This is Riverton. He's the wild caught Iowa male Plains Garter snake(T.radix) I purchased last year.
About a week ago I was feeding his group. I had given him a night crawler and he and all but finished it when a cage mate bolted toward him and attempted to grab the small piece of worm that was hanging out of his mouth.
Inadvertently his eye was struck and it ruptured.
He seems to be doing well with it and I'm hoping over time it will repair itself.
