Abstract:
1. An improved, accurate method of treatment of an eye's fundus, using a treatment optical system with a slit lamp assembly and fluorescence angiography, comprising the steps of: generating a treatment beam from a primary light source; creating a native digital image of an eye's retina using said treatment optical system and said primary light source; generating a secondary beam using a secondary light source; generating a digital reference image on an eye's retina at a predetermined position using said treatment optical system and said secondary light source; wherein said secondary light source operates at a different wavelength from said primary light source; controlling and processing said digital reference image and said native digital image by at least one computer to accurately determine a treatment zone; marking uniquely said treatment zone onto a corresponding region of said native digital image, wherein said treatment zone is marked by means of a software tool; adjusting said treatment beam and said treatment optical system to have said treatment beam cover said treatment zone; and irradiating said treatment zone.
