Abstract

PURPOSE: To determine whether clinical features and visual outcomes of myelin oligodendrocyte glycoprotein antibody-associated optic neuritis (MOG-ON) differ between subjects who are White compared with those who are Asian.DESIGN: Multicenter retrospective cohort.METHODS: SETTING: Multicenter.PATIENT: 153 subjects who are White or Asian with history of adult-onset(age=18years-old) optic neuritis and positive MOG-IgG serology by cell-based assay were enrolled from two unpublished cohorts(January 2017-November 2019) and nine published cohorts with case-level data available(2012-2018). Subjects with alternative etiologies of demyelinating disease and positive or lack of AQP-4-IgG serology result were excluded.MAIN OUTCOME MEASURES: Clinical features and final visual outcomes.RESULTS: One hundred and fifty-three subjects who are White(n=80) or Asian(n= 73) were included. 93(61%) were female, mean age of onset was 40.8±14.9 years-old, median follow up was 35.2(range1-432) months, which were all similar between White and Asian subjects. Subjects who are White were more likely to have recurrent optic neuritis(57(71%) vs. 20(27%);p=0.001) and extra-optic nerve manifestations(35(44%) vs. 8(11%);p=0.001). Optic disc swelling, neuroimaging findings, presenting visual acuity, treatment and final visual acuity did not differ according to subjects' race. Despite the high prevalence of severe visual loss(<20/200) during nadir, the majority of subjects had good recovery of visual acuity(>20/40) at final examination(51(66%) of 77 subjects who are White vs. 52(74%) of 70 subjects who are Asian).CONCLUSION: Subjects with MOG-ON who are White were more likely to have recurrent disease and extra-optic nerve manifestations. Visual outcomes were similar between subjects who are White and those who are Asian.
