I thought I was going to get an answer....
Oops....somehow I lost track of your question. Gotta love these computers, eh? Or maybe I'm starting to come down with oldsheimers disease :(
You son has sustained a major injury to his eye. Unless he can be seen in the ER by an ophthalmologist on-call, being examined by a regular ER doc will not be of much use.
I suggest you get him in to see an ophthalmologist first thing in the morning. If you tell the staff the nature or your son's injury and his symptoms I am sure that they will squeeze him into the schedule right away.
Does this make sense to you?
And, now, the obligatory word from our sponsors: :o)
