Insights
Severe, multilayered retinal hemorrhages (RHs) with retinoschisis in infants are highly specific indicators of abusive head trauma, distinguishing it from other causes.
Area of Science:
- Ophthalmology
- Pediatrics
- Forensic Medicine
Background:
- Abusive head trauma (AHT) is a significant cause of infant morbidity and mortality.
- Retinal hemorrhages (RHs) are common findings in children with AHT.
Purpose of the Study:
- To review the evaluation of children with RHs.
- To differentiate RHs caused by AHT from other etiologies.
- To discuss the pathophysiology and distinguishing features of AHT-related RHs.
Main Methods:
- Review of existing literature on retinal hemorrhages in children.
- Focus on differential diagnosis and distinguishing features of AHT-related RHs.
- Discussion of ophthalmologic consultation indications and examination timing.
Main Results:
- Non-AHT causes of RHs typically present nonspecific patterns.
- Severe, multilayered RHs extending to the retinal periphery, especially with retinoschisis, are specific to AHT.
- Retinoschisis is rarely associated with accidental trauma, and such events are usually well-documented.
Conclusions:
- Ophthalmologic findings, particularly severe peripheral RHs with retinoschisis, are critical in diagnosing AHT.
- Distinguishing AHT-related RHs from other causes is crucial for appropriate child protection.
- Understanding the significance of specific RH patterns aids in timely diagnosis and intervention.
Abstract:
Abusive head trauma is an important cause of morbidity and mortality in infants and young children. Retinal hemorrhages (RHs) are frequently seen, particularly during dilated eye examination of these children. This review focuses on the evaluation of children with RH, with emphasis on the differential diagnosis, pathophysiology, and distinguishing features of RHs due to abusive head trauma. Many causes exist for RHs in infants and children. Most medical and accidental traumatic causes result in a pattern of RH that is nonspecific and not typical of the pattern and distribution of RHs seen in children with abusive head trauma. In children with intracranial hemorrhage and concerns for abuse, the finding of severe, multilayered RHs extending to the periphery of the retina is very specific for abuse as the cause of the findings, especially if retinoschisis is present. There are few other accidental traumatic mechanisms associated with retinoschisis, and the history of such a traumatic event is readily apparent. The indications for ophthalmologic consult, optimal timing of the eye examination, and significance of the findings are specifically discussed.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
