These can interfere with the standard neuropsychological assessment and complicate the interpretation of tests that use visual materials. However, information about the integrity of a patient's central visual field is often unavailable. We, therefore, designed a screening tool, the computerized visual field test (c\u2010<jats:styled-content style=\"fixed-case\">VFT<\/jats:styled-content>), specifically targeted at providing easily available, but rough, information about patients' central visual field. c\u2010<jats:styled-content style=\"fixed-case\">VFT<\/jats:styled-content> was tested in two samples of stroke patients. Eleven patients were tested on c\u2010<jats:styled-content style=\"fixed-case\">VFT<\/jats:styled-content> and on the Esterman test. Five patients were tested on c\u2010<jats:styled-content style=\"fixed-case\">VFT<\/jats:styled-content> and the Humphrey Visual Field Analyzer (<jats:styled-content style=\"fixed-case\">HFA<\/jats:styled-content>), central 10\u20102. Criterion validity of the c\u2010<jats:styled-content style=\"fixed-case\">VFT<\/jats:styled-content> was investigated by calculating quadrantwise intraclass correlation for both comparisons. For the <jats:styled-content style=\"fixed-case\">HFA<\/jats:styled-content> comparison, we also calculated point\u2010to\u2010point intraclass correlation, sensitivity, and specificity. Analyses revealed moderately good correspondence between c\u2010<jats:styled-content style=\"fixed-case\">VFT<\/jats:styled-content> and the Esterman test, and between c\u2010<jats:styled-content style=\"fixed-case\">VFT<\/jats:styled-content> and <jats:styled-content style=\"fixed-case\">HFA<\/jats:styled-content> 10\u20102, respectively. When looking specifically at test points within one degree of visual angle apart in the two tests, intraclass correlation increased. For these points, the sensitivity of c\u2010<jats:styled-content style=\"fixed-case\">VFT<\/jats:styled-content> was 0.89 and specificity was 0.97. While the c\u2010<jats:styled-content style=\"fixed-case\">VFT<\/jats:styled-content> is not designed to be diagnostic nor to replace the detailed visual field analysis, this study shows that it provides a reasonable screening of the central visual field. The test can easily be used and will be made freely available to neuropsychological clinicians and researchers.<\/jats:p>","DOI":"10.1111\/sjop.12546","type":"journal-article","created":{"date-parts":[[2019,5,27]],"date-time":"2019-05-27T04:23:02Z","timestamp":1558930982000},"page":"289-294","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A free and simple computerized screening test for visual field defects"],"prefix":"10.1111","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2183-0447","authenticated-orcid":false,"given":"Maria","family":"Nordfang","sequence":"first","affiliation":[{"name":"Department of Neurology Rigshospitalet Glostrup Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4342-4412","authenticated-orcid":false,"given":"Valdemar","family":"Uhre","sequence":"additional","affiliation":[{"name":"Danish Research Center for Magnetic Resonance Hvidovre Denmark"},{"name":"Research Unit, Child and Adolescent Mental Health Centre Copenhagen Denmark"},{"name":"Department of Clinical Medicine Faculty of Health Sciences University of Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7267-3114","authenticated-orcid":false,"given":"Ro Julia","family":"Robotham","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Copenhagen Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheila J.","family":"Kerry","sequence":"additional","affiliation":[{"name":"Institute Cognitive Neuroscience University College London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1661-7438","authenticated-orcid":false,"given":"Jette Lautrup","family":"Frederiksen","sequence":"additional","affiliation":[{"name":"Department of Neurology Rigshospitalet Glostrup Denmark"},{"name":"Department of Clinical Medicine Faculty of Health Sciences University of Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5849-5160","authenticated-orcid":false,"given":"Randi","family":"Starrfelt","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Copenhagen Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,5,26]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/1545968312454683"},{"key":"e_1_2_7_3_1","volume-title":"Humphrey Field Analyzer II \u2013 i series: User's Guide","author":"Carl Zeiss Meditec Inc","year":"2003"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0186224"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0161-6420(82)34647-3"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.9734\/OR\/2016\/23272"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp-2012-302270"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcm.2016.02.012"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/1545968315585355"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1038\/eye.2016.25"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(01)06448-0"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneumeth.2006.11.017"},{"issue":"10","key":"e_1_2_7_13_1","article-title":"Generating stimuli for neuroscience using PsychoPy","volume":"2","author":"Peirce J.
