclerosis between 1996 and 2014 were retrospectively assessed. Results: The mean age at diagnosis was 35±7 years...

Graves' orbitopathy, a condition seen in the autoimmune syndrome Graves' disease, affects the fatty tissue and muscles inside the orbit. Graves' orbitopathy is associated with increasing exophthalmos and sometimes leads to compressive dysthyroid optic neuropathy, resulting in progressive vision loss. Dysthyroid compressive optic neuropathy, functional problems, and cosmetic problems are the main indications for surgical decompression of the orbit, especially if conservative treatment has not led to a reduction in symptoms...

BACKGROUND: We describe a 75-year-old woman who experienced vision loss in her left eye due to biopsy-proven giant cell arteritis (GCA). She subsequently developed pachymeningitis causing refractory headaches and bilateral optic neuropathy and maculopathy. METHODS: Case report with literature review. RESULTS: Eighteen months after the initial diagnosis of GCA, imaging studies in our patient demonstrated pachymeningeal enhancement, and meningeal biopsy confirmed lymphoplasmacytic tissue infiltrates with low frequencies of IgG4+ plasma cells...

A 40 year-old male presented after one year of unilateral, progressive, steroid-responsive, orbital inflammatory disease causing proptosis, extraocular muscle (EOM) restriction, and compressive optic neuropathy. The development of anti-thyroidal antibodies prompted the diagnosis of thyroid eye disease (TED); however, the prolonged active phase, remarkable reversibility of ophthalmic features with high-dose corticosteroids, unilaterally of disease, uncharacteristic EOM involvement (including both obliques), and the absence of autoimmune thyroid disease provoked consideration of alternative diagnoses...

No therapies exist to prevent neuronal deficits in multiple sclerosis (MS), because the molecular mechanism responsible for the progressive neurodegeneration is unknown. We previously showed that axon injury-induced neuronal endoplasmic reticulum (ER) stress plays an important role in retinal ganglion cell (RGC) death and optic nerve degeneration in traumatic and glaucomatous optic neuropathies. Optic neuritis, one of the most common clinical manifestations of MS, is readily modeled by experimental autoimmune encephalomyelitis (EAE) in mouse...

The ability of novel mitochondrial uncoupler prodrug of 2,4-dinitrophenol (DNP), MP201, to prevent neuronal damage and preserve visual function in an experimental autoimmune encephalomyelitis (EAE) model of optic neuritis was evaluated. Optic nerve inflammation, demyelination, and axonal loss are prominent features of optic neuritis, an inflammatory optic neuropathy often associated with the central nervous system demyelinating disease multiple sclerosis. Currently, optic neuritis is frequently treated with high-dose corticosteroids, but treatment fails to prevent permanent neuronal damage and associated vision changes that occur as optic neuritis resolves, thus suggesting that additional therapies are required...

Thyroid associated ophthalmopathy (TAO) is a common complication of Graves' disease (GD). The clinical manifestations are mainly swelling and retracted eyelid, protopsis and limited eye movements, and optic neuropathy can be seen in severe cases. The mechanism of TAO is not yet clear. A large number of studies have found that the disorders of autoimmunity play an important role in TAO, while genetic factors, oxidative stress, and environmental factors such as smoking participate in it. Therefore, we consult a large number of studies and expound the pathogenesis from the aspects of genetic susceptibility, immune mechanism, oxidative stress, and the effects of smoking to provide referrences for clinical associated studies...

Thyroid-associated orbitopathy (TAO) is an inflammatory autoimmune disorder. The most serious complication of TAO is dysthyroid optic neuropathy (DON), which can lead to permanent vision loss because of volume expansion in the orbital apex. Orbital radiation therapy (ORT) is an anti-inflammatory treatment used in the treatment of active TAO. Clinical studies support radiotherapy as having a modest effect on DON, and early radiotherapy may protect against disease progression to DON. Current studies suggest that radiotherapy is generally safe...

Thyroid-associated ophthalmopathy is the most frequent extrathyroidal involvement of Graves' disease but it sometimes occurs in euthyroid or hypothyroid patients. Thyroid-associated ophthalmopathy is an autoimmune disorder, but its pathogenesis is not completely understood. Autoimmunity against putative antigens shared by the thyroid and the orbit plays a role in the pathogenesis of disease. There is an increased volume of extraocular muscles, orbital connective and adipose tissues. Clinical findings of thyroid-associated ophthalmopathy are soft tissue involvement, eyelid retraction, proptosis, compressive optic neuropathy, and restrictive myopathy...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect different ocular structures, such as cornea, conjunctiva, episclera, sclera, uveal tract, retina, optic nerve and vessels. Neuro-ophthalmologic manifestations in SLE include different degrees of involvement of retina, choroid and optic nerve. Retinal changes are one of the most common ocular involvements and are frequently used as clinical criteria for activity, even if isolated. Studies show that up to 29% of patients with active SLE manifest retinal disease...

A 52-year-old woman presented with painless vision loss for 3 months. She was in custody for allegedly robbing a bank and had recently been diagnosed with paranoid schizophrenia. She had 20/100 VA OD, a 2+RAPD, and optic atrophy. Extensive diagnostic workup including MRI, Fluorescein Angiography, Infectious Disease Panel, lumbar puncture, and leptomeningeal biopsy were unrevealing. Vision in her right eye declined to NLP and her left eye declined to 20/200 VA. Anti N-methyl-D-aspartate (NMDA) Autoimmune Encephalitis was diagnosed based on CSF serology and clinical suspicion...

Background: Optic nerve disease can occur from a variety of different causes, with vascular, inflammatory or toxic pathologies. In such cases, it is hardly possible to clarify the aetiology. These diseases of the optic nerve are usually accompanied by progressive loss of visual field and visual impairment. Patient: We report a case of a 74-year-old woman complaining of loss of visual acuity, visual and blurred vision in the left eye in 2010. We made the diagnosis of non-arteritic ischemic optic neuropathy (NAION)...
