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.The ophthalmologist should emphasize this and strongly recommend further investigation if not previously undertaken. Correlation between retinal abnormalities and intracranial abnormalities in the shaken baby syndrome.
Then, using the scaling parameters, he estimated that less rotational acceleration would be required to produce concussion in the larger human brain, perhaps on the order of 6,000 to 7,000 radians/sec.""It is significant to note that whereas this experiment showed, qualitatively, that rotation alone could indeed produce intracranial injury, it was not shown quantitatively that human beings could generate the required rotational acceleration by manual shaking."Yet no laboratory proof of this possibility has ever been put forth.Violent shaking is a type of child abuse which may cause intracranial hemorrhages combined with retinal and vitreous bleeding.Fundus bleeding is similar to that in ophthalmological examination is most important to detect fundus bleeding, which, in the absence of birth trauma or any other supportive evidence of external trauma or other diseases, is the leading symptom of the shaken baby syndrome. [Traction retinal detachment, optic atrophy, apallic syndrome after shaking trauma in an infant] [Article in German] Grote A.During the next months optic atrophy, subretinal fibrosis at the posterior pole, neovascularisation at the optic disc and non-rhegmatogenous retinal detachment developed. DISCUSSION: Non-accidental injuries can cause direct trauma and indirect traumatic sequelae.Retinal haemorrhages, especially in conjunction with unexplained trauma or changes of consciousness should arouse suspicion of shaken baby syndrome.
