Thus, little is known about the incidence, optimal management, and outcomes of this particular type of compressive optic neuropathy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>The authors present the case of a 52-year-old female with progressive monocular vision loss. After an extensive workup, including a formal neuro-ophthalmology assessment, her symptoms were attributed to a neurovascular conflict between the optic nerve and a nonectatic supraclinoid ICA. She underwent a pterional craniotomy for optic nerve decompression, including bony unroofing of the optic canal and fenestration of the dural sheath. On follow-up, there was improvement in both her radiographic and clinical findings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>This case highlights a unique indication for optic nerve decompression in the setting of monocular vision loss caused by nonectatic vascular compression.<\/jats:p>\n                    <jats:p>\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/thejns.org\/doi\/10.3171\/CASE24623\">https:\/\/thejns.org\/doi\/10.3171\/CASE24623<\/jats:ext-link>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case24623","type":"journal-article","created":{"date-parts":[[2025,3,31]],"date-time":"2025-03-31T06:27:44Z","timestamp":1743402464000},"source":"Crossref","is-referenced-by-count":1,"title":["Compressive optic neuropathy caused by a nonectatic internal carotid artery: illustrative case"],"prefix":"10.3171","volume":"9","author":[{"given":"Jennifer R.","family":"Lischynski","sequence":"first","affiliation":[{"name":"Section of Neurosurgery, Department of Surgery, University of Manitoba, Winnipeg, Manitoba, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-0755-9914","authenticated-orcid":true,"given":"Samuel","family":"Molot-Toker","sequence":"additional","affiliation":[{"name":"Section of Neurosurgery, Department of Surgery, University of Manitoba, Winnipeg, Manitoba, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Behzad","family":"Mansouri","sequence":"additional","affiliation":[{"name":"Brain, Vision, and Concussion Clinic, Winnipeg, Manitoba, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony M.","family":"Kaufmann","sequence":"additional","affiliation":[{"name":"Section of Neurosurgery, Department of Surgery, University of Manitoba, Winnipeg, Manitoba, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"5","key":"bib1","series-title":"Am J Ophthalmol","first-page":"677","article-title":"Optic nerve contact and compression by the carotid artery in asymptomatic patients","volume":"123","author":"Jacobson","year":"1997","unstructured":"Jacobson DMWarner JJBroste SK.Optic nerve contact and compression by the carotid artery in asymptomatic patients.
