We study multiple light scattering in ordered nematic liquid crystals from long-range dielectric fluctuations. The mass operator is calculated in the first Born approximation of Dyson's equation for the average amplitude. New results are found concerning the spectral function. In addition, the average intensity is obtained numerically using a Monte-Carlo simulation. We simulated the anisotropic shape of the coherent backscattering cone, the time-of-flight distribution functions and the polarization in the diffusive regime.
