Abstract
Our goal is firstly to derive a revision of the basic theory of $D_{-\omega}$-semi-classical orthogonal polynomials and secondly to study the discrete semiclassical character of two standard perturbations of a $D_{\omega}$-semiclassical form into detail. Some illustrative examples are given.
