Computed Tomography Diagnostic Abilities for Open-Globe Injuries in Pediatric Versus Adult Patients

The aim of this study was to compare the role of computed tomography (CT) in the diagnosis of open-globe trauma and intraocular foreign body (IOFB) in pediatric and adult age groups.

Medical records of cases with open-globe trauma at Inonu University Hospital's Ophthalmology Emergency Service were retrospectively evaluated. Preoperative orbital CT images of the cases obtained at emergency services and their clinical and/or surgical findings were compared in pediatric and adult groups.

We included 47 eyes of 47 cases aged 18 years and below (pediatric group) and 85 eyes of 82 cases over 18 years (adult group). The mean ± SD age was 10.80 ± 5.11 years (range, 2-18 years) in the pediatric group and 46.34 ± 19.01 years (range, 19-82 years) in the adult group. Computed tomography images revealed 21.7% of the cases with corneal lacerations, 55.5% with scleral lacerations, and 91.6% with corneoscleral lacerations in the pediatric group, whereas the respective numbers were 48.4%, 66.6%, and 61.9% in the adult group. The detection rates of corneal penetrations and vitreous hemorrhage with CT were significantly lower in the pediatric group than in the adult group (P < 0.05). The CT scans diagnosed 66.6% of the pediatric cases and 90% of the adult cases with an IOFB.

Corneal lacerations and IOFBs can be missed, especially in the pediatric group, because the eye is smaller in adults. Pediatric patients with a history of ocular trauma should undergo an examination under general anesthesia followed by surgical exploration if necessary.
