The evolution of central stars of planetary nebulae was hitherto documented in just a few cases. We look for evolutionary changes of the [OIII] 5007A line flux in the spectra of planetary nebulae. We compared nebular fluxes collected over a time interval of a decade or more. We used literature data and newly obtained spectra. A grid of Cloudy models was computed using existing evolutionary models and compared with the observations.
