Depends on if it s the whole eye, or just the pupil clouding.  If it's the eye itself its a bacterial infection, if its just the pupil it's usually a pH problem.  If you're going to try antibiotics start with a gram negative like neomycin.  Not as strong a tetracyclin, but it won't affect your bacterial filter.
