However, it may not be the only cause of papilledema. The authors reported an association among coronavirus disease 2019 (COVID-19), bilateral papilledema, blindness, and Wernicke\u2019s encephalopathy (WE).<\/jats:p>\n <\/jats:sec>\n \n OBSERVATIONS<\/jats:title>\n An 18-year-old woman presented to the neurosurgery service with rapid profound vision loss and bilateral papilledema. She had COVID-19 3 months earlier with subsequent loss of smell (anosmia) and taste (ageusia), which resulted in hyperemesis and a 43-lb weight loss. Examination revealed ataxia, horizontal nystagmus, and blindness. Magnetic resonance imaging and magnetic resonance venography of her brain were normal. Presumptive diagnosis of WE was made, and she was treated with intravenous thiamine with restoration of vision within 48 hours. Patient\u2019s thiamine level was less than half the normal value.<\/jats:p>\n <\/jats:sec>\n \n LESSONS<\/jats:title>\n Neurosurgeons should be aware of this unique correlation between papilledema and vision loss and its association with WE due to post\u2013COVID-19 hyperemesis and weight loss from anosmia and ageusia.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/case22332","type":"journal-article","created":{"date-parts":[[2022,9,26]],"date-time":"2022-09-26T10:32:16Z","timestamp":1664188336000},"source":"Crossref","is-referenced-by-count":0,"title":["Bilateral papilledema with vision loss due to post\u2013COVID-19\u2013induced thiamine deficiency: illustrative case"],"prefix":"10.3171","volume":"4","author":[{"given":"Kern H.","family":"Guppy","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, The Kaiser Permanente Medical Group, Sacramento, California"},{"name":"Department of Neurological Surgery, University of California, San Francisco, San Francisco, California; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yekaterina K.","family":"Axelrod","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Kaiser Permanente Medical Group, Sacramento, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Han","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, The Kaiser Permanente Medical Group, Stockton, California"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"1","key":"b1","series-title":"Int Ophthalmol Clin","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1097\/IIO.0b013e3182aabf11","article-title":"Epidemiology and risk factors for idiopathic intracranial hypertension","volume":"54","author":"Chen J","year":"2014","unstructured":"Chen J, Wall M.
