We report a case of myelin oligodendrocyte glycoprotein (MOG) related optic neuritis in a SARS\u2010CoV\u20102 (COVID\u201019) patient.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Case report.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A 36\u2010year\u2010old Malay gentleman with underlying hypertension presented with the first episode of bilateral progressively worsening blurred vision for 1 week associated with retrobulbar pain. There were no other neurological symptoms. He had fever a week before the eye symptoms and tested positive for COVID\u201019. He received COVID\u201019 booster vaccine a month before the disease onset. On examination, his vision was hand motion on right eye and 6\/18 on left eye. Relative afferent pupillary defect (RAPD) was positive on right eye with abnormal optic nerve function tests. Anterior segments were unremarkable. Fundus examination showed bilateral optic disc swelling. MRI revealed multifocal hyperintense subcortical white matter lesions. Optic nerves appeared normal with no enhancement seen. Blood investigation showed a positive serum MOG antibody. Intravenous methylprednisolone was commenced followed by oral prednisolone after which his vision and ocular symptoms markedly improved. The oral prednisolone was tapered alongside addition of azathioprine. At 1 month, the disease was stable with no recurrence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>While optic neuritis has been associated with both COVID\u201019 infection and vaccination, MOG IgG antibody\u2010mediated optic neuritis is also a possible manifestation. This type of optic neuritis associated with COVID\u201019 infection does not show a similar pattern of frequent recurrences as seen in non\u2010COVID\u201019 related optic neuritis.<\/jats:p><\/jats:sec>","DOI":"10.1002\/iid3.1051","type":"journal-article","created":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T13:46:45Z","timestamp":1698241605000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Myelin oligodendrocyte glycoprotein antibody\u2010associated optic neuritis in a post\u2010COVID\u201019 infection patient"],"prefix":"10.1002","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9465-2944","authenticated-orcid":false,"given":"Mohamad Azlan","family":"Zaini","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine Universiti Kebangsaan Malaysia  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayesha","family":"Mohd Zain","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine Universiti Kebangsaan Malaysia  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5137-1632","authenticated-orcid":false,"given":"Norshamsiah","family":"Md Din","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine Universiti Kebangsaan Malaysia  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9259-5846","authenticated-orcid":false,"given":"Chenshen","family":"Lam","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine Universiti Kebangsaan Malaysia  Kuala Lumpur Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,10,25]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.9540"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12026-014-8534-z"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmir.2020.03.004"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2018.07.020"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1471-4159.1999.0720001.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41582-018-0112-x"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-018-9122-2"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000009619"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/WNO.0000000000001049"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/s41983-022-00496-4"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.2147\/IMCRJ.S315103"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000025865"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/ncn3.12595"},{"key":"e_1_2_6_15_1","volume-title":"Myelin\u00a0Oligodendrocyte Glycoprotein\u00a0(MOG)\u00a0Optic Neuritis:\u00a0A\u00a0Case Series","author":"Nurul\u2010Ain M","year":"2021"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1093\/qjmed\/hcac208"}],"container-title":["Immunity, Inflammation and Disease"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/iid3.1051","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T08:06:17Z","timestamp":1698912377000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/iid3.1051"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,10]]},"references-count":15,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2023,10]]}},"alternative-id":["10.1002\/iid3.1051"],"URL":"https:\/\/doi.org\/10.1002\/iid3.1051","archive":["Portico"],"relation":{},"ISSN":["2050-4527","2050-4527"],"issn-type":[{"value":"2050-4527","type":"print"},{"value":"2050-4527","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,10]]},"assertion":[{"value":"2023-06-16","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-09-04","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-10-25","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e1051"}}
