Abstract
We show that a Lagrangian, Lorentzian surface $M^2_1$ in a complex space form $\widetilde{M}^2_1 (4c)$ is pseudo-isotropic if and only if $M$ is minimal. Next we obtain a complete classification of all Lagrangian, Lorentzian surfaces which are lightlike pseudo-isotropic but not pseudo-isotropic.
