OD2b77,
I think in this case it would be a little early to jump the gun and label your partner a bad OD. Much as we would all like to think differently, doctors occassionally make errors. Long before you rethink your partnership or form an opinion of your partner, you need to actually DISCUSS the issue with your partner. Glaucoma's a tricky disease. You need to find out why s/he did what s/he did. If you can't discuss something like this openly with a partner, your partnership is already in big trouble. If your gut instinct to this situation is to think about dissolving the partnership instead of communicating, I'd strongly advise you against ever entering into a partnership.
As for the patient, just tell them that glaucoma develops over time, they didn't have it before, they have it now, and they need treatment.
I have a dentist friend who tells me about a patient he saw with fillings and work that just looked awful. His first instinct was to wonder what kind of quack had worked on him. He of course thought that he could do a much better job. When the patient asked him about the work, he bit his tongue, sai d it looked OK, but that he was going to touch it up. Turns out that the patient was horribly uncooperative, moved all over the place, and was very skittish. Because of the patient, by the end, my friend's work didn't look any better than what he thought he would fix. Goes to show that if you weren't there at those exams, you never know exactly what occurred.
Now this is different than seeing a pattern. If one of your patients come back from the cataract surgeon with a torn up iris, then maybe that patient coughed during surgery. If every third patient comes back like that, you have an ethical obligation to find another surgeon. Or if you start to review your partner's charts and see a pattern of problems, then you could think about dissolving your partnership.
