To Feivel,
She wasn’t looking for a medical opinion, she was looking for a definition.
To Mybat,
It’s a good idea in your case to get a second opinion based on a physical exam, because of the possibility of surgery. Sometimes you need surgery in these types of cases, sometimes you don’t. You can go to Wills eye hospital in Phila.,Pa. They have pretty good pediatric specialtists. Look up contact info online.
