Methods: Forty-three eyes were evaluated. Intraocular pressures at baseline and at the\nfirst, third, and sixth months after transscleral diode laser cyclophotocoagulation were compared.\nCiliary body thickness, ciliary muscle thickness, ciliary process thickness, iris root thickness, and\nscleral thickness were assessed at baseline and at the third and sixth months post-treatment.\nResults: Reductions in intraocular pressure were significant between baseline and the first\nmonth (p=0.018), third month (p&lt;0.001), and sixth month (p&lt;0.001) as well as between the first\nand third months (p=0.034) and the first and sixth months (p=0.036). Compared with baseline,\nintraocular pressure reduction rates at the first, third, and sixth months were 34.6%, 56.5%, and 55.3%,\nrespectively, while success rates were 30.2%, 62.8%, and 55.8%, respectively. Decreases in ciliary body\nthickness, ciliary muscle thickness, and ciliary process thickness were significant between baseline\nand the third month (p&lt;0.05) and between baseline and the sixth month (p&lt;0.05), whereas changes\nbetween the third and sixth months were not significant (p&gt;0.05). Iris root and scleral thicknesses did\nnot change after treatment (p&gt;0.05). At the third and sixth months, significant positive correlations\nwere observed between changes in intraocular pressure and changes in ciliary body thickness and ciliary\nprocess thickness (p&lt;0.05). Conclusions: To the best of our knowledge, this is one of the few studies\ncomprehensively investigating structural changes after transscleral diode laser cyclophotocoagulation\nusing ultrasound biomicroscopy. Moreover, the relationships between intraocular pressure changes\nand variations in the ciliary body, ciliary muscle, ciliary process, iris root, and scleral thicknesses were\nexamined in detail. Single-session treatment did not affect iris root or scleral thickness but significantly\nreduced ciliary body, ciliary muscle, and ciliary process thicknesses. Greater reductions in ciliary body\nand ciliary process thickness may contribute to more pronounced intraocular pressure reduction.<\/jats:p>","DOI":"10.5935\/0004-2749.2025-0043","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T18:47:20Z","timestamp":1786733240000},"page":"1-8","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of diode laser cyclophotocoagulation efficiency in refractory glaucoma and determination of structural changes using ultrasound biomicroscopy"],"prefix":"10.5935","volume":"89","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4307-3360","authenticated-orcid":false,"given":"Hakan","family":"\u00d6zt\u00fcrk","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9020-3810","authenticated-orcid":false,"given":"Bediz","family":"\u00d6zen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3948","published-online":{"date-parts":[[2026]]},"container-title":["Arquivos Brasileiros de Oftalmologia"],"original-title":[],"link":[{"URL":"https:\/\/www.scielo.br\/j\/abo\/a\/wSXN4V5VtNDXNtf3cGHcSXx\/?lang=en&ilang=en","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T18:47:21Z","timestamp":1786733241000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.scielo.br\/j\/abo\/a\/wSXN4V5VtNDXNtf3cGHcSXx\/?lang=en&ilang=en"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.5935\/0004-2749.2025-0043","relation":{},"ISSN":["0004-2749"],"issn-type":[{"value":"0004-2749","type":"print"}],"subject":[],"published":{"date-parts":[[2026]]}}}
