Hi, Its really hard to tell from the pic, but from your description it sounds likes the fish had Popeye? swollen eyes? Sometimes the swelling can be so bad as to rupture the eye from the pressure.
I'm sorry to say it but odds are if that has occurred the fish will be blind in that eye, and may be susceptible to further infection. Can you take a better pic?
What kind of bacterial problem did they have?
