Actual eyes don't seem to be a part of the soul, just a physical part of the body. Otherwise, both Itachi and Nagato would be missing their eyes in the Edo Tensei version because these eyes were later taken by someone else (i.e. Sasuke and Obito respectivelly), and while Nagato's eyes weren't his own, at least that's not the case with Itachi. So, these eyes are just a pure flash and blood, maybe, they have their "soul" counterparts the same way as arms, but these counterparts seem to depart with the rest of the soul when it leaves the body.
