The QED Callan-Symanzik β function is calculated for a certain class of higher-order photon self-energy diagrams within the framework of perturbative QED. It is found that the formulation of de Rafael and Rosner is valid up to the sixth order but must be modified from the eighth order on. Correction terms are evaluated explicitly. The result, applied a renormalization group calculation of an eighth-order contribution to the muon anomalous magnetic moment, gives a good agreement with the exact numerical evaluation.
