PION is a distinct clinical entity, caused by ischemia of the posterior part of the optic nerve. These eyes presented with a visual acuity varying from normal to no light perception, optic nerve-related visual field defects, and no fundus abnormality (on ophthalmoscopy or fluorescein fundus angiography) at the onset of the disease and for about a month thereafter, but after about 5\u20136 weeks the optic disc developed atrophic changes. The pathogenesis, differential diagnosis and possible management of PION are discussed.<\/jats:p>","DOI":"10.1159\/000309085","type":"journal-article","created":{"date-parts":[[2010,3,31]],"date-time":"2010-03-31T05:08:54Z","timestamp":1270012134000},"page":"29-41","source":"Crossref","is-referenced-by-count":88,"title":["Posterior Ischemic Optic Neuropathy"],"prefix":"10.1159","author":[{"given":"Sohan Singh","family":"Hayreh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,30]]},"container-title":["Ophthalmologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000309085","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T06:59:46Z","timestamp":1777705186000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000309085"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,30]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000309085","archive":["Portico"],"relation":{},"ISSN":["0030-3755","1423-0267"],"issn-type":[{"value":"0030-3755","type":"print"},{"value":"1423-0267","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,30]]}}}
