This case describes a patient who demonstrated ocular dipping: slow conjugate downward eye movements with a quick return to primary gaze. Ocular dipping is a rare phenomenon that was initially described in patients with hypoxic brain injury and has since been described in only a handful of cases. Dipping resides in a spectrum of spontaneous vertical eye movements, with ocular bobbing being the first of these described eye movements. Ocular bobbing is characterized by a fast downward movement followed by a slow return to the mid gaze position which is classically associated with pontine injury. Other vertical eye movements that can be seen in patients with a disorder of consciousness include other variations of ocular bobbing and dipping, vertical myoclonus, and small-amplitude mainly vertical movements.<\/jats:p>","DOI":"10.1177\/19418744251331649","type":"journal-article","created":{"date-parts":[[2025,4,29]],"date-time":"2025-04-29T23:31:54Z","timestamp":1745969514000},"page":"402-406","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Spontaneous Abnormal Vertical Eye Movements of Coma"],"prefix":"10.1177","volume":"15","author":[{"given":"Claire","family":"Allen","sequence":"first","affiliation":[{"name":"Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siena","family":"Duarte","sequence":"additional","affiliation":[{"name":"Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, MD, USA"},{"name":"Department of Neurology, University of California San Francisco (UCSF) School of Medicine, San Francisco, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaeho","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romergryko G","family":"Geocadin","sequence":"additional","affiliation":[{"name":"Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1112-7325","authenticated-orcid":false,"given":"Kemar E.","family":"Green","sequence":"additional","affiliation":[{"name":"Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,4,29]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/med\/9780199969289.001.0001"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.51.5.725"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1970.00480220062009"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.25.10.949"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1981.00510050063010"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410090216"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.3988\/jcn.2014.10.2.162"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/WNO.0000000000002063"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.3928\/01913913-20171129-01"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/0303-8467(82)90023-3"},{"key":"e_1_3_4_12_2","volume-title":"Galetta\u2019s Neuro-Ophthalmology: Diagnosis and Management","author":"Liu GT","year":"2019","unstructured":"Liu GT, Volpe NJ, Galetta SL, Liu V.
