Optic neuritis describes any condition that causes inflammation of the optic nerve; it may be associated with demyelinating diseases, or infectious or inflammatory ...
Multiple sclerosis and Neuromyelitis optica are autoimmune diseases which both frequently present with optic neuritis, an inflammatory demyelinating neuropathy of the optic nerve. [3] Multiple sclerosis is a disease of unknown etiology which is characterized by neurological lesions "disseminated in time and space". [24]
It occurs primarily in dogs and horses, but can also affect humans. In dogs it affects the gastrointestinal system and lymph nodes, and rarely the skin. [24] Mucormycosis is a collection of fungal and mold diseases in dogs including pythiosis, zygomycosis, and lagenidiosis that affect the gastrointestinal tract and skin. [6]
None directly from optic neuropathy, but complications from underlying causes (e.g., stroke) can be fatal Optic neuropathy is damage to the optic nerve from any cause. The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Magnetic resonance imaging can capture optic nerve inflammation, but this finding is not present in all patients, [1] [3] [13] Diffusion tensor imaging has been shown to detect widespread white matter abnormalities in CRION patients with normal MRI findings. [14] Five diagnostic criteria had been proposed in 2014: [3] History of optic neuritis ...
The second most common initial manifestation of the disease is inflammation of the optic nerve and/or optic chiasm (optic neuritis, ON). [4] ON may lead to varying degrees of visual impairment with decreased visual acuity , although visual field defects, or loss of color vision , may occur in isolation or prior to formal loss of visual acuity.
Retrobulbar neuritis, an inflamed optic nerve, but with a normal-appearing nerve head, is associated with pain and the other findings of papillitis. Pseudopapilledema is a normal variant of the optic disk , in which the disk appears elevated, with indistinct margins and a normal vascular pattern.
