Two Cases of Atypical Optic Neuritis / 대한소아신경학회지

ABSTRACT

Optic neuritis refers to any inflammatory disorder of optic nerves, but it usually denotes an acute or subacute disease of optic nerves attributed to inflammation associated with demyelination. The diagnosis of optic neuritis is usually made on a clinical ground. The condition usually presents as a painful subacute unilateral loss of vision, which progresses over a few days to 2 weeks. The pain varies in severity, although it typically does not interfere with sleep. We report 2 cases of atypical optic neuritis rapidly recovered by the administration of high doses of steroid that presented with severe eyeball pain accompanied by vague visual loss and painlessly insidious onset of visual loss respectively, with normal findings in fundoscopic examinations, visual evoked potentials and orbital MRIs.
