Taking one's eye out in battle seems weird to me, as does the idea that Danzou has a technique up his sleeve he didn't show during the fight against Sasuke. It's theoretically possible, but I don't think so. The only realistic option is poison.
I guess we just have to accept the fact that he somehow made it.
Did anyone discuss why Itachi never implanted himself Shisui's eye? One EMS and one MS might have been a bit weird, but it's still better than turning blind on both eyes.
