  2. Optic neuritis - Wikipedia

    en.wikipedia.org/wiki/Optic_neuritis

    The repetition of an idiopathic optic neuritis is considered a distinct clinical condition, and when it shows demyelination, it has been found to be associated to anti-MOG and AQP4-negative neuromyelitis optica. [20] When an inflammatory recurrent optic neuritis is not demyelinating, it is called chronic relapsing inflammatory optic neuropathy ...

    en.wikipedia.org/wiki/Autoimmune_optic_neuropathy

    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.

  4. Optic papillitis - Wikipedia

    en.wikipedia.org/wiki/Optic_papillitis

    Pseudopapilledema is a normal variant of the optic disk, in which the disk appears elevated, with indistinct margins and a normal vascular pattern. Pseudopapilledema sometimes occurs in hyperopic individuals. Workup of the patient with papillitis includes lumbar puncture and cerebrospinal fluid analysis. B. henselae infection can be detected by ...

  5. Optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Optic_neuropathy

    Optic neuritis, when combined with the presence of multiple demyelinating white matter brain lesions on MRI, is suspicious for multiple sclerosis. Several causes and clinical courses are possible for the optic neuritis. It can be classified in: Single isolated optic neuritis (SION) relapsing isolated optic neuritis (RION)

  6. Chronic relapsing inflammatory optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Chronic_relapsing...

    Corticosteroid responsive optic neuritis not associated with demyelinating disease should also be ruled out, including sarcoidosis, systemic lupus erythematosus, or other systemic autoimmune disease. [11] Hereditary causes such as Leber's hereditary optic neuropathy are also part of the differential diagnosis. [12]

  7. Visual pathway lesions - Wikipedia

    en.wikipedia.org/wiki/Visual_pathway_lesions

    Optic neuritis involving internal fibers of the optic nerve causes central scotoma. [ 4 ] lf unilateral central scotoma is detected, careful observation of the temporal visual field of other eye is essential to rule out the possibility of compressive lesions at the junction of optic nerve and optic chiasm.

  8. Ischemic optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Ischemic_optic_neuropathy

    Ischemic optic neuropathy (ION) is the loss of structure and function of a portion of the optic nerve due to obstruction of blood flow to the nerve (i.e. ischemia).Ischemic forms of optic neuropathy are typically classified as either anterior ischemic optic neuropathy or posterior ischemic optic neuropathy according to the part of the optic nerve that is affected.

  9. Anterior ischemic optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Anterior_ischemic_optic...

    The optic disc is where the axons from the retinal ganglion cells collect into the optic nerve. The optic nerve is the bundle of axons that carry the visual signals from the eye to the brain. This optic nerve must penetrate through the wall of the eye, and the hole to accommodate this is usually 20-30% larger than the nerve diameter.
