The purpose of the present study was to assess the three-dimensional binocular eye movements that occur in response to the roll tilt. Furthermore, the study was intended to find out whether any asymmetry or disconjugacy of eye movements exists in 1 g environment.\n【Methods】Ten healthy subjects (6 males and 4 females) participated in this experiment. The subjects were tilted to the left or to the right on the naso-occipital axis up to 35 degrees (deg.). The eye movements were recorded and an analysis of these eye movements was performed using a video - oculographic method.\n【Results】In torsional eye movement, there was counter - rolling of the eyes in response to head tilt. In terms of horizontal eye movement, the left eye deviated towards the right during left ear down (LED) tilt, and the right eye deviated towards the left during right ear down (RED) tilt. There was no asymmetry in the performance of horizontal, vertical or torsional eye movements. There was no disconjugacy in the vertical or torsional eye movements, and in the horizontal eye movements disconjugacy was observed in which the lowermost eye to the tilt deviated towards the opposite side.\n【Conclusion】In normal subjects in a 1 g environment, each of the three eye movements was symmetrical during head tilt. There was disconjugacy observed in the horizontal eye movements. The deviation of the lowermost eye towards the opposite relative to the tilt direction may be explained by the anatomical and/or physiological characteristics of the utricular nerve projection to the abducens nucleus.\n","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"埼玉医科大学医学会"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0009506X","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-1031","subitem_source_identifier_type":"ISSN"}]},"item_10001_text_24":{"attribute_name":"記事区分","attribute_value_mlt":[{"subitem_text_value":"原著"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"杉崎, 一樹"}],"nameIdentifiers":[{"nameIdentifier":"1862","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小泉, 康雄"}],"nameIdentifiers":[{"nameIdentifier":"1863","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩村, 美生"}],"nameIdentifiers":[{"nameIdentifier":"1864","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"荒木, 隆一郎"}],"nameIdentifiers":[{"nameIdentifier":"1865","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加瀬, 康弘"}],"nameIdentifiers":[{"nameIdentifier":"1866","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池園, 哲郎"}],"nameIdentifiers":[{"nameIdentifier":"1867","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"八木, 聰明"}],"nameIdentifiers":[{"nameIdentifier":"1868","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugizaki, Kazuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1869","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koizumi, Yasuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1870","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwamura, Mio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1871","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Araki, Ryuichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1872","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kase, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1873","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikezono, Tetsuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1874","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yagi, Toshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1875","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-03-01"}],"displaytype":"detail","filename":"392_p121_129.pdf","filesize":[{"value":"755.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"3D analysis of binocular eye movement during head tilt","url":"https://saitama-med.repo.nii.ac.jp/record/525/files/392_p121_129.pdf"},"version_id":"24de6de8-bc32-4dd0-9894-e71012674c08"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"eye movements","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ocular counter rolling","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"binocular","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"symmetry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"disconjugacy","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"頭部傾斜時の眼球運動の３次元解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"頭部傾斜時の眼球運動の３次元解析"},{"subitem_title":"3D analysis of binocular eye movement during head tilt","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["74"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-01"},"publish_date":"2017-03-01","publish_status":"0","recid":"525","relation_version_is_last":true,"title":["頭部傾斜時の眼球運動の３次元解析"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-19T10:37:01.400980+00:00"}
