Intravenous thrombolysis (IVT) with alteplase in a time window\u2009&lt;\u20094.5\u00a0h may lead to a favorable outcome. Purpose of this study was to investigate the feasibility, efficacy and safety of IVT in patients classified as functionally blind.\n<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>We conducted a retrospective observational study of NA-CRAO-patients. All patients underwent an ophthalmological and neurological examination including cerebral magnetic resonance imaging (MRI) for assessment of additional stroke lesions. Patients were treated either conservatively or with IVT within 4.5\u00a0h. Visual acuity (VA) was evaluated in logMAR and a categorical analysis was performed.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Thirty-seven patients were included in the study, 21 patients in the conservative treatment group (CTG) and 16 patients in the IVT group. The median logMAR visual acuity at admission and discharge was similar in both groups. The medium symptom to treatment time in the IVT group was 158.0\u00a0min. 3 patients (19%) of the IVT group showed a favorable outcome, all CTG patients remained at the level of functional blindness. No serious adverse events were observed after IVT. MRI showed additional acute stroke in over one-third of the patients (<jats:italic>n<\/jats:italic>\u2009=\u200914).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Early intravenous thrombolysis therapy according to the current stroke protocol n a time window up to 4.5\u00a0h after the onset of symptoms was feasible and might be a potential treatment option for NA-CRAO. Patients with NA-CRAO are at very high risk of ischemic stroke and MRI should be done in all patients for optimized treatment and secondary stroke prevention. A prospective randomized study is required.\n<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00415-022-11439-7","type":"journal-article","created":{"date-parts":[[2022,10,28]],"date-time":"2022-10-28T13:12:46Z","timestamp":1666962766000},"page":"891-897","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Thrombolysis in central retinal artery occlusion: a retrospective observational study"],"prefix":"10.1007","volume":"270","author":[{"given":"Florian Philipp","family":"Raber","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian Vincent","family":"Gmeiner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens","family":"Dreyhaupt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Armin","family":"Wolf","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albert Christian","family":"Ludolph","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens Ulrich","family":"Werner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Kassubek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9004-4335","authenticated-orcid":false,"given":"Katharina","family":"Althaus","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,10,28]]},"reference":[{"key":"11439_CR1","doi-asserted-by":"publisher","first-page":"177","DOI":"10.1007\/s00347-016-0432-4","volume":"144","author":"N Feltgen","year":"2017","unstructured":"Feltgen N, Pielen A (2017) Retinal artery occlusion.
