Cardiac source of embolism is a\u00a0significant etiology of vascular embolization.\nThe important group is the so-called paradoxical embolism, which occurs when a\u00a0blood clot (embolus) is carried from the venous side of circulation to the arterial side via foramen ovale patens, what can manifests as ischemic stroke. Foramen ovale patens becomes a\u00a0risk factor for the stroke development only if there is a\u00a0peripheral source of embolism and at the same time there is a\u00a0hemodynamically significant right-left short circuit. Therefore, screening for the causes of cryptogenic stroke should include not only the detection of foramen ovale patens but also evaluation of the peripheral venous system, coagulation parameters and hemodynamic severity of a\u00a0right-left shunt. Neuroophthalmological aspects related to the described issues are discussed.<\/jats:p>","DOI":"10.31348\/2020\/38","type":"journal-article","created":{"date-parts":[[2022,2,1]],"date-time":"2022-02-01T13:59:03Z","timestamp":1643723943000},"page":"274-277","source":"Crossref","is-referenced-by-count":0,"title":["Can Visual Function Be Affected by an Open Foramen Ovale?"],"prefix":"10.31348","volume":"76","author":[{"given":"Petr","family":"V\u00fdborn\u00fd","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jozef","family":"\u010cmelo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16213","published-online":{"date-parts":[[2021,1,25]]},"reference":[{"key":"ref0","unstructured":"Popelov\u00e1 J.
