Case report: We report the case of a 76-year-old woman who attended our hospital because of a sudden loss of visual acuity in her left eye. The problem appeared to be that of retrobulbar optic neuritis. However, the age of the patient together with the simultaneous use of Infliximab to treat her rheumatoid arthritis, suggests the demyelination may have been associated with the Infliximab use.
Discussion: TNFa inhibitors (including Infliximab) are associated with demyelinating diseases including optic neuritis.
