Abstract
PURPOSE
The purpose of this study was to describe the clinical characteristics, management, and outcomes of orbital blow-in fractures involving compression of the globe by bone fragments.
METHODS
A retrospective case series and systematic literature review were performed.
RESULTS
Three male patients (mean age 29 years) with orbital blow-in fractures causing globe indentation presented with extraocular movement restriction, choroidal folds, and B-scan ultrasonography demonstrating deformation of the globe contour by a hyperechoic bone fragment. All underwent surgical repair within 1 day of presentation resulting in improved visual outcomes. An additional 10 cases were identified in the literature review. The majority of patients were male (80%) with a mean age of 29 years. Fractures originated primarily from the lateral orbital wall (50%) or the orbital roof (40%). Globe compression was evident on CT of the orbit (100%) and ultrasonography (30%). Common presenting signs included decreased visual acuity (70%), restriction of supraduction (40%) or abduction (40%), choroidal folds (30%), brow laceration (40%), periorbital edema (40%), and hypoglobus (40%). Most patients underwent surgical intervention (80%) involving fracture reduction (50%) or fragment removal (38%). Reported postsurgical outcomes were excellent with resolution of diplopia, motility, and visual acuity.
CONCLUSION
Globe indentation from blow-in fractures are rare. Clinicians should be suspicious in cases of high-velocity trauma to the superolateral orbit with hypoglobus, motility limitation, and indentation of the globe upon dilated exam. Prompt diagnosis and early surgical removal of the compressive orbital bone fragments in a multidisciplinary fashion can lead to good visual, functional, and cosmetic outcomes.
