I will review a series of works on rheology of glasses based on the infinite dimensional solution of structural glass models.I will discuss the phase diagrams of Hard and Harmonic spheres glasses and describe their behavior under strain deformations.  I will first focus on the small strain elastic responses and their statistical properties and then I will analyze the strongly non linear regime of large strain deformations. The theory predicts and captures some relevant phenomena ranging from the Gardner transition, the yielding transition and shear-jamming.
