I'm not sure if this is true or not, but it seems likely. There are also those who say it brings back to life the way you die. Hence why Itachi and Nagato had their eyes. But I don't think it brings them back in their prime, otherwise Nagato wouldn't have needed Itachi for a little bit.
actually edo tensei brings back the person at the time of death and when itachi died his eyes were not gone just like when nagato died his hair was white
