    Abstract:
    Retinal hemorrhages are an integral part of the evaluation of abusive head trauma (AHT). Timely detection of retinal hemorrhage not only facilitates the diagnosis of AHT, but has the potential to prevent further abuse to the child and the siblings and to identify the abuser. The gold standard for diagnosing retinal hemorrhage is a dilated fundoscopy exam, which requires pharmacological dilation. As such, there is a small percentage of patients for whom the dilated fundoscopy exam might be delayed. Evolving literature suggests that MRI, specifically susceptibility-weighted imaging (SWI), of the orbits might provide an alternative diagnostic tool for noninvasively detecting retinal hemorrhages, particularly when there is a delay in administering the dilated fundoscopy exam. In this paper we review the utility of SWI for detecting retinal hemorrhages in abusive head trauma, including discussion of diagnostic limitations and future research.
