In addition, early diagnosis and timely medical care are essential to reduce the risk of morbidity and mortality, yet it remains a challenging procedure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case Report<\/jats:title><jats:p>A 35-year-old man working in a fireworks factory came to our emergency department with acute mental change and progressive disturbance of consciousness. The patient's vital signs were stable, and he presented with enlargement of both pupils with a weak reaction to light. Head computed tomography showed low signal intensities in the bilateral basal ganglia. He was admitted to the neurologic intensive care unit, where additional laboratory workup showed high anion-gap metabolic acidosis. Methanol poisoning was thus considered. Before being treated with sodium bicarbonate infusion, hemodialysis, folate, and high-dose vitamin B, the blood and urine samples were collected for toxicity tests, which turned out to be methanol poisoning. After 8 hours of hemodialysis, the patient's consciousness recovered, but he complained of a complete loss of vision in both eyes. Brain and optic nerve magnetic resonance images showed bilateral symmetric putamen lesions and optic neuropathy. Ophthalmic tests indicated visual pathway impairment and optic disc swelling but no fluorescein leakage. The right eye's vision was partially restored on the third day, but he could only count fingers at 20 cm. Unfortunately, his eyesight ceased to improve during the 6 months of follow-up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Early diagnosis and prompt treatment will improve the prognosis of methanol poisoning in terms of vision and patient survival. Awareness and supervision of commercial alcohol use are indispensable for similar industrial processes.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fmed.2022.918812","type":"journal-article","created":{"date-parts":[[2022,6,14]],"date-time":"2022-06-14T06:25:42Z","timestamp":1655187942000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Case Report: Early Recognition, Treatment, and Occupational Safety Protection are Crucial for Methanol Toxicity"],"prefix":"10.3389","volume":"9","author":[{"given":"Xiaomei","family":"Wu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meifeng","family":"Gu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hainan","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenchu","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,6,14]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1919","DOI":"10.1016\/S0196-0644(05)80424-X","article-title":"Methanol inhalation toxicity","volume":"22","author":"Frenia","year":"1993","journal-title":"Ann Emerg Med."},{"key":"B2","doi-asserted-by":"publisher","first-page":"431","DOI":"10.1097\/00005792-195312000-00002","article-title":"Acute methyl alcohol poisoning: a review based on experiences in an outbreak of 323 cases","volume":"32","author":"Bennett IL","year":"1953","journal-title":"Medicine."},{"key":"B3","doi-asserted-by":"publisher","first-page":"395","DOI":"10.1111\/sdi.12237","article-title":"Trends in toxic alcohol exposures in the United States from 2000 to 2013: a focus on the use of antidotes and extracorporeal treatments","volume":"27","author":"Ghannoum","year":"2014","journal-title":"Semin Dial."},{"key":"B4","doi-asserted-by":"publisher","first-page":"415","DOI":"10.1081\/CLT-120006745","article-title":"American academy of clinical toxicology ad hoc committee on the treatment guidelines for methanol P.
