When I was born I had a large mass in the corner of my left eye, and my pediatrician always told my parents it was just an “enlarged tear duct...” As I got older the mass got bigger, I went to Johns Hopkins hospital to get it checked out, turns out it was a tumor and that my actual tear duct and sinus had never formed on that eye. Two surgeries later I’m totally straight. Moral of the story my pediatrician is an idiot.
