Peripheral vitrectomy with scleral compression was performed for all patients and completed with normal IOP and no sutures.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Eight-hundred and forty eyes of 748 consecutive patients who underwent 25-G or 27-G TSV were included. Postoperative hypotony occurred in 139 eyes (16.5%) and was associated with longer axial length (AL) (odds ratio [OR], 0.86; P = 0.001) and no tamponade usage (OR, 0.50; P = 0.001). Postoperative complications occurred more frequently in the hypotony group than in the non-hypotony group (51.1% vs. 11.3%, P &lt; 0.001), especially choroidal fold (47.5%) and hypotony maculopathy (2.2%). On dividing patients without tamponade into 3 AL-based groups, the \u226526-mm group had significantly higher hypotony incidence than the 23\u201326-mm group (33.3% vs. 18.4%; P = 0.024).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>Longer AL and no tamponade usage influenced hypotony post-TSV. In patients with these factors, especially with AL \u2265 26\u2009mm, surgeons may aggressively consider suturing sclerotomy to minimize hypotony-related complications.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0321135","type":"journal-article","created":{"date-parts":[[2025,4,28]],"date-time":"2025-04-28T17:22:13Z","timestamp":1745860933000},"page":"e0321135","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":6,"title":["Risk
