DED is well-studied in thyroid orbitopathy, but scarce data are available in patients with papillary thyroid carcinoma (PTC). Methods: We analyzed 29 PTC cases with radioactive iodine (RAI) treatment (Group 1), 22 PTC cases without RAI (Group 2), and 26 normal control individuals (Group 3). All participants were evaluated with the Ocular Surface Disease Index (OSDI), meibomian gland secretion quality, and lid margin grading. Non-contact meibography and non-invasive tear breakup time measurements were completed using the Sirius Scheimpflug camera. Thyrotropin (TSH), free thyroxine, and free triiodothyronine were measured. Results: TSH values were significantly lower in both patient groups than in controls (p &lt; 0.001). The proportion of participants with a lower meibomian gland secretion quality score \u2265 1 was 34.5% in Group 1, 22.7% in Group 2, and 7.1% in Group 3 (p = 0.002). There was a higher proportion of a meibomian gland atrophy score \u2265 1 in Groups 1 and 2 than in controls (p = 0.007). No differences were found between groups in lower lid margin score, Oxford values, upper meibomian gland expressibility or upper meibography scores (p = 0.485, p = 0.064, p = 0.256, p = 0.069). OSDI scores were higher in both PTC groups than in controls (6.25 and 8.12 vs. 2.52), with borderline overall significance (p = 0.050) and higher pairwise scores versus controls (both p = 0.034). Conclusions: Meibomian gland dysfunction was observed in PTC patients regardless of RAI treatment, suggesting that TSH suppression itself may contribute to the development of ocular surface changes.<\/jats:p>","DOI":"10.3390\/jcm15093336","type":"journal-article","created":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T09:55:39Z","timestamp":1777370139000},"page":"3336","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of Dry Eye Parameters in Patients with Papillary Thyroid Carcinoma"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2334-137X","authenticated-orcid":false,"given":"M\u00fcge","family":"Keskin","sequence":"first","affiliation":[{"name":"Department of Endocrinology and Metabolism, Ankara Bilkent City Hospital, Health Sciences University, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1348-7706","authenticated-orcid":false,"given":"Belma \u00d6zlem Tural","family":"Balsak","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Ankara Bilkent City Hospital, Health Sciences University, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neslihan","family":"Bayraktar","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Ankara Bilkent City Hospital, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c7a\u011flar","family":"Keskin","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Ankara Bilkent City Hospital, Health Sciences University, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatma Dilek","family":"Dellal Kahramanca","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Ankara Bilkent City Hospital, Health Sciences University, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6601-7791","authenticated-orcid":false,"given":"R\u0131za G\u00f6khan","family":"Baykal","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Ankara Bilkent City Hospital, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7826-9059","authenticated-orcid":false,"given":"Didem","family":"\u00d6zdemir","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Faculty of Medicine, Ankara Yildirim Beyazit University, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oya","family":"Topalo\u011flu","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Faculty of Medicine, Ankara Yildirim Beyazit University, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7437-1176","authenticated-orcid":false,"given":"Reyhan","family":"Ersoy","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Faculty of Medicine, Ankara Yildirim Beyazit University, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bekir","family":"\u00c7ak\u0131r","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Faculty of Medicine, Ankara Yildirim Beyazit University, Ankara 06800, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1284","DOI":"10.1158\/1055-9965.EPI-21-1440","article-title":"Cancer progress and priorities: Epidemiology of thyroid cancer","volume":"31","author":"Kitahara","year":"2022","journal-title":"Cancer Epidemiol.
