[Radiotherapy of the juvenile xanthogranuloma of the iris (author's transl)]

A report is given on an eight months old child with a juvenile xanthogranuloma of the iris and a secondary glaucoma. After radiotherapy with 6 X 0,5 Gy under conventional deep therapy conditions, a soon regression of the increased intraocular pressure was observed. In case of a juvenile xanthogranuloma of the iris, this secondary glaucoma represents in any case an acute danger to the eye, so it must be treated immediately. Radiotherapy has to be considered as the method of choice; it is also discussed with regard to the risk and the avoidance of a radiation cataract which, however, has to be tolerated in certain cases in order to prevent greater troubles.
