Predictive value of non-ocular findings for retinal haemorrhage in children evaluated for non-accidental trauma

An Update to Biomechanical and Biochemical Principles of Retinal Injury in Child Abuse

Abusive head trauma (AHT) is an extreme form of physical child abuse, a subset of which is shaken baby syndrome (SBS). While traumatic injury in children is most readily observed as marks of contusion on the body, AHT/SBS may result in internal injuries that can put the life of the child in danger. One pivotal sign associated with AHT/SBS that cannot be spotted with the naked eye is retinal injury (RI), an early sign of which is retinal hemorrhage (RH) in cases with rupture of the retinal vasculature. If not addressed, RI can lead to irreversible outcomes, such as visual loss. It is widely assumed that the major cause of RI is acceleration-deceleration forces that are repeatedly imposed on the patient during abusive shaking. Still, due to the controversial nature of this type of injury, few investigations have ever sought to delve into its biomechanical and/or biochemical features using realistic models. As such, our knowledge regarding AHT-/SBS-induced RI is significantly lacking. In this mini-review, we aim to provide an up-to-date account of the traumatology of AHT-/SBS-induced RI, as well as its biomechanical and biochemical features, while focusing on some of the experimental models that have been developed in recent years for studying retinal hemorrhage in the context of AHT/SBS.

Evidence-Based Screening to Optimize the Yield of Positive Ophthalmologic Examinations in Children Evaluated for Suspected Child Abuse

PURPOSE

To determine nonocular findings associated with significant retinal hemorrhage on dilated fundus examination in cases of suspected child abuse.

METHODS

This was a retrospective chart review from May 2014 to August 2021 at a level-1 trauma center. Two hundred seventy-four patients met the following inclusion criteria: (1) children 36 months and younger; (2) concern for child abuse; and (3) had an ophthalmology consultation. Through univariate and multivariate logistic regression, the study produced a screening algorithm for ophthalmic work-up in child abuse.

RESULTS

One or more abnormal neuroimaging findings had a statistically significant association with retinal hemorrhages and produced the strongest association with a univariate odds ratio of 170 (confidence interval: 10.245 to > 999.999). The multivariate model (P < .0001 with a c-statistic of 0.980) proposes using the following variables for predicting retinal hemorrhage on examination: abnormal neuroimaging, Glasgow Coma Scale score less than 15, altered mental status on examination, seizure activity, vomiting, bruising, scalp hematoma/swelling, and skull fractures.

CONCLUSIONS

This study elucidates clinical and imaging factors that correlate to retinal findings, validating previously studied variables and introducing new variables to be considered. The authors propose an evidence-based screening algorithm to increase the yield of positive dilated examinations and decrease the burden of potentially unnecessary child abuse ophthalmologic examinations.
