Abstract
To clarify the prognosis of corneal perforation, we compared the etiology and characteristics of patients with traumatic and non-traumatic corneal perforations. This retrospective observational study included patients treated for traumatic or non-traumatic corneal perforations at a single tertiary hospital from 1989 to 2019. The variables collected included the primary cause of corneal perforation, final best-corrected visual acuity (BCVA), and treatment administered. The initial treatment administered and treatment success rates were compared between the traumatic and non-traumatic groups. Multivariate linear regression analysis was performed to determine the predictors of final visual acuity. Ninety eyes of 90 patients (mean age, 61.1 ± 19.7years) were included. Traumatic and non-traumatic corneal perforations occurred in 40 (44.4%) and 50 eyes (55.6%), respectively. Among non-traumatic causes, infection and autoimmune disease were the causes for corneal perforation in 18 (20.0%) and 12 eyes (13.3%), respectively. The success rate for the closure of the perforated site with the initial procedure was significantly higher in traumatic corneal perforations than in non-traumatic corneal perforations (90.0% and 72.2%, respectively; p = 0.038). Patients with traumatic corneal perforation had significantly better final BCVA than those with non-traumatic corneal perforation (0.71 ± 1.18 and 1.52 ± 1.12, respectively; p = 0.0016). On multivariate analysis, older age and non-traumatic corneal perforation were significantly related to the final lower BCVA (p < 0.001 and p = 0.029, respectively). Traumatic corneal perforation demonstrated a significantly better prognosis than non-traumatic corneal perforation. It is critical to consider the primary cause of corneal perforation to anticipate prognosis.
