Summary
Paediatric abusive head injury, often from shaken baby syndrome, causes severe outcomes. Retinal hemorrhages are a key sign, aiding diagnosis in these critical cases.
Area of Science:
- Ophthalmology
- Paediatric Medicine
- Forensic Pathology
Background:
- Paediatric abusive head injury (AHI) carries severe consequences, including high mortality and neurological damage.
- Repetitive acceleration-deceleration forces, characteristic of shaken baby syndrome, are a primary mechanism.
- Retinal hemorrhages are present in approximately 85% of AHI cases, often extensive and involving multiple retinal layers.
Purpose of the Study:
- To highlight the diagnostic significance of ocular findings in paediatric abusive head injury.
- To emphasize the role of ophthalmologists and autopsy in diagnosing AHI.
- To discuss the mechanism and clinical presentation of traumatic macular retinoschisis in AHI.
Main Methods:
- Review of clinical presentations and autopsy findings in paediatric abusive head injury cases.
- Analysis of the characteristics of retinal hemorrhages and traumatic macular retinoschisis.
- Correlation of ocular findings with systemic and laboratory data.
Main Results:
- Retinal hemorrhages (preretinal, intraretinal, subretinal) are a cardinal sign of AHI, often widespread.
- Traumatic macular retinoschisis is a significant diagnostic lesion.
- Vitreoretinal traction and orbital tissue trauma are implicated in the pathogenesis of ocular findings.
Conclusions:
- Ophthalmologists play a crucial role in documenting ocular findings in suspected AHI.
- Comprehensive autopsy, including ocular and orbital tissue examination, is essential.
- While differential diagnoses exist, clinical presentation combined with systemic findings typically confirms AHI.

01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
