I know this may sound like a strange question? My son has always had a droopy eye lid and when he gets tired, his right eye will look like a lazy eye. Through the past years doctors have asked about this. It does not interfere with his vision but this has been going on since he was quit young. I'm just wondering if this could have been a sign of a motor tic and no one realized this. He has been checked for Graves and Myst Gravis. Any ideas?
