well, Madara didn't have eyes because they were removed and were given to Nagato. the reanimated eyes are fake. If you think about it the reanimation of Madara to youth was the modification done by Kabuto when Obito gave Madara's body since he died after getting old. And the modification and Rinne rebirth helped him gain access to his powerful state.
