Abstract

PURPOSE: This study aimed to evaluate the mechanisms of injury and types of orbital fractures and their relation to concurrent commotio retinae.

METHODS: This retrospective study evaluated the records of patients with orbital fractures whose diagnoses had been confirmed by computer tomography between July 2017 and September 2019. Patient demographics, the circumstances of injury, ophthalmic examination results, and radiological findings were tabulated. Statistical analysis of the data used two-tailed student's t-tests, chi-squared tests, and odds ratio calculations. Statistical significance was set at p<0.05.

RESULTS: Of the 204 patients with orbital fractures included in this study, 154 (75.5%) were male. The mean age was 42.1 years. Orbital fractures involving one orbital wall (58.8%) were more common than those affecting multiple walls (41.2%). The majority of fractures affected the inferior wall (60.3%), with the medial walls being the next most frequently affected (19.6%). The most common cause of injury was assault (59.3%), and the second most common was falls (24%). Commotio retinae was observed in 20.1% of orbital fracture cases and was most associated with injuries caused by assault (OR=5.22, p<0.001) and least associated with those caused by falls (OR=0.06, p<0.001). Eye movement restrictions were more common in central than peripheral commotio (OR=3.79, p=0.015) and with medial wall fractures than fractures to other orbital walls (OR=7.16, p<0.001). The odds of commotio were not found to be higher in patients with multi-walled orbital fractures than in those with single-walled fractures (p=0.967).

CONCLUSIONS: In the study population, assault was the most common cause of orbital fractures and resulted in commotio retinae than other causes. Ophthalmologists should be aware of the likelihood of commotio retinae in patients with orbital fractures resulting from assault, regardless of the extent of the patient's injuries.
