An ophthalmic laser treatment apparatus, which allows SLT to be performed by a laser source not having a Q-switch which emits a continuous wave laser beam, has a laser source capable of emitting a continuous wave visible laser beam to be absorbed into pigment cells of trabecular meshwork, an irradiation optical system for directing the laser beam to a patients eye so as to irradiate the eye with the laser beam, a device for pulsing the laser beam by controlling a driving duration of the laser source or opening and closing durations of a shutter in the irradiation optical system, a device capable of setting an irradiation duration of the laser beam within a range of 0.1 msec to 5 msec in order to perform Selective Laser Trabeculoplasty, and a device capable of setting irradiation energy density of the laser beam within a range of 1 J/cm2 to 8.5 J/cm2.
