The current study investigated whether an extremely long period of blindness might also cause a permanent impairment of visual performance, even in a case of adult-onset blindness. We examined KP, a 71-year-old man who underwent a successful sight-restoring operation after 53 years of blindness. A set of psychophysical tests designed to assess KP's face perception, object recognition, and visual space perception abilities were conducted six months and eight months after the surgery. The results demonstrate that regardless of a lengthy period of normal vision and rich pre-accident perceptual experience, KP did not fully integrate this experience, and his visual performance remained greatly compromised. This was particularly evident when the tasks targeted finer levels of perceptual processing. In addition to the decreased robustness of his memory representations, which was hypothesized as the main factor determining visual impairment, other factors that may have affected KP's performance were considered, including compromised visual functions, problems with perceptual organization, deficits in the simultaneous processing of visual information, and reduced cognitive abilities.<\/jats:p>","DOI":"10.1068\/i0611","type":"journal-article","created":{"date-parts":[[2013,10,26]],"date-time":"2013-10-26T07:51:48Z","timestamp":1382773908000},"page":"498-507","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":12,"title":["Vision after 53 Years of Blindness"],"prefix":"10.1177","volume":"4","author":[{"given":"Radovan","family":"\u0160ikl","sequence":"first","affiliation":[{"name":"Institute of Psychology, Academy of Sciences of the Czech Republic, Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michal","family":"\u0160ime\u010dek","sequence":"additional","affiliation":[{"name":"Institute of Psychology, Academy of Sciences of the Czech Republic, Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michaela","family":"Porubanov\u00e1-Norquist","sequence":"additional","affiliation":[{"name":"Institute of Psychology, Academy of Sciences of the Czech Republic, Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ond\u0159ej","family":"Bezd\u00ed\u010dek","sequence":"additional","affiliation":[{"name":"Department of Neurology, First Faculty of Medicine, Charles University in Prague, Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Kreml\u00e1\u010dek","sequence":"additional","affiliation":[{"name":"Department of Pathophysiology, Faculty of Medicine in Hradec Kr\u00e1lov\u00e9, Charles University in Prague, Hradec Kr\u00e1lov\u00e9, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavel","family":"Stod\u016flka","sequence":"additional","affiliation":[{"name":"Gemini Eye Clinic, Zl\u00edn, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ione","family":"Fine","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of Washington, Seattle, WA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuri","family":"Ostrovsky","sequence":"additional","affiliation":[{"name":"Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2013,12,1]]},"reference":[{"key":"bibr1-i0611","doi-asserted-by":"publisher","DOI":"10.1080\/14640747408400393"},{"key":"bibr2-i0611","doi-asserted-by":"publisher","DOI":"10.3758\/BF03210312"},{"key":"bibr3-i0611","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.70.8.607"},{"key":"bibr4-i0611","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/114.4.1523"},{"key":"bibr5-i0611","first-page":"864","volume-title":"Encyclopedia of perception","author":"Fine I.","year":"2009"},{"key":"bibr6-i0611","doi-asserted-by":"publisher","DOI":"10.1038\/nn1102"},{"key":"bibr7-i0611","volume-title":"Recovery from early blindness: A case study","author":"Gregory R.
