We performed a 17-year retrospective cohort study to report outcomes and risk factors for enucleation following open globe injuryto better aid clinicians counseling patients at OGI diagnosis.Methods: A retrospective cohort study of all patients who presented to the University of Michigan with open globe injury (OGI) and were surgically managed between January 2000 and July 2017 was conducted. At least 30 days of follow-up was required. All eyes that ultimately underwent enucleation following OGI were identified and their clinical course analyzed. The main outcome measured was the rate of enucleation after OGI.Results: There were 587 eyes meeting inclusion criteria. The mean patient age was 40.75 ± 25.1 (range 1– 91). 441/585 (75.4%) patients were male. Average follow-up time was 1029.9 ± 1285.9 days. 116/587 eyes (19.8%) required enucleation after OGI, with 81.9% undergoing enucleation less than 30 days from injury. In enucleated eyes, the mean presenting logMAR vision was 2.91 ± 0.47 (Snellen equivalent between hand motion and light perception). The most common mechanism of injury requiring enucleation was globe rupture, 89/116 (76.7%), with 14/116 (12.1%) penetrating injuries and 13/116 (11.2%) perforating injuries. The mean age of patients that underwent enucleation was 45.6 ± 22.5 (range 3– 91).Conclusion: Open globe injuries are often visually devastating and a significant number of cases ultimately require enucleation. Despite emergent closure within 24 hours, 19.8% of eyes managed for OGI at our institution required eventual enucleation. 81.2% of these eyes required enucleation within 30 days of injury. Wound length greater than 10 mm, uveal prolapse, higher zone of injury, IOFB, and RAPD were identified as risk factors that predict future need for enucleation.Keywords: ocular trauma, open globe repair, globe rupture, eye injury, enucleation
