Participants underwent optical coherence tomography imaging before and at 1 and 4h following FFP2\/N95 facemask wear. The last imaging session was performed 1h after FFP2\/N95 removal. Retinal thickness, CT, RNFLT, and GCLT were assessed at each session. Vital parameters were also assessed.\nRESULTS: The pulse rate of the subjects significantly decreased at 1 and 4h compared to baseline values (P&lt;0.05). No significant changes in retinal thickness, RNFLT, and GCLT were observed in the study. CT profile showed a significant increase at all measured locations except 1-mm temporal, 1-mm inferior and 2-mm inferior points following FFP2\/N95 wear which turned to baseline values after FFP2\/N95 removal. Pulse rate and CT changes at 4h were significantly correlated (P&lt;0.05).\nCONCLUSION: Parasympathetic activation during FFP2\/N95 facemask wear might have a role on elevated CT measurements in healthy individuals by virtue of increased choroidal blood flow.<\/jats:p>","DOI":"10.18240\/ijo.2022.11.13","type":"journal-article","created":{"date-parts":[[2022,10,25]],"date-time":"2022-10-25T03:06:51Z","timestamp":1666667211000},"page":"1821-1828","source":"Crossref","is-referenced-by-count":0,"title":["Effect of FFP2\/N95 facemask wear on retinal and choroidal thickness profile in healthy subjects"],"prefix":"10.18240","volume":"15","author":[{"name":"Department of Ophthalmology, University of Health Sciences, Trabzon Kanuni Training and Research Hospital, Trabzon 61040, Turkey","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Betul Onal","family":"Gunay","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmet","family":"Kalkisim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Ophthalmology, University of Health Sciences, Trabzon Kanuni Training and Research Hospital, Trabzon 61040, Turkey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cenap Mahmut","family":"Esenulku","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Ophthalmology, University of Health Sciences, Trabzon Kanuni Training and Research Hospital, Trabzon 61040, Turkey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elif Betul","family":"Turkoglu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Ophthalmology, Akdeniz University Hospital, Antalya  07070, Turkey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7543","container-title":["International Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"http:\/\/ies.ijo.cn\/en_publish\/2022\/11\/20221113.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,10,25]],"date-time":"2022-10-25T03:07:13Z","timestamp":1666667233000},"score":1,"resource":{"primary":{"URL":"http:\/\/ies.ijo.cn\/gjyken\/ch\/reader\/view_abstract.aspx?file_no=20221113&flag=1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,11,18]]},"references-count":0,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2022,11,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2022.11.13","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"type":"print","value":"2222-3959"},{"type":"electronic","value":"2227-4898"}],"subject":[],"published":{"date-parts":[[2022,11,18]]}}}
