QCD Studies in Two-Photon Collisions at CLEO

We review QCD results of CLEO two-photon analyses and discuss the measurements of two-photon partial widths of charmonium and cross sections for hadron pairs production, antisearch for glueballs and the measurements of $\gamma^*\gamma \to$ pseudoscalar meson transition form factors. We emphasize the importance of other possible analyses, favorable trigger conditions and selection criteria of the presently running experiment and the advantages of CLEOc - the future $\tau$-charm factory at Cornell with the existing CLEO III detector.
