| Summary: | <h4>Purpose</h4>To identify risk factors for unexpected hypotony after transconjunctival sutureless vitrectomy (TSV).<h4>Methods</h4>In this retrospective observational study, we defined postoperative hypotony as intraocular pressure (IOP) < 6 mmHg on the day after TSV and performed multivariate analysis after dividing patients into hypotony and non-hypotony groups. Peripheral vitrectomy with scleral compression was performed for all patients and completed with normal IOP and no sutures.<h4>Results</h4>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 < 0.001), especially choroidal fold (47.5%) and hypotony maculopathy (2.2%). On dividing patients without tamponade into 3 AL-based groups, the ≥26-mm group had significantly higher hypotony incidence than the 23-26-mm group (33.3% vs. 18.4%; P = 0.024).<h4>Conclusion</h4>Longer AL and no tamponade usage influenced hypotony post-TSV. In patients with these factors, especially with AL ≥ 26 mm, surgeons may aggressively consider suturing sclerotomy to minimize hypotony-related complications. |
