title: [Results of the 90Sr- and 90Y-radiation after surgical removal of 123 pterygia (author's transl)].
abstract: Out of 107 patients 123 pterygia were surgically removed: 24 pterygia of the progressive Type I, 49 of the semi progressive Type II and 50 of the regressive Type III. After surgical removal of the pterygia Type I and Type II followed a treatment with strontium 90 beta radiation with 2700 rep: 900 rep at the 2nd, 8th and 15th day after surgery. The recurrence rate was high in Type I (62%) and Type II (16%), but lower than it is reported in these groups operated without following radiation. More often pterygia of Type I and II are seen in people of the highlands.
