Two recording techniques were used to control for artifacts: infrared video\u2010oculography and infrared scleral reflection techniques. Head movements were also recorded with 2 different accelerometers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We recorded ocular oscillations in both patients (microtremor). Ocular tremor was accompanied by a recordable (but clinically nonvisible) head tremor of equal fundamental frequency and high coherence with both the eye oscillation and a recordable limb tremor. The eye movements were in the opposite direction to the head oscillation (ie, compensatory) and were suppressed by head restraint. There was no subjective oscillopsia, nor ocular tremor on fundoscopy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The \u201cocular tremor\u201d observed in patients with PD disease is a compensatory eye movement secondary to transmitted head tremor, in agreement with clinical wisdom that these patients do not report oscillopsia. \u00a9 2013 <jats:italic>Movement<\/jats:italic> Disorder Society<\/jats:p><\/jats:sec>","DOI":"10.1002\/mds.25342","type":"journal-article","created":{"date-parts":[[2013,2,6]],"date-time":"2013-02-06T15:11:53Z","timestamp":1360163513000},"page":"534-537","source":"Crossref","is-referenced-by-count":29,"title":["Ocular Tremor in Parkinson's Disease Is Due to Head Oscillation"],"prefix":"10.1002","volume":"28","author":[{"given":"Diego","family":"Kaski","sequence":"first","affiliation":[{"name":"Department of Neurosciences Imperial College London Charing Cross Hospital London United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tabish A.","family":"Saifee","sequence":"additional","affiliation":[{"name":"Sobell Department of Motor Neuroscience and Movement Disorders UCL Institute of Neurology 33 Queen Square London United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Buckwell","sequence":"additional","affiliation":[{"name":"Department of Neurosciences Imperial College London Charing Cross Hospital London United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adolfo M.","family":"Bronstein","sequence":"additional","affiliation":[{"name":"Department of Neurosciences Imperial College London Charing Cross Hospital London United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,2,6]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1001\/archneurol.2012.70"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrneurol.2012.89"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.42.8.1527"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1089\/tmj.2011.0132"},{"key":"e_1_2_7_6_1","volume-title":"The Neurology of Eye Movements","author":"Leigh RJ","year":"2006"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410030422"},{"key":"e_1_2_7_8_1","volume-title":"Handbook of Tremor Disorders","author":"SEB M","year":"1995"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1615\/CritRevBiomedEng.v35.i5.10"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.42.8.705"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/00002060-196604000-00003"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/mds.20918"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1965.00470020094013"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/106.1.153"}],"container-title":["Movement Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmds.25342","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mds.25342","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T12:47:38Z","timestamp":1760964458000},"score":1,"resource":{"primary":{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/10.1002\/mds.25342"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,2,6]]},"references-count":13,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2013,4]]}},"alternative-id":["10.1002\/mds.25342"],"URL":"https:\/\/doi.org\/10.1002\/mds.25342","archive":["Portico"],"relation":{},"ISSN":["0885-3185","1531-8257"],"issn-type":[{"value":"0885-3185","type":"print"},{"value":"1531-8257","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,2,6]]}}}
