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.
Optic neuritis describes any ... or ischemic optic neuropathy due to thrombosis or embolism of the vessel that supplies the optic nerve. [13] [14] Up to 50% of ...
Up to 50% of patients with MS will develop an episode of optic neuritis and 20% of the time optic neuritis is the presenting sign of MS. The presence of demyelinating white matter lesions on brain MRIs at the time of presentation for optic neuritis is the strongest predictor in developing clinical diagnosis of MS. Almost half of patients with ...
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 ...
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: intramedullary lesion > 3 contiguous segments, or spinal atrophy ≥ 3 contiguous segments
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)
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 ...
NAION is the most frequently diagnosed sudden optic nerve disease in adults over 50, predominantly affecting Caucasians, [27] with variable rates reported in Asian populations, [28] [29] and affecting males more than females. [30] Presentation can vary, but patients typically report painless visual loss upon waking up in the morning or after a ...
