Retinal hemorrhages in abusive head trauma

Brain injuries due to abusive head trauma (AHT) in infants are not rare and they are probably under-diagnosed. Retinal hemorrhages (RH) constitute a cardinal symptom of AHT and AHT is the most common cause of RH in infants next to childbirth. Retinoschisis with or without retinal folds is highly suggestive of AHT and never seen secondary to childbirth. Bilateral extensive RH that are too numerous to count, multilayered and extending to the peripheral retina in infants < 3 years of age, in combination with brain injury and in absence of leukemia, ruptured brain aneurysm/AVM, fatal head crush or known severe accidental trauma must be considered to be caused by AHT in the absence of any other compelling factors. The ophthalmologist has an important role and a responsibility in describing the pattern of RH and in evaluating the likelihood of the diagnosis in the medical report and in communication with pediatricians and child protection team.
