| Summary: | <i>Background and Objectives</i>: To report the outcomes of cyanoacrylate tissue adhesive (CTA) in patients with corneal perforations and thinning. <i>Materials and Methods</i>: A retrospective interventional study of 83 eyes treated with CTA for corneal thinning or perforation at a single institution between 2010 and 2020. Primary endpoints leading to CTA failure, visual acuity, and surgical outcomes were evaluated. <i>Results</i>: At presentation, 55 (66%) had frank perforations and 28 (34%) had thinning or desmetocele. Univariate analysis showed that only multiple CTA applications were associated with CTA failure (<i>p</i> = 0.047). Multivariate analysis did not show any statistically significant variables associated with CTA failure. No variables were associated with the need for future surgery at 30 days or any further point. Older patients (<i>p</i> = 0.005), use of topical steroids before gluing (<i>p</i> = 0.03), corneal thinning (vs. perforation) (<i>p</i> = 0.02), location of pathology (<i>p</i> = 0.048), and multiple CTA applications (<i>p</i> = 0.046) were associated with worse visual outcomes in univariate analysis. Multivariate logistic regression analysis showed that older age (OR 1.05) and use of topical steroids before gluing (OR 3.84) showed higher odds, and systemic immunosuppression (OR 0.08) and single (versus multiple) CTA application (OR 0.11) showed lower odds of worse visual acuity (BCVA ≥ 20/200). The presence of an anterior chamber prior to gluing was associated with spontaneous dislocation of CTA (<i>p</i> = 0.015). Spontaneous dislocation versus manual removal of glue was not associated with final visual acuity (<i>p</i> = 0.7), nor was duration of glue on the cornea (<i>p</i> = 0.2). <i>Conclusions</i>: CTA remains a mainstay of management in patients with corneal thinning or perforation. Only multiple CTA applications were associated with CTA failure, and duration of glue on the cornea was not associated with final visual acuity. |
