Ophthalmic and neurologic examinations were performed, raising suspicion of post\u2010retinal blindness. Standing contrast computed tomography (CT) of the head revealed a partially calcified, soft tissue attenuating mass in the sphenopalatine sinus with concurrent compression of the optic nerves and chiasm. Differential diagnosis included neoplasia and granulomatous disease. The horse was euthanized, and the head was subsequently examined by magnetic resonance imaging (MRI) followed by gross and histopathology. MRI showed compression of the optic nerves and chiasm. Histopathology revealed the formation of fibrous granulation tissue, osseous metaplasia, and pyogranulomatous inflammation in the sphenopalatine sinus. Periodic acid\u2010Schiff reaction and Grocott silver staining demonstrated branching septated filament hyphae and fungal spores. The optic nerves and chiasm were evident of mild neuronal atrophy, showing mild gliosis, vacuolation, and mild lympho\u2010plasmacytic inflammation. Mycotic sphenopalatine sinusitis should be considered as a more specific diagnosis for post\u2010retinal blindness in horses due to the compression of the optic nerve(s) and chiasm.<\/jats:p>","DOI":"10.1111\/vop.70003","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T13:11:23Z","timestamp":1741698683000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mycotic Sphenopalatine Sinusitis With Concurrent Compression of the Optic Nerves and Chiasm and Severe Visual Impairment in A Horse"],"prefix":"10.1111","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-1185-053X","authenticated-orcid":false,"given":"Niklas","family":"Holz","sequence":"first","affiliation":[{"name":"Ophthalmology Section, Vetsuisse Faculty University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"Su\u00e1rez","sequence":"additional","affiliation":[{"name":"Clinic for Diagnostic Imaging, Vetsuisse Faculty University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Udo","family":"Hetzel","sequence":"additional","affiliation":[{"name":"Institute of Veterinary Pathology (IVPZ), Vetsuisse Faculty University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-5873-2866","authenticated-orcid":false,"given":"Antonella","family":"Rampazzo","sequence":"additional","affiliation":[{"name":"Ophthalmology Section, Vetsuisse Faculty University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Riccardo","family":"Stoppini","sequence":"additional","affiliation":[{"name":"Ophthalmology Section, Vetsuisse Faculty University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,3,7]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/eve.13275"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.d4844"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1463-5224.2008.00642.x"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/eve.12944"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1292\/jvms.16-0537"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.2746\/0425164044877404"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/01676830.2017.1423087"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.1990.196.10.1631"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.i37"},{"issue":"12","key":"e_1_2_10_11_1","first-page":"1339","article-title":"Mycotic Encephalitis, Sinus Osteomyelitis, and Guttural Pouch Mycosis in A 3\u2010Year\u2010Old Arabian Colt","volume":"52","author":"Hunter B.","year":"2011","journal-title":"Canadian Veterinary Journal"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3292.2011.00249.x"},{"key":"e_1_2_10_13_1","doi-asserted-by":"crossref","unstructured":"D.
