PROBLEM TO BE SOLVED: To provide an ophthalmological treatment device capable of surely treating a neovascular lesion without affecting normal tissues. SOLUTION: Laser beams from a laser beam source 1 for treatment and a laser beam source 5 for diagnosis are two-dimensionally deflected by a light deflection element 8 and a galvano-mirror 13, are irradiated to an eyeground and the eyeground images are displayed on a monitor 26. A photosensitive material provided with a specific accumulation property to a neo vascular is administered to a person to be tested, the fluorescent images of the eyeground are observed and a part including the neo vascular is specified. At the time of treating a disease part, the laser light source 1 for the treatment is operated, and when a light beam scans the specified disease part, the intensity of the light beam is reinforced through a control circuit 29 and a driving circuit 28 for driving an optical modulator 2. In the constitution, since the disease part is surely specified and the light intensity of the laser beam is reinforced at the part, only the neo vascular is surely nectrotized or closed. |
