One of my 18 month old twin daughters has Duanes Syndrome. Hers is bilateral and we have been going through hearing exams. Please feel free to contact me. I was devastated when they told me but more so because they said this was permanent and there was nothing that could be done. I did some research and found out how important it was to get hearing evaluations done as well.
I have hooked up with Boston Children's Hospital here in the United States because they are doing research on the genetic Duanes. They have loads of info.
This is also a web site that offers some additional info.
