  2. Optic neuritis - Wikipedia

    en.wikipedia.org/wiki/Optic_neuritis

    On medical examination the head of the optic nerve can easily be visualized by a slit lamp with a high positive lens or by using direct ophthalmoscopy; however, frequently there is no abnormal appearance of the nerve head in optic neuritis (in cases of retrobulbar optic neuritis), though it may be swollen in some patients (anterior papillitis ...

  3. Anterior ischemic optic neuropathy - Wikipedia

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

    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. In some patients the optic nerve is nearly as large as the opening in the back of the eye, and the optic disc appears "crowded" when seen by ophthalmoscopy. A crowded disc is also referred to as a "disc ...

  4. 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.

  5. Optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Optic_neuropathy

    multiple sclerosis associated optic neuritis (MSON) unclassified optic neuritis (UCON) forms. [4] Medical examination of the optic nerve with an ophthalmoscope may reveal a swollen optic nerve, but the nerve may also appear normal. Presence of an afferent pupillary defect, decreased color vision, and visual field loss (often central) are ...

  6. Chronic relapsing inflammatory optic neuropathy - Wikipedia

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

    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 ...

  7. 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.

  8. Optic disc drusen - Wikipedia

    en.wikipedia.org/wiki/Optic_disc_drusen

    The optic nerve is a cable connection that transmits images from the retina to the brain. It consists of over one million retinal ganglion cell axons. The optic nerve head, or optic disc is the anterior end of the nerve that is in the eye and hence is visible with an ophthalmoscope. It is located nasally and slightly inferior to the macula of ...

  9. Neuromyelitis optica spectrum disorder - Wikipedia

    Additional MRI findings for absent/unknown AQP4-IgG Optic neuritis: Either 1) brain MRI showing normal findings or only nonspecific white matter lesions, or 2) optic nerve MRI showing T2-hyperintensity, or T1 enhancing lesion, greater than 1/2 optic nerve length or involving optic chiasm Acute myelitis
