PROBLEM TO BE SOLVED: To collectively designate a large number of photocoagulation positions with every group by designating the photocoagulation positions of plural groups by a coordinate input means to set the photocoagulation positions on the eyeground by setting plural photocoagulation positions as a single group, and performing photocoagulation with every group unit. SOLUTION: A coordinate input device arranged in a system controller is composed of a position designating means such as a light pen or a mouse, and can designate photocoagulation positions on an eyeground image displayed on a television monitor and an erroneous trigger preventive control point directly or by using a cursor or the like. In this device, the coagulation positions are designated at once, and on actual coagulation, it is constituted so that photocoagulation of plural places is performed by a trigger of one time while precisely aligning them with every group by setting coagulation positions of the number coagulable in time when an eye to be examined will not probably move, that is, in 1 to 2 frame as a single group. |
