An ophthalmic treatment apparatus uses therapy and diagnostic laser light sources whose beams are deflected two-dimensionally via an optical deflector and a galvanomirror and directed on the eye fundus to produce a fundus image on a display monitor. A photosensitive substance that accumulates specifically in neovascular regions is administered to the patient to define the region where the neovascular tissues are located. When the region is to be treated, the therapy laser light source is activated and its intensity is amplified by a controller and a driver for driving a light modulator. This arrangement assures a reliable definition of the affected region and enables only the neovascular tissues to be destroyed or sealed off because the laser intensity can be amplified at the region concerned.
