A comprehensive eye exam was conducted, which included refraction, assessment of far and near vision acuity, and contrast sensitivity measurements. To check for the nystagmus, a videonystagmography was used. The tests were carried out in three modes: without any correction, with optical correction, and with correction using base-out prisms in three different powers, including 4, 6, and 8 prism diopters.\nRESULTS: Totally 23 patients with average age of 28.65\u00b112.13 were examined. It was found that the use of optical correction and optical correction with prisms resulted in a statistically significant improvement in both far (at least: P&lt;0.006) and near visual acuity (at least: P&lt;0.001 except for prism 8; P&lt;0.02). In addition, contrast sensitivity significantly improved at all low and medium frequencies except for correction with prism 8 in frequency 1.5 (at least: P&lt;0.01 except for prism 4, frequency 6; P=0.04). no significant improvement was observed in the evaluation of nystagmus characteristics.\nCONCLUSION: Optical correction with a prism can improve visual acuity and some spatial frequencies, but failed to improve nystagmus parameters.<\/jats:p>","DOI":"10.18240\/ijo.2024.10.13","type":"journal-article","created":{"date-parts":[[2024,9,18]],"date-time":"2024-09-18T06:53:24Z","timestamp":1726642404000},"page":"1864-1868","source":"Crossref","is-referenced-by-count":3,"title":["Effect of prisms on visual acuity, contrast sensitivity and nystagmus in patients with albinism"],"prefix":"10.18240","volume":"17","author":[{"name":"Department of Optometry, School of Rehabilitation, Shahid Beheshti University of Medical Sciences, Tehran 1616913111, Iran","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryam","family":"Dashti","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Majid","family":"Ashrafi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Audiology, School of Rehabilitation, Shahid Beheshti University of Medical Sciences, Tehran 1616913111, Iran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saeed","family":"Rahmani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Optometry, School of Rehabilitation, Shahid Beheshti University of Medical Sciences, Tehran 1616913111, Iran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seyyed Mehdi","family":"Tabatabaei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"School of Rehabilitation, Shahid Beheshti University of Medical Sciences, Tehran 1616913111, Iran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7543","container-title":["International Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"http:\/\/ies.ijo.cn\/en_publish\/2024\/10\/20241013.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,9,18]],"date-time":"2024-09-18T06:53:32Z","timestamp":1726642412000},"score":1,"resource":{"primary":{"URL":"http:\/\/ies.ijo.cn\/gjyken\/ch\/reader\/view_abstract.aspx?file_no=20241013&flag=1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,10,18]]},"references-count":0,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2024,10,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2024.10.13","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"value":"2222-3959","type":"print"},{"value":"2227-4898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,10,18]]}}}
