ANA, indicative of autoimmune optic neuropathy, is also generally negative. [3] CSF can also be evaluated for oligoclonal bands typical of multiple sclerosis, which will not be present in CRION. [1] A chest X-ray or CT scan should be ordered if granulomatous optic neuropathy caused by sarcoidosis is suspected. [3]
Recurrent demyelinating neuropathy is proposed as a pathophysiological pathway because similar MRI findings have been observed in both RPON and chronic inflammatory demyelinating neuropathy. [ 13 ] [ 22 ] Inflammatory demyelination of the ocular cranial nerves would likely lead to the release of neuropeptides, such as calcitonin gene-related ...
The poor recovery of vision in AON despite anti-inflammatory treatment suggests that ischemia from the underlying vasculitis is an important component, but the details have not been established. It may be reasonable to consider that AON pathogenesis represents an incomplete expression of the SLE-associated optic neuropathy disease process.
The most common cause is multiple sclerosis (MS) or ischemic optic neuropathy due to thrombosis or embolism of the vessel that supplies the optic nerve. [13] [14] Up to 50% of patients with MS will develop an episode of optic neuritis, and 20–30% of the time optic neuritis is the presenting sign of MS.
Radiation optic neuropathy (RON) is also thought to be due to ischemia of the optic nerve that occurs 3 months to 8 or more years after radiation therapy to the brain and orbit. It occurs most often around 1.5 years after treatment and results in irreversible and severe vision loss, which may also be associated with damage to the retina ...
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 ...

There are several causes of toxic optic neuropathy. [1] Among these are: ingestion of methanol (wood alcohol), ethylene glycol (automotive antifreeze), disulfiram (used to treat chronic alcoholism), halogenated hydroquinolones (amebicidal medications), ethambutol and isoniazid (tuberculosis treatment), and antibiotics such as linezolid and chloramphenicol as well as chloroquine and the related ...
