Invisible creatures get taken off the map, if no PC can see them. The DM will have to keep track of where they move.
A blind character gets helpful advice from the rest of the party to help him find the enemies.
I base these rulings on the fact that a stealthy PC must have total concealment from all enemies and beat the passive perception of all enemies before they can be considered hidden from any of them - presumably because the monsters shout out warnings to each other. If monsters can warn each other of hidden enemies, so can PCs.
