The present concerns ophthalmology. This invention can be used for the treatment of retina degeneration diseases, particularly for macular degeneration treatment. A method of the macula degeneration treatment by irradiating of the retina damaged areas through the pupil wherein the technique of the irradiation performed by the quasi-monochromatic light pulse in visible and near infra-red spectral range with energy that does not exceed 10-5 joules. A device for the macula degeneration treatment that consists of radiation source, radiation directional pattern forming means, means to deliver the radiation to the given part of the retina through the pupil, power supply unit, and indicator and control unit; the device comprising at least one light emitting diode (LED) is used as the source of radiation.

La présente invention concerne l'ophtalmologie. Elle peut servir au traitement des maladies dégénératives de la rétine, particulièrement au traitement de la dégénérescence maculaire. Le procédé objet de l'invention permet le traitement de la dégénérescence maculaire par l'irradiation des zones affectées de la rétine à travers la pupille, l'irradiation étant réalisée par une impulsion lumineuse quasi-monochrome dans le domaine spectral visible et proche infrarouge avec une énergie n'excédant pas 10<SUP>-5</SUP> joules. Le dispositif pour le traitement de la dégénérescence maculaire objet de l'invention se compose d'une source de rayonnement, de moyens de formation d'un profil directionnel pour diriger le rayonnement sur la zone souhaitée de la rétine à travers la pupille, une unité d'alimentation et une unité d'affichage et de commande, il comprend au moins une diode électroluminescente (DEL) utilisée comme source de rayonnement.
