[Occurrence of diffusions shown by fluorescence angiography of the laser coagulation in animals (author's transl)]

Laser treated rat fundi were observed angiographically and with the fluorescence microscope for 3 months. Angiographically diffusions have been observable up to about one week post laser, fluorescence microscopically, however, for the whole observation time of 3 months. From the 2nd week, these diffusions were produced mainly by neovascularizations which angiographically were not visible. They started from the choroid and penetrated into the outer part of the retina.
