A laser treatment apparatus is to treat a site of disease of a patient with a laser beam. The laser treatment apparatus contains a source (1) of illumination light for irradiating a site of treatment of the patient and a site around the site of treatment with the illumination light; a source (2) of aiming light for irradiating the site of treatment with the aiming light; a light-receiving means (13) for receiving a light reflected from an aiming site to which the aiming light is applied and from a site around the aiming site; a setting means (14) for comparing a ratio of a quantity of light reflected from the aiming site, as received by the light-receiving means, to a quantity of light reflected from the site around the aiming site with a predetermined ratio; and a control unit (15) for controlling an illuminance of the aiming light with respect to the illumination light by adjusting a ratio of the quantity of light reflected from the aiming site to the quantity of light reflected from the site around the aiming site so as to reach a predetermined ratio.
