Rhesus monkeys were strapped into the chair with their heads free to rotate.The piston then impacted the chair, simulating a rear-end motor vehicle collision." "Measuring the arc of the head rotating and accelerating around the neck, Ommaya was able to demonstrate that a rotational acceleration of 40,000 radians/sec was sufficient to cause concussion in the animal subjects.In this retrospective review, ophthalmoscopic and intracranial abnormalities were correlated.RESULTS: The age of patients ranged from 2 to 48 months (mean - SD, 10.6 /- 10.4 months). Findings included subdural hematoma (70 children, 93%), cerebral edema (33 children, 44%), subarachnoid hemorrhage (12 children, 16%), vascular infarction (nine children, 12%), intraparenchymal blood (six children, 8%), parenchymal contusion (six children, 8%), and epidural hemorrhage (one child, 1%).PATIENTS: Between 19 In two cases a vitrectomy was performed. In two children intraocular bleeding resolved completely, three children developed mild to severe amblyopia and two children became blind. CONCLUSIONS: Sudden cerebral symptoms or intraocular bleedings in otherwise healthy young children are suspicious for child abuse. Thus funduscopic examination in mydriasis is obligatory.The prognosis depends on the severeness of ocular hemorrhages and cerebral lesions.CASE REPORT: A 6-week-old infant with no history of systemic disease or trauma was admitted to the children's hospital because of a disorder of consciousness, respiratory insufficiency, taut fontanel and dilated pupils with sluggish reaction to light. Ophthalmological examination showed no signs of trauma in the anterior segment.
A contoured fiberglass chair was built, mounted on wheels, and placed on tracks with a piston behind it.A 12-year ophthalmologic experience with the shaken baby syndrome at a regional children's hospital. Department of Ophthalmology, Medical College of Wisconsin, Milwaukee, USA.PURPOSE: To examine the ophthalmologic experience with the shaken baby syndrome (SBS) at one medical center, including clinical findings, autopsy findings, and the visual outcome of survivors.Sixty-four (64/75, 85%) children had retinal abnormalities, mostly (53/64, 82%) confluent multiple hemorrhages that were subretinal, intraretinal, and preretinal in 47/64 (74%) and bilateral in 52/64 (81%).No association was found between anatomic site (left, right, or bilateral) of intracranial and retinal findings (Mc Nemar test kappa = -0.026-0.106) or between any of the intracranial findings mentioned above and the following retinal findings: normal or abnormal retinal examination, multiple ( 1999;5-81.
