Methods: In all, 156 eyes of post-COVID-19 patients and 98 eyes of subjects from a control group were enrolled in our study. BCVA, intra ocular pressure (IOP) measurement, fundus examination, and OCT images, including macular cube, OCT-RNFL, and angio-OCT 6 \u00d7 6 mm examinations, were performed for both groups. The measurements were acquired using Swept Source OCT DRI OCT Triton. In the post-COVID-19 group, 762 OCT protocols were obtained. For statistical analysis, parameters from only one eye from each subject were taken. Results: In the measured parameters, no significant differences were observed, i.e., central macular thickness (p = 0.249); RNFL (p = 0.104); FAZ (p = 0.63); and vessel density of superficial retinal vascular plexus in central (p = 0.799), superior (p = 0.767), inferior (p = 0.526), nasal (p = 0.402), and temporal (p = 0.582) quadrants. Furthermore, a slit-lamp examination did not reveal any COVID-19-related abnormalities. Conclusion: OCT examination did not detect any significant changes in morphology or morphometry of the optic nerve, retina, or the retina vessels due to COVID-19.<\/jats:p>","DOI":"10.3390\/jcm10153233","type":"journal-article","created":{"date-parts":[[2021,7,22]],"date-time":"2021-07-22T22:35:31Z","timestamp":1626993331000},"page":"3233","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Retinal OCT Findings in Patients after COVID Infection"],"prefix":"10.3390","volume":"10","author":[{"given":"Dominika","family":"Szkodny","sequence":"first","affiliation":[{"name":"Chair and Clinical Department of Ophthalmology, Faculty of Medical Sciences, Zabrze Medical University of Silesia in Katowice, 40-760 Katowice, Poland"},{"name":"Department of Ophthalmology, District Railway Hospital in Katowice, 40-760 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6707-5790","authenticated-orcid":false,"given":"Edward","family":"Wyl\u0119ga\u0142a","sequence":"additional","affiliation":[{"name":"Chair and Clinical Department of Ophthalmology, Faculty of Medical Sciences, Zabrze Medical University of Silesia in Katowice, 40-760 Katowice, Poland"},{"name":"Department of Ophthalmology, District Railway Hospital in Katowice, 40-760 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulina","family":"Sujka-Franczak","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, District Railway Hospital in Katowice, 40-760 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1116-097X","authenticated-orcid":false,"given":"Edyta","family":"Chlasta-Twardzik","sequence":"additional","affiliation":[{"name":"Chair and Clinical Department of Ophthalmology, Faculty of Medical Sciences, Zabrze Medical University of Silesia in Katowice, 40-760 Katowice, Poland"},{"name":"Department of Ophthalmology, District Railway Hospital in Katowice, 40-760 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1573-9353","authenticated-orcid":false,"given":"Rafa\u0142","family":"Fiolka","sequence":"additional","affiliation":[{"name":"Chair and Clinical Department of Ophthalmology, Faculty of Medical Sciences, Zabrze Medical University of Silesia in Katowice, 40-760 Katowice, Poland"},{"name":"Department of Ophthalmology, District Railway Hospital in Katowice, 40-760 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz","family":"Tomczyk","sequence":"additional","affiliation":[{"name":"Temporary Hospital of Health Care Facility of the Ministry of the Interior and Administration in Katowice, 40-163 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Wyl\u0119ga\u0142a","sequence":"additional","affiliation":[{"name":"Chair and Clinical Department of Ophthalmology, Faculty of Medical Sciences, Zabrze Medical University of Silesia in Katowice, 40-760 Katowice, Poland"},{"name":"Department of Ophthalmology, District Railway Hospital in Katowice, 40-760 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"259","DOI":"10.1038\/s41569-020-0360-5","article-title":"COVID-19 and the cardiovascular system","volume":"17","author":"Zheng","year":"2020","journal-title":"Nat.
