The post-operative MRI did not demonstrate any ischaemia. The index presentation was worsening recurrent falls and cognitive decline from a large mass in the pineal recess resulting in triventriculomegaly, managed successfully with an endoscopic third ventriculostomy 7 months prior. The enlarging mass was resected via a parieto-occipital interhemispheric approach with a 7\u2009hour operative time and no complications. Immediately post-operatively, she experienced cortical blindness lasting 3\u2009days, improving over 3\u2009weeks to then normal visual function by 8\u2009months. This raises awareness of intraoperative occipital lobe retraction increasing the risk of transient cortical blindness post-operatively, along with the known risk factors of increased age and tentorial angles. Future research with functional MRI is required to further investigate cases of post-operative cortical blindness.<\/jats:p>","DOI":"10.1136\/bcr-2025-264865","type":"journal-article","created":{"date-parts":[[2025,6,27]],"date-time":"2025-06-27T14:35:28Z","timestamp":1751034928000},"page":"e264865","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Transient cortical blindness following occipital lobe retraction in a pineal region meningioma resection"],"prefix":"10.1136","volume":"18","author":[{"given":"Nicholas Zhe Wei","family":"Yip","sequence":"first","affiliation":[{"name":"Medical School, University of Edinburgh Division of Medical and Radiological Sciences, Edinburgh, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4869-768X","authenticated-orcid":false,"given":"Catriona","family":"Barbour-Hastie","sequence":"additional","affiliation":[{"name":"Ophthalmology, NHS Fife, Dunfermilne, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Barron","sequence":"additional","affiliation":[{"name":"Department of Clinical Neurosciences, NHS Lothian, Edinburgh, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justin B","family":"McKee","sequence":"additional","affiliation":[{"name":"Princess Alexandra Eye Pavilion, Edinburgh, UK"},{"name":"Department of Clinical Neurosciences, Royal Infirmary of Edinburgh, Edinburgh, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chandrasekaran","family":"Kaliaperumal","sequence":"additional","affiliation":[{"name":"Department of Clinical Neurosciences, NHS Lothian, Edinburgh, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,6,27]]},"reference":[{"key":"2025082723075260000_18.6.e264865.1","unstructured":"Sarkar S , Tripathy K .
