She awoke the next morning with profoundly blurred distance vision. She presented to eye casualty later that morning, approximately 18 hours postingestion: examination demonstrated myopia and bilateral choroidal effusions. Acetazolamide is used to minimise symptoms of altitude sickness. Rarely, its use can be linked with ophthalmic side effects, such as myopia. A handful of case reports also describe choroidal effusions secondary to its use as part of ophthalmic treatment (eg, postoperatively). This is the first reported case in which choroidal effusions have been demonstrated as a side effect of its prophylactic use against altitude sickness.<\/jats:p>","DOI":"10.1136\/bcr-2021-246145","type":"journal-article","created":{"date-parts":[[2022,1,17]],"date-time":"2022-01-17T10:48:00Z","timestamp":1642416480000},"page":"e246145","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Bilateral choroidal effusions after taking acetazolamide for altitude sickness"],"prefix":"10.1136","volume":"15","author":[{"given":"Alice","family":"Rothwell","sequence":"first","affiliation":[{"name":"Ophthalmology, University Hospitals Dorset NHS Foundation Trust, Bournemouth, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Owen","family":"Anderson","sequence":"additional","affiliation":[{"name":"Ophthalmology, University Hospitals Dorset NHS Foundation Trust, Bournemouth, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,1,17]]},"reference":[{"key":"2025082704111117000_15.1.e246145.1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.e6779"},{"key":"2025082704111117000_15.1.e246145.2","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1016\/j.wem.2018.09.002","article-title":"Reduced acetazolamide dosing in Countering altitude illness: a comparison of 62.5 vs 125 Mg (the radical trial)","volume":"30","author":"McIntosh","year":"2019","journal-title":"Wilderness Environ Med"},{"key":"2025082704111117000_15.1.e246145.3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8305.2012.00629.x"},{"key":"2025082704111117000_15.1.e246145.4","doi-asserted-by":"crossref","first-page":"397","DOI":"10.1016\/j.wem.2016.04.002","article-title":"Myopic changes in a Climber after taking acetazolamide and the use of corrective lenses to Temporize symptoms: a case report from Mount Kilimanjaro","volume":"27","author":"Hill","year":"2016","journal-title":"Wilderness Environ Med"},{"key":"2025082704111117000_15.1.e246145.5","unstructured":"Bayer AT , Moroi SE .
