[Corneal changes in patients on dialysis for renal failure (author's transl)].

The corneas of 100 patients on dialysis for renal failure were observed. In 52 patients follow up studies were possible. 55 patients demonstrated limbal changes. On slit lamp biomicroscopy these changes showed to be similar to the white limbus girdle described by Vogt. Small limbal biopsies from five patients on dialysis were studies histopathologically and compared to biopsies from three patients with normal renal function. Only patients on dialysis showed senile elastosis and three of them epithelial and subepithelial hyaline deposits. Calcium deposition was the same in both groups.
