PROBLEM TO BE SOLVED: To provide a laser treatment apparatus and a laser treatment auxiliary program which allow an operator to easily recognize the progress situation of treatment of a patients eye with laser beam.SOLUTION: The laser treatment apparatus irradiates tissues of a patients eye with laser beam, and can control display of an image on a display screen. The CPU of the laser treatment apparatus accepts designation of an irradiation planned area being a planned area of irradiation with laser beam (S1). The CPU causes the display screen to display the accepted irradiation planned area (S3). When the tissues of the patients eye is irradiated with the laser beam, the CPU causes the display screen to display an irradiated area being an area having been irradiated with the laser beam (S13).
