Optic neuritis typically affects young adults ranging 18–45 years of age, with a mean age of 30–35 years. There is a strong female predominance. The annual incidence is approximately 5/100,000, with a prevalence estimated to be 115/100,000 (0.12%).
It presents with visual loss and signs of optic nerve dysfunction, such as loss of color vision, afferent pupil defect, and sometimes abnormalities of the optic disc. The clinical features of AON can be variable and present in several unilateral or bilateral forms: Acute anterior or retrobulbar optic neuritis sometimes associated with pain.
Optic neuritis* is inflammation of the optic nerves. In dogs this is most commonly caused by granulomatous meningoencephalitis or infection. [74] Persistent pupillary membrane is a condition of the eye involving remnants of a fetal membrane that persist as strands of tissue crossing the pupil. [63] Uveitis* is inflammation within the eye.
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.
Optic neuritis is also commonly associated with periocular pain, phosphenes, and other visual disturbances. Treatment of acute optic neuritis involves corticosteroids, plasmapheresis, and IV immunoglobulins in additions to disease modifying immunotherapies to manage the underlying neuropathology associated with the acute inflammatory episode.

History of optic neuritis with one relapse; Objectively measured visual loss; NMO-IgG seronegative; Contrast enhancement on imaging of acutely inflamed optic nerves; Response to immunosuppressive treatment and relapse on withdrawal or dose reduction. CRION has been included as a subtype in a 2022 international consensus classification of optic ...
Lesions involving the whole optic nerve cause complete blindness on the affected side, that means damage at the right optic nerve causes complete loss of vision in the right eye. [3] Optic neuritis involving external fibers of the optic nerve causes tunnel vision. [4] Optic neuritis involving internal fibers of the optic nerve causes central ...
Treatment of toxic and nutritional optic neuropathy is dictated by the cause of the disorder. Toxic optic neuropathy is treated by identification and removal of the offending agent. Depending upon the individual affected, the nature of the agent, total exposure prior to removal, and degree of vision loss at the time of diagnosis, the prognosis ...
