We show that the propagation of photons in a nonlinear dielectric medium can be described in terms of a modification of the metric structure of space-time. We solve completely the case in which the dielectric constant $\ensuremath{\epsilon}$ is an arbitrary function of the electric field $\ensuremath{\epsilon}(E).$ The particular case of no dependence on the field reduces to the Gordon metric.
