My nephew who is 11 months old has a retinal hemorrhage. He had surgery on it this past Friday, and went in today for his check-up with his peditrician. His doctor called DeFax on my sister claiming that she or her husband shook the baby when he was younger, and that shaken baby syndrome caused his retinal hemorrhage. I know for a fact that they didnt do that. They would never harm either of their children. What are some things that can cause this in infants? I need serious advice!!! HELP!!!!
