Shaktisar Hereditary optic neuropathy This broad category includes many different inherited disorders. Other tests such as visual evoked potentials, electroretinography, and optical coherence tomography can help distinguish between optic nerve and macular abnormalities5. These patients typically experience bilateral vision loss that is more severe, recurrent, and less likely to recover compared to typical optic neuritis. Also, the study concluded that oral prednisone in the standard dosage used in the study was not a viable treatment option 4, Additionally, these patients will have CSF negative for oligoclonal bands. MRI of the brain, orbit, and neck can also help stratify the risk of developing MS.
