Locally inhomogeneous cosmological models have been proposed since the sixties. Recently these models have been revisited in order to explain the observed accelerated expansion of the universe. Application of the optical scalar equations in such models has given estimates of the distortions in the observations of distant objects and the distance-redshift relations. In this work we analyze the influence of local inhomogeneities on the trajectory of light beams, testing the ZKDR luminosity distance with three cosmological probes: supernovae Ia, gamma-ray bursts and Hubble parameter measurements, in a wide redshift range of \(0.1<z<8.1\).
