Abstract
Gravitational microlensing has proved to be a versatile astrophysical tool. Recently, the question of whether higher order relativistic corrections can influence the observable properties of microlensing has been addressed. This letter extends earlier studies, investigating higher order relativistic terms in astrometric shifts during microlensing events, revealing that they produce no effects. The magnitude of the relativistic corrections is examined in an astrophysical context and is found to be negligible.
