We retrospectively evaluated CT findings in 44 patients with TON. Mid-facial fractures, extraconal and intraconal hematomas, hematomas along the optic nerve and the posterior globe, optic canal fracture, nerve impingement by optic canal fracture fragment, and extraconal and intraconal emphysema were evaluated. CT variables of patients with and without available VA were compared. VA was converted into logarithm of the minimum angle of resolution (logMAR) to provide a numeric scale for the purpose of statistical analysis. The risk factors related to poor VA on univariate analysis were as follows: intraconal hematoma [median logMAR −4.7 versus −1.15, p = 0.016] and hematoma along the optic nerve [median −4.7 versus −1.3, p = 0.029]. Intraconal hematoma was the best predictor of poor VA (coefficient, 1.01; SE, 0.34; and p = 0.008). Receiver operating characteristic (ROC) curve analysis showed that the presence of intraconal hematoma and hematoma along the optic nerve predicted poor VA (logMAR of −3.7 or lower) with an area under the curve of 0.8 and 0.85, respectively. TON patients at higher risk of severe visual impairment may be identified based on admission facial CT.
