Abstract: The OH/IR stars are oxygen-rich, cool giants that lose matter in the Asymptotic Giant Branch (AGB) phase. In the Galactic Bulge region, they have a visible light variation. From the time-series photometric databases in the V-band from the MACHO, OGLE, ASAS and EROS-2 projects, we retrieved the light curve of 29 OH(1612MHz)/IR in the bulge. By the PDM method, the characteristics of their light variation are analyzed.
