Extrapolated sagittal height values obtained during the natural eyelid position were typically greater than those obtained with eyelid retraction, most likely due to the amount of measured data available for extrapolation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/opo.13473","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T08:36:57Z","timestamp":1740127017000},"page":"627-636","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Agreement between extrapolated corneoscleral topographical data obtained during natural and retracted eyelid positions"],"prefix":"10.1007","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1770-527X","authenticated-orcid":false,"given":"Rohan P.
