Abstract

PURPOSE: This study aims to estimate the incidence of ophthalmologic pathology at presentation of patients with orbital fracture to a level I trauma centre and the most significant associated risk factors.

METHODS: A total of 244 patients with 278 fractured orbits over a 2-year period at a level I trauma centre were reviewed. The primary outcome was the incidence of urgent ophthalmologic pathology, defined as requiring attention without delay. Patient demographics, history, findings on radiographic imaging, and physical examination findings at initial and follow-up examinations were recorded. Odds ratios with 95% confidence intervals were calculated.

RESULTS: On initial examination and follow-up, 9.7% of orbits had ophthalmologic pathology. Only 3 patients (1.1%) had urgent pathology, including orbital compartment syndrome and globe rupture, whereas 22 patients (7.9%) had semiurgent pathology and 4 patients (1.4%) had nonurgent pathology. Subjective decreased vision (odds ratio [OR] = 3.5; p = 0.021), assault-related injuries (OR = 2.4; p = 0.036), work-related injuries (OR = 7.7; p = 0.004), afferent pupillary defect (OR = 19.2; p = 0.017), anisocoria (OR = 7.8; p = 0.001), and symmetrical extraocular movement limitation (OR = 5.2; p = 0.003) and fixed pupil (OR = 16.9; p < 0.001) had statistically significant odds ratios associated with pathology. Patient sex, eye involved, intoxication, anticoagulation, and antiplatelets, as well as previous ocular surgery, were not associated with pathology.

CONCLUSIONS: Most orbital fractures do not present with ophthalmologic pathology. Subjective vision loss, history of assault or work trauma, and pupil abnormalities on examination were the greatest risk factors for pathology. Our results highlight the most important factors on patient presentation that should prompt first responders to seek urgent ophthalmologic consultation.
