Insights
Accidental severe head trauma in neonates can cause retinal hemorrhages (RHs) and peripapillary intrascleral hemorrhages. These findings, previously thought unique to abusive head trauma, highlight the need for careful differential diagnosis.
Area of Science:
- Ophthalmology
- Pediatric Pathology
- Forensic Medicine
Background:
- Retinal hemorrhages (RHs) are often investigated in cases of suspected child abuse.
- Peripapillary intrascleral hemorrhages (PIH) have been considered pathognomonic for abusive head trauma (AHT).
- Current guidelines suggest avoiding postmortem eye removal in cases of clear accidental death.
Observation:
- Two neonates experienced severe accidental in utero head injuries.
- Autopsies revealed extensive RHs, optic nerve sheath hemorrhages, and PIH in both neonates.
- Neither infant had a documented clinical fundal examination prior to death.
Findings:
- The presence of RHs and PIH in neonates with accidental head trauma challenges their exclusive association with AHT.
- Accidental severe head injuries, even in utero, can mimic findings typically attributed to abuse.
- This underscores the importance of considering non-abusive etiologies for these ocular findings.
Implications:
- Findings necessitate a broader differential diagnosis for RHs and PIH in neonates.
- Rethinking diagnostic criteria for AHT may be required.
- Careful clinical evaluation and consideration of accidental trauma are crucial in interpreting these pediatric autopsy findings.
Abstract:
The American Academy of Pediatrics' Committee on Child Abuse and Neglect, Section on Ophthalmology, acknowledges that searching for retinal hemorrhages (RHs) in infants only in cases of suspected of abuse creates selection bias. However, they also recommend that postmortem eye removal might not be indicated "in children who have clearly died from witnessed severe accidental head trauma or otherwise readily diagnosed systemic medical conditions." Although infrequently described in the child abuse literature, peripapillary intrascleral hemorrhages (bleeding in the sclera at the optic nerve insertion)--putatively from severe repetitive acceleration/deceleration forces with or without blunt head trauma--have been considered essentially pathognomonic for abusive head trauma (shaken baby syndrome). We present two neonates who sustained accidental, severe in utero head injuries and had associated extensive RHs and optic nerve sheath hemorrhages with peripapillary intrascleral hemorrhages detected at autopsy. Neither neonate had a documented clinical fundal examination in the intensive care unit.
