METHOD AND APPARATUS FOR IRRADIATING SENILE MACULAR DEGENERATION

摘要

The invention concerns a device for controlling a gamma radiation beam for treating by irradiation ocular lesions and particularly for treating subretinal neovessels of senile macular degeneration. The invention is characterised in that it consists, in a first step, in focusing the rays of a radioactive source with a cylindrical collimator having fixed stages of small diameter; and, in a second step, directing the radiation beam on the macular zone using an adjustable luminous marker (4) and a mobile seat (5). The invention also concerns the implementation of said method in an apparatus for treating ocular lesions.
