Okay kiddo, let me explain Adie Syndrome in a way that even a 5-year-old can understand.
Our body has a part called the Autonomic Nervous System (ANS) that helps our body do things like breathing, digesting food, and regulating our heart rate. But sometimes, things can go wrong and our ANS doesn't work the way it should.
Adie Syndrome is a problem with the ANS that affects our eyes. It's when one of our pupils (that's the black part in the middle of our eyes) is bigger than the other and doesn't get smaller or bigger when it should.
It's sort of like having one eye that's always open wide and the other eye that's always half-closed. This can make it hard to see clearly because our eyes aren't working together the way they should.
Doctors can diagnose Adie Syndrome by shining a light in our eyes to see if our pupils react the way they're supposed to.
But don't worry, if someone has Adie Syndrome, it's not usually something to be scared of. Sometimes it can go away on its own, and other times it can be treated with medicine or special eye exercises.
