A laser treatment apparatus for irradiating an affected area of a patient with a treatment laser beam is disclosed. In the apparatus, the treatment laser beam is emitted by a laser source and delivered to the affected area through a treatment laser beam irradiation optical system to irradiate the affected area. An aiming light delivery optical system forms plural aiming light beams so that an optical axis of the treatment laser beam irradiation optical system is put between the aiming light beams, and delivers the plural aiming light beams to the affected area so that the aiming light beams are focused on a position on which the treatment laser beam is to be focused. During this focusing, the aiming beams are being rotated manually or automatically by a manual rotation mechanism or an automatic rotation mechanism. The rotating mode of the aiming beams is selected with a selection switch from a manual rotation mode and an automatic rotation mode.
