Patent ID: 10485703

Abstract:
Operations of a laser treatment apparatus are facilitated. A laser treatment apparatus of an embodiment includes an illumination system, observation system, irradiation system, illumination-area changing part, irradiation-condition setting part and controller. The illumination system illuminates an eye fundus. The observation system is used for observing the fundus illuminated. The irradiation system irradiates aiming light of a preset pattern and treatment light consisting of laser light of a pattern determined based on the preset pattern onto the fundus. The illumination-area changing part is used for changing an illumination area of the fundus by the illumination system. The irradiation-condition setting part sets irradiation condition of the aiming light and/or treatment light from the irradiation system. The controller controls the illumination-area changing part based on the set irradiation condition to change the illumination area.
