It sounds like he is having trouble with his facial nerve. Yes, there is help for him. However, in the interum it will very important that his eye doesn't get into problems from exposure and drying. The frequent use of an artificail tear like Systane and the use of Lacrilube ointment, particularily at bedtime, will help prevent exposure. Both are available over the counter.
As I see that you are off line and can't do this " Live Chat", I'll switch to Q and A. When I hear back from you we'll discuss the facial nerve options. And you can continue to ask questions.
Just type a message in the box and I will get back to you.
