help! My sailfin tang's eye!

[dr5271]

i came home today and noticed that on the right side of my sailfin tang, his eye seems to be foggy, or scratched, it kinda looks like popeye, its not as poped out as i have seen other fish effected by this. it almost looks like he scratched his eye on rock or something and now its foggy and protruding slightly. it also looks like there MAY be some tiny white specs on that side as well. could anyone tell me maybe what this may be, how it happened, what could possibly be the cause of this! thank you any help is appreciated.
P.S. my other fish in the tank, (2 fire fish, maroon clown, coral beauty look fine and healthy)

I moved this thread to Disease and Treatment so that it gets more attention. How long have you had the tang?
