Although idiopathic steroid resistant optic neuritis is very uncommon, there is no established treatment protocol for such patients. Toll like receptors (TLRs) especially TLR-9 has been shown to play a role in the pathogenesis of optic neuritis. This small case series aims to determine whether immunomodulators directed specifically at TLR-9(i.e. TLR-9 antagonism)play any role in improving the visual function in such patients.
