Eyes or lies? Navigating ocular pathology controversies in infant head trauma.
For years, the medical community has believed that specific ocular pathologies, including retinal hemorrhages, retinoschisis, macular folds, peripapillary intrascleral hemorrhages, and perioptic nerve sheath hemorrhages, are markers of inflicted pediatric injury with medicolegal significance. The mechanism of injury responsible for these findings was believed to be shaking, impact, or a combination thereof, each with serious legal implications. Despite growing skepticism over the last four decades, a pervasive opinion exists that shaking and/or impact trauma exert “shearing” forces to the eye structures. This proposition, particularly in relation to retinal abnormalities, hinges on the unvalidated “vitreoretinal traction” (VRT) theory. If VRT provides the true pathophysiological basis for intra-ocular hemorrhages, then this finding implies intense force application to an infant’s head. However, extensive reviews of literature and case experience suggest that these pathologies are not exclusively linked to head trauma, particularly deliberate injury. Notably, the foundational research often cited to establish the specificity of ocular pathology in child abuse has undergone considerable scrutiny, with critiques targeting its circular logic and other biases. Thus, a comprehensive and cautious evaluation is needed for the diagnostic value of ocular pathology in child abuse cases.
