  We examine the optical properties of two different configurations of an
ordered liquid crystal film on a catenoid forming coreless disclinations. We
find the effective optical metric from which we obtain the geodesics and wave
modes characterizing thus the propagation of light on this surface. We show
that the optical metric describes a two-dimensional section of the spacetime of
a conical wormhole.
