MRI revealed extensive sinus disease, though without direct optic nerve compression; CT scan identified a fungal ball extending into the right clinoid process, with bony erosion and involvement of the deep pneumatised optico-carotid recess. The patient underwent emergency endoscopic sinus surgery, where mucopus, polyps and fungal debris consistent with an infected fungal ball were found in the right nasal cavity and sphenoid sinus. Residual fungal material remained in the deep optico-carotid recess post-washout due to difficult access and dehiscent bony coverings of the optic nerve and carotid. Postoperatively, he was treated with voriconazole and intravenous co-amoxiclav. His vision returned to baseline 3\u2009days postoperative and 3\u2009months later, a second-look surgery confirmed no residual fungal material. Now fully recovered and discharged from follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2025-267664","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T13:20:31Z","timestamp":1785158431000},"page":"e267664","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Loss of vision secondary to a sphenoid fungal ball with full post-surgical recovery"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4383-3040","authenticated-orcid":false,"given":"Anna","family":"Onderkov\u00e1","sequence":"first","affiliation":[{"name":"ENT, Imperial College Healthcare NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1113-0575","authenticated-orcid":false,"given":"Marlene Maria","family":"Speth","sequence":"additional","affiliation":[{"name":"ENT, Imperial College Healthcare NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiago","family":"Soares","sequence":"additional","affiliation":[{"name":"ENT, Imperial College Healthcare NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Rennie","sequence":"additional","affiliation":[{"name":"ENT, Imperial College Healthcare NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,7,27]]},"reference":[{"key":"2026072706201647000_19.7.e267664.1","doi-asserted-by":"publisher","DOI":"10.21053\/ceo.2015.01571"},{"key":"2026072706201647000_19.7.e267664.2","doi-asserted-by":"crossref","DOI":"10.1017\/S0022215109004241","article-title":"Isolated sphenoid fungal sinusitis and vision loss: the case for early intervention","volume":"123","author":"Hu","year":"2009","journal-title":"J Laryngol Otol"},{"key":"2026072706201647000_19.7.e267664.3","doi-asserted-by":"crossref","first-page":"8649","DOI":"10.1038\/s41598-024-59107-2","article-title":"Visual function loss in fungal sphenoid sinusitis: clinical characteristics and outcomes","volume":"14","author":"Chen","year":"2024","journal-title":"Sci Rep"},{"key":"2026072706201647000_19.7.e267664.4","doi-asserted-by":"crossref","first-page":"e123","DOI":"10.1016\/j.jemermed.2011.06.122","article-title":"Acute sphenoid sinusitis induced blindness: a case report","volume":"43","author":"Reynolds","year":"2012","journal-title":"J Emerg Med"},{"key":"2026072706201647000_19.7.e267664.5","doi-asserted-by":"crossref","DOI":"10.1016\/j.idcr.2022.e01440","article-title":"Time equals sight: Sphenoid sinus aspergilloma with vision loss","volume":"27","author":"Ali","year":"2022","journal-title":"IDCases"},{"key":"2026072706201647000_19.7.e267664.6","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199707243370407"},{"key":"2026072706201647000_19.7.e267664.7","doi-asserted-by":"crossref","first-page":"565","DOI":"10.1007\/s42452-020-2323-1","article-title":"Fungal bio-aerosol in multiple micro-environments from eastern India: source, distribution, and health hazards","volume":"2","author":"Karmakar","year":"2020","journal-title":"SN Appl Sci"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2025-267664","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T13:20:32Z","timestamp":1785158432000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2025-267664"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7]]},"references-count":7,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2026,7,27]]},"published-print":{"date-parts":[[2026,7]]}},"alternative-id":["10.1136\/bcr-2025-267664"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2025-267664","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7]]}}}
