We consider the constraints on the fraction of dark matter in the universe in
the form of primordial black holes taking into account the crucial role of
accretion which may change both their mass and mass function. We show that
accretion may drastically weaken the constraints at the present epoch for
primordial black holes with masses larger than a few solar masses.
