In LHON there is often a family history of men with the disease and vision loss that is progressive and involves both eyes within weeks to months. The vision loss is commonly unilateral and can vary from very mild to severe, including no light perception. The study found that the IV methylprednisolone group had a faster visual recovery but did not have improved visual acuity compared to the other groups.

Women are three times more likely than men to develop this disease.

Leber hereditary optic neuropathy LHON is the most common which may mimic demyelinating optic neuritis. Long-term management to blastomicoiss recurrence in these patients has been studied and suggests that immunomodulatory agents like beta-interferon delay the diagnosis of clinically definite MS in patients with blstomicosis neuritis and white matter lesions on MRI.

As vision recovers there is reduced inflammation and remyelination begins to occur; although it is often incomplete 5. The only predictor of visual recovery at 6 months was the severity of vision loss at the first recorded visit.

Continuum Minneap Minn ; 20 4 Neuro-ophthalmology: Optic neuritis remains a clinical diagnosis, although imaging with MRI and other modalities can be helpful, especially in atypical cases 2. MRI of the brain, orbit, and neck can also help stratify the risk of developing MS.

An important and unexpected finding of the study was that the IV methylprednisolone group had a reduced risk of a secondary demyelinating event of any kind for the first 2 years after treatment compared to the other two treatment groups; however, this protective effect was lost by year 3 and at all subsequent time points.

Autoimmune optic neuropathy Isolated autoimmune optic neuropathy is different than the typical MS variant in that is less likely to have pain as a distinguishing feature, blastomciosis often to have bilateral vision loss, and more likely to cause progressively worsening vision loss. This case evidences the importance of considering blastomycosis in the differential diagnosis of granulomatous conjunctivitis and when examining an eyelid lesion that resembles a squamous cell carcinoma or atypical papilloma.
