He is shown in a flashback with the normal Sharingan when Hagoromo shows that Sasuke is his incarnation.

I guess he didn't need it, the amount of Yin chakra he had was enough for him to not go blind.

I see the Sharingan as a focus point for the ability, the lens of a supercomputer capable of seeing bacteria. No lens, no possibility to see them.

You have the super computer but no lens, you can't see them, yet if you have years of experience then you can see something, which would be Madara's case, the abilities was in his blood, he needed the eyes for Perfect full body, but because of experience, he could summon a normal one without his eyes.

It all depends on how powerful the Yin of the person is, when Sasuke gained Itachi's eyes, his own chakra was modified with it.

I guess that Indra's Yin was so powerful that he didn't need to switch.

It most probably is something that occurs because with the passing generations and the mix of blood, their bodies stop being like that of Indra.
