What's up with this guy's eye?

[pcfriedrich]

I was doing a water change today, and noticed the bottom half of my midevil's iris is swollen. Its completely clear, almost looks like an air bugble is stuck to his eye. The only eye diseases I can find searching online is popeye, and this doesn't appear to be that. What could it be, and what could cure it?

oh yeah, crappy pic:

Nobody knows, or has any ideas what it could be, or how to cure it?

I do not know. Might be nothing in the short run, a minor injury.

Try and add some aquarium salt.

I just kept an eye on it. Was getting better by the day, rather than worse. probably just a minor injury from one of the rocks in my tank.
