Objectives:
Corneal thinning and perforation are ocular emergencies necessitating urgent intervention to prevent visual impairment or enucleation. Cyanoacrylate tissue adhesive is frequently used to maintain globe integrity in these cases. However, gaps remain in understanding the outcomes of corneal gluing and the factors influencing its efficacy. This case series evaluates the clinical characteristics and outcomes of glue application in corneal thinning and perforation.
Methods:
A retrospective chart review was conducted on patients treated for corneal thinning and perforation at the University of Florida between January 2012 and May 2023. Demographic data, clinical history, glue application details, and posttreatment outcomes were collected and analyzed.
Results:
The study included 128 eyes from 125 subjects. Corneal perforation was found in 71 eyes (55.5%), mostly centrally (49.2%). The leading cause of perforation/thinning was microbial infection (45.3%). The average number of glue applications per eye was 1.66. Within 1 month, 23 patients (18.0%) required only glue reapplication, 37 (28.9%) required surgical intervention (regardless of glue reapplication), and 68 (53.1%) required no further treatment. Factors significantly linked to gluing failure (requiring surgery within 1 month) in univariate analysis included large perforation size, microbial infection, ocular surface disorder, single glue application, and indirect application via sterile drape. Multivariate analysis showed that only large perforation size was significantly associated with gluing failure.
Conclusion:
Corneal glue application is an effective temporizing measure for corneal thinning and perforation, with multiple applications potentially providing added stability to the globe. However, the need for surgical intervention is high.
