Typically, symptoms are very mild, such as a slight decrease in visual acuity or a small scotoma. There is no treatment for this condition, and most cases resolve spontaneously within 12 weeks without any permanent visual changes. Here we present a case of a previously fit and well 29-year-old female who developed atypical symptoms of \u201cblue spots\u201d in both eyes after ascending to 5,420 m. She descended promptly and was assessed in an emergency ophthalmology clinic in the United Kingdom (UK) upon her return. Her visual recovery was prolonged, which, combined with the presenting symptoms, makes this case atypical and assists in broadening understanding of HAR.\n                  <\/jats:p>","DOI":"10.1089\/ham.2024.0139","type":"journal-article","created":{"date-parts":[[2025,2,6]],"date-time":"2025-02-06T05:21:01Z","timestamp":1738819261000},"page":"99-101","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["High-Altitude Retinopathy Presenting as Blue Spots with Prolonged Recovery: A Case Report"],"prefix":"10.1177","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7711-3834","authenticated-orcid":false,"given":"Ben","family":"Smith","sequence":"first","affiliation":[{"name":"Neuroscience and Ophthalmology, Institute of Inflammation and Ageing, University of Birmingham, Birmingham, United Kingdom."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicola","family":"Wetherill","sequence":"additional","affiliation":[{"name":"Plymouth Hospitals NHS Trust, Plymouth, United Kingdom."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel S.","family":"Morris","sequence":"additional","affiliation":[{"name":"Cardiff Eye Unit, University Hospital of Wales, Cardiff, United Kingdom."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,3,3]]},"reference":[{"issue":"2","key":"e_1_3_5_2_1","doi-asserted-by":"crossref","first-page":"11532","DOI":"10.1371\/journal.pone.0011532","article-title":"Delayed appearance of high-altitude retinal hemorrhages","volume":"6","author":"Barthelmes D","year":"2011","unstructured":"Barthelmes D, , Bosch MM, , Merz TM, et al.
