Abstract:
A laser treatment apparatus used for performing treatment on a treatment part of a patient's eye by irradiating the treatment part with a laser beam for treatment, the apparatus including:a treatment beam irradiation optical system for irradiating the treatment beam, the system including a mirror which reflects the treatment beam toward the treatment part; mirror moving means for moving the mirror to change a point to be irradiated by the treatment beam; detection means for detecting motion of the mirror; control means for controlling irradiation of the treatment beam based on detection results by the detection means; irradiation command signal input means for inputting an irradiation command signal to perform the irradiation of the treatment beam, wherein the control means stops the irradiation of the treatment beam when the detection means detects that the mirror is moving while the irradiation command signal is input: and selection means for selecting a repeat mode in which, during the input of the irradiation command signal, the treatment beam is repeatedly irradiated according to a preset time interval, wherein when the repeat mode is selected, the control means controls the irradiation of the treatment beam based on the detection results by the detection means and at the time interval.
