Hi Anon - Thanks for writing. I can understand why you're concerned.
Retinal hemorrhage is the abnormal bleeding of the blood vessels in the retina, the membrane in the back of the eye. Retinal hemorrhages can be caused by injuries, usually forceful blows to the head during accidents and falls, as well as by adverse health conditions. In infants, retinal hemorrhage is frequently associated with child abuse and has been termed shaken baby syndrome.
The medical literature shows cases of retinal hemorrhage in infants caused by both accidental and non-accidental injury. It would be important to find out if your nephew was involved in a fall or other accident which could have caused his injury in order to demonstrate the cause of his retinal hemmorrhage.
Does this answer your question?
