Ophthalmologic findings in abusive head trauma

Abusive head trauma (AHT) is a form of child physical abuse in young children and our understanding of its implications has increased over time. Infants under 2 years are at highest risk for AHT, however, the Center for Disease Control and Prevention's (CDC) definition includes children up to 5 years. The most common mechanism for these injuries is rapid acceleration and deceleration with rotation of the head. Most often, one thinks of this occurring if a young child is shaken but it can also result from impact or a combination of shaking and impact. There has been a historical shift in the name of this diagnosis from Shaken Baby Syndrome (SBS) to AHT for this very reason, as there is no one specific way to obtain the injuries seen in abusive head trauma. The same mechanisms causing injuries to the brain can cause injuries to the eye and can either directly or indirectly affect vision. In this article, we will examine the eye findings that are common in children with AHT, how these findings are similar or different from those in other disease processes, and what the visual outcomes are for these children.
