Major symptoms are sudden loss of vision (partial or complete), sudden blurred or "foggy" vision, and; pain on movement of the affected eye. [4] [5] [2]Many patients with optic neuritis may lose some of their color vision in the affected eye (especially red), with colors appearing subtly washed out compared to the other eye.
Symptoms of optic neuritis in the affected eye include pain on eye movement, sudden loss of vision, and decrease in color vision (especially reds). Optic neuritis, when combined with the presence of multiple demyelinating white matter brain lesions on MRI, is suspicious for multiple sclerosis .
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.
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 ...
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.
Concurrently, magnetic resonance imaging (MRI) of the optic nerves plays a pivotal role in distinguishing NAION from optic neuritis, a condition with similar symptoms. Notably, MRI revealed optic nerve abnormalities in only a small fraction (15.6%) of NAION patients, compared to almost all (96.9%) patients with optic neuritis. Additionally ...
Toxic and nutritional optic neuropathy is a group of medical disorders defined by visual impairment due to optic nerve damage secondary to a toxic substance and/or nutritional deficiency. The causes of these disorders are various, but they are linked by shared signs and symptoms.
The anterior optic nerve receives blood primarily from the posterior ciliary arteries. The anterior optic nerve, a.k.a. the optic nerve head, is surrounded by the scleral canal, and is vulnerable to crowding of nerve fibers. The portion of the optic nerve head that is visible by looking into the eye with an ophthalmoscope is called the optic disc.
