The turbidity measurements of Güttinger and Cannell [Phys. Rev. A 24, 3188 (1981)] in the temperature range 20mK < T - Tc < 29:5K along the critical isochore of homogeneous xenon are reanalyzed using the master crossover functions for the isothermal compressibility kt and the correlation length x, without adjustable parameter. We show that the turbidity data are well represented by the Ornstein-Zernike theory, within 1% precision. This excellent agreement conrms that the Ising-like critical behavior of xenon can be described in conformity with the universal features estimated by the massive renormalization scheme, only knowing the four critical coordinates of the vapor-liquid critical point in the (pressure, temperature, molecular volume) phase surface of the monoatomic xenon particle.
